What Are The Signs Of Mouth Cancer Biography

Genital human papillomavirus (HPV) — a sexually transmitted infection — is the most common cause of cervical cancer. When a woman is exposed to HPV, her immune system usually prevents the virus from doing any serious harm. But in a small number of women, the virus survives for years. Eventually, the virus can lead to the conversion of normal cells on the surface of the cervix into cancerous cells.

At first, the cells may only show signs of a viral infection. Eventually, however, the cells may develop precancerous changes. This is known as cervical intraepithelial neoplasia. Typically, the precancerous changes go away spontaneously. In some cases, however — particularly for women who have altered immune systems — cervical intraepithelial neoplasia may eventually progress to invasive cervical cancer.

It's not clear why some women are more likely to develop cervical cancer. Some types of HPV are simply more aggressive than are others. Cigarette smoking also increases the risk of cervical cancer. In fact, according to the American Cancer Society, women who smoke are about twice as likely as nonsmokers to develop cervical cancer.

There are two HPV vaccines available — Gardasil and Cervarix. They offer protection from several of the most dangerous types of HPV. Gardasil is approved for boys and men, girls and women ages 9 to 26. Cervarix is approved for girls and women ages 9 to 25.

Remember, if you're sexually active, the best way to prevent HPV and other sexually transmitted infections is to remain in a mutually monogamous relationship with an uninfected partner. When you have sexual intercourse outside of a long-term monogamous relationship, always have your partner use a condom. Regular screening for cervical cancer and precancerous changes of the cervix is important, too.

Signs Of Oral Cancer Biography

Three quarters of the way through his "biography" of cancer, the New York-based oncologist Siddhartha Mukherjee pauses to set the scene in his laboratory, a beehive of esoteric activity and impenetrable jargon. In lesser hands, such a passage would leave non-specialist readers bewildered and bored. But then he describes himself in the simplest of scientific poses, looking into a microscope. And what he gazes at is one of the more sinister mysteries of human – or anti-human – life. The leukaemia cells he is examining came from a woman who has been dead for 30 years. Unlike their discarded host, these cells are "immortal".

In this small but typical moment, Mukherjee manages to convey not only a forensically precise picture of what he sees, but a shiver, too, of what he feels. "The cells look bloated and grotesque, with a dilated nucleus and a thin rim of cytoplasm, the sign of a cell whose very soul has been co-opted to divide and to keep dividing with pathological, monomaniacal purpose."

The yoking of scientific expertise to narrative talent is rare enough, but the literary echoes of The Emperor of All Maladies suggest a desire to go further even than fine, accessible explanation. "Normal cells are identically normal; malignant cells become unhappily malignant in unique ways."

It takes some nerve to echo the first line of Anna Karenina and infer that the story of a disease is capable of bearing a Tolstoyan treatment. But that is, breathtakingly, what Mukherjee pulls off. He calls this great and beautiful book a biography, rather than a history, because he wants his reader to understand his subject not just as a disease, a scientific problem or a social condition, but as a character – an antagonist with a story to tell through its eerie relationships to the wider biological and animal world that is also, inexorably, our story.

Though it has many historical antecedents, the epic medical quest to understand and treat cancer only really took shape as it emerged as a defining disease of modernity. This is the case not just in the metaphorical sense that it speaks potently to our industrialised terrors, but in the direct sense that cancer only became a leading cause of death in the world when we began to live long enough to get it.

People in the past tended to die of other diseases – as they still do in poorer countries today. Cancer now ranks just below heart disease as a cause of death in the US, but in low-income countries with shorter life expectancies, it doesn't even make the top 10. At the beginning of the 20th century, life expectancy at birth in America was 47.3 years. Now, the median age at diagnosis for breast cancer is 61; for prostate cancer, 67. As we extend our lives, Mukherjee writes, "we inevitably unleash malignant growth".

Thus the scene is set for a monumental scientific, political and human struggle. Mukherjee assembles a teeming cast of characters: from ancients such as Atossa, the Persian queen who in 500BC self-prescribed the first recorded mastectomy, to Mukherjee's own patients. There are tales of grizzly surgical techniques and astonishing medical discoveries. But, as with any epic narrative, the central drama marches towards a war.

The full-blown campaign against cancer began with the meeting in the 1940s of an American socialite, Mary Lasker, in search of a great medical cause, and the driven cancer researcher, Sidney Farber, one of the creators of chemotherapy. Mukherjee describes it as the coming together of two travellers, "each carrying one half of a map". The battlefield at the middle of the map was Washington DC and the political alliance that Lasker and Farber eventually formed was with Richard Nixon. The passing in 1971 of the National Cancer Act enshrined the idea of cancer as sovereign among diseases and bequeathed it the language of a world war.

But as Mukherjee's narrative unearths his central character, and our understanding of cancer accumulates depth and complexity, the notion of a war becomes ever more threadbare. Its combatants had been configuring the enemy they needed to fight the war they wanted. Yet the story of science, Mukherjee observes, is not just one of discovery, but of the discovery of failure. The practitioners of surgery, radiation and chemotherapy had proceeded to treat cancer without understanding its fundamental mechanisms.

Crusaders for a magic bullet, including Farber, were scornful of calls to wait on the development of genetic research, or to emphasise prevention, or to appreciate the need for care as much as "cure". To many who had worked on the front lines, relentlessly pushing patients to the brink of death to save them, such calls seemed academic. And then the academics called time out.

In 1986, in The New England Journal of Medicine, John Bailar and Elaine Smith published a cold assessment of comparative trends in cancer mortality over the years. This revealed what they called a "qualified failure". Between 1962 and 1985, though duration of survival had improved in certain areas, the war on cancer had not only failed to show overall progress, but deaths from cancer had actually increased by 8.7%. Even accounting for the postwar boom in smoking-related lung cancer, Mukherjee writes, this "shook the world of oncology by its roots".

It is from here, as he reaches for the final act in his historical drama, that it becomes clear that Mukherjee is doing more than providing an account of medical developments, scientific discovery and human suffering. The underlying structural dynamic of his book turns out to be the riddle of progress itself, the application of reason and science to chaos and disease – the uber-project of modernity that, even if it has achieved too much to be called a failure, can never finally succeed.

As he turns inwards, to questions of the basic biology of the cancer cell, Mukherjee modifies his assessment of the war on cancer, from qualified failure to qualified success. There may have been no movement of the front lines of death, but if the aims could change, from utopian notions of eradicating death to more modest ambitions for the extension of life, then the result for medical science is a "dynamic" equilibrium rather than a "static" one.

He returns to the cell itself, as genetic knowledge began to offer results that could be applied clinically – the search for causes finally coming together with the search for cures. By the end of the 1990s, the development of Gleevec as a genetics-based drug treatment for chronic myeloid leukaemia had, as one researcher put it, proved a principle: "It demonstrates that highly specific, non-toxic therapy is possible."

The cellular composition of cancer is Mukherjee's own field, but he is under no illusions that the new era will leave history behind, or that gene-based therapies will lead us out of the cancer age. Harold Varmus, accepting his Nobel prize for the cellular origin of retroviral oncogenes in 1989, turned to Beowulf: "We have only seen our monster more clearly and described his scales and fangs in new ways – ways that reveal a cancer cell to be, like Grendel, a distorted version of our normal selves."

The idea that cancer cells are copies of who we are is, Mukherjee emphasises, not a metaphor. "We can rid ourselves of cancer," he concludes, "only as much as we can rid ourselves of the processes in our physiology that depend on growth – ageing, regeneration, healing, reproduction."

And so his intensely vivid and precise descriptions of biological processes accumulate into a character, fully developed and eerily familiar. The notion of "popular science" doesn't come close to describing this achievement. It is literature.

In his last years, Steven P. Jobs veered from exotic diets to cutting-edge treatments as he fought the cancer that ultimately took his life, according to a new biography to be published on Monday.

His early decision to put off surgery and rely instead on fruit juices, acupuncture, herbal remedies and other treatments — some of which he found on the Internet — infuriated and distressed his family, friends and physicians, the book says. From the time of his first diagnosis in October 2003, until he received surgery in July 2004, he kept his condition largely private — secret from Apple employees, executives and shareholders, who were misled.

Although the broad outlines of Mr. Jobs’s struggle with pancreatic cancer are known, the new biography, by Walter Isaacson, offers new insight and details. Friends, family members and physicians spoke to Mr. Isaacson openly about Mr. Jobs’s illness and his shifting strategy for managing it. According to Mr. Isaacson, Mr. Jobs was one of 20 people in the world to have all the genes of his cancer tumor and his normal DNA sequenced. The price tag at the time: $100,000.

But the 630-page biography spans Mr. Jobs’s entire life, and also includes previously unknown details about his romantic life, his marriage, his relationship with his sister and his business dealings. Mr. Isaacson conducted more than 40 interviews over two years with Mr. Jobs, who died on Oct. 5.

A copy of the book was obtained by The New York Times before it officially went on sale.

In October 2003, Mr. Jobs got the news about his cancer, which was detected by a CT scan. One of his first calls, according to the book, was to Larry Brilliant, a physician and epidemiologist, who would later become the head of Google’s philanthropic arm. The men went way back, having first met at an ashram in India.

“Do you still believe in God?” Mr. Jobs asked.

Mr. Brilliant spoke for a while about religion and different paths to belief, and then asked Mr. Jobs what was wrong. “I have cancer,” Mr. Jobs replied.

Mr. Jobs put off surgery for nine months, a fact first reported in 2008 in Fortune magazine.

Friends and family, including his sister, Mona Simpson, urged Mr. Jobs to have surgery and chemotherapy, Mr. Isaacson writes. But Mr. Jobs delayed the medical treatment. His friend and mentor, Andrew Grove, the former head of Intel, who had overcome prostate cancer, told Mr. Jobs that diets and acupuncture were not a cure for his cancer. “I told him he was crazy,” he said.

Art Levinson, a member of Apple’s board and chairman of Genentech, recalled that he pleaded with Mr. Jobs and was frustrated that he could not persuade him to have surgery.

His wife, Laurene Powell, recalled those days, after the cancer diagnosis. “The big thing was that he really was not ready to open his body,” she said. “It’s hard to push someone to do that.” She did try, however, Mr. Isaacson writes. “The body exists to serve the spirit,” she argued.

When he did take the path of surgery and science, Mr. Jobs did so with passion and curiosity, sparing no expense, pushing the frontiers of new treatments. According to Mr. Isaacson, once Mr. Jobs decided on the surgery and medical science, he became an expert — studying, guiding and deciding on each treatment. Mr. Isaacson said Mr. Jobs made the final decision on each new treatment regimen.

The DNA sequencing that Mr. Jobs ultimately went through was done by a collaboration of teams at Stanford, Johns Hopkins, Harvard and the Broad Institute of MIT. The sequencing, Mr. Isaacson writes, allowed doctors to tailor drugs and target them to the defective molecular pathways.

A doctor told Mr. Jobs that the pioneering treatments of the kind he was undergoing would soon make most types of cancer a manageable chronic disease. Later, Mr. Jobs told Mr. Isaacson that he was either going to be one of the first “to outrun a cancer like this” or be among the last “to die from it.”

According to Mr. Isaacson, his interviews with Mr. Jobs were occasionally punctuated by music listening sessions in Mr. Jobs’s living room. During one interview, Mr. Jobs played music from his new iPad 2, cycling through the Beatles, a Gregorian chant performed by Benedictine monks, a Bach fugue and “Catch the Wind” by the Scottish musician Donovan.

Mr. Jobs’s personal affinity for music, and his friendships with musicians, helped him maneuver deals to build the iTunes library and special versions of the iPod. It also moved into his private life at times, Mr. Isaacson writes. After Mr. Jobs learned he had cancer, he exacted a promise from Yo-Yo Ma to play at his funeral.

Mr. Jobs sometimes entertained business guests at his home. Rupert Murdoch, the conservative head of News Corporation, came twice for dinner. Mr. Jobs joked to Mr. Isaacson that he had to hide the kitchen knives from his wife, Laurene Powell, because of her liberal views.

The book provides new details on Apple’s business dealings and rivalries. The author recounts Mr. Jobs getting into a shouting match with co-founders of Google, Larry Page and Sergey Brin, in 2008, over Google’s development of Android software for smartphones, which would compete with Apple’s iPhone.

Mr. Jobs told Mr. Isaacson that he regarded Android as a “stolen product,” copying Apple technology.

In romance, Mr. Isaacson writes, Mr. Jobs fell hard, but often made it hard on the women in his life. In 1985, he met and fell in love with a computer consultant, Tina Redse. They lived together on and off for years, and Mr. Jobs proposed in 1989. But she declined, telling friends he would “drive her crazy.”

Later, he met Ms. Powell, a former Goldman Sachs trader who had enrolled at Stanford business school. They fell in love and she moved in with him. But his behavior could be maddening. On the first day of 1990, he proposed, and never mentioned it again for months. In September, exasperated, she moved out. The next month, Mr. Isaacson writes, he gave her a diamond engagement ring, and she moved back in. Eventually they married.

The book also offers some tidbits about Mr. Jobs’s legendary attention to detail, which, according to Mr. Isaacson, extended to a luxury yacht that he began designing in 2009. The design is sleek and minimalist, with 40-foot-long glass walls. It is being built in the Netherlands by the custom yacht firm Feadship, the book says.

Starting last spring, Mr. Jobs met individually or in pairs with people he wanted to see before he died. Bill Gates, co-founder of Microsoft, was one of them. He came to Mr. Jobs’s house in Palo Alto, Calif., in May, and they spent more than three hours together, reminiscing, Mr. Isaacson writes.

By 2011, Mr. Gates, though still Microsoft chairman, had for years focused most of his time on his huge charitable foundation. Mr. Jobs told Mr. Isaacson that Mr. Gates was happier than he had ever seen him.

They talked about the emotional rewards of family life and having children, and the good fortune to have married wisely. Mr. Gates later recalled to Mr. Isaacson the two laughed that Laurene had kept Mr. Jobs “semi-sane” and that Melinda, Mr. Gates’s wife, “kept me semi-sane.”

Amazon Author Rankbeta  (What's this?)

You remember the scene in the film "Butch Cassidy and the Sundance Kid"? From the top of the bluff looking into the distance at dusk, Butch sees the lights of the pursuing posse which doesn't stop tracking them even at night and says "How many are following us? They're beginning to get on my nerves. Who are those guys?" In the same threatening way cancers have been dogging human beings since the dawn of time, and although we now know quite a lot about cancer we still don't really know "who are those guys" or how to shake them. And they sure are "beginning to get on our nerves" as Butch said. Almost one out of four of us will eventually wrestle with cancer -- the defining illness of our generation -- and lose our lives in the process. Until it catches up with us most of us will try to ignore this fact, just as when we were very young children alone in our bedroom trying to go to sleep at night we tried to ignore the monster that we sometimes feared might be lurking in our bedroom closet.

Enter oncologist Siddhartha Mukherjee who almost parentally takes us by the hand to give us the courage to open with him the door to that dark and foreboding closet in order to see what is really lurking inside. Since eventually most of us are going to have to wrestle with this monster anyway -- either as a victim or as a loved one of a victim -- looking intelligently and closely into that dark closet does diminish fear and enhance wise perspective. And on this incredible journey into the depths of that darkness, what an absolutely marvelous guide is this modern day Virgil called Siddharta Mukherjee as he leads us on this long and often harrowing journey through the swarth that cancer has cut through mankind throughout time.

Mukherjee is a veritable kaleidoscope. Turn his writing one way and you experience him as an exciting writer of page-turning detective stories or mystery stories; turn him another and he's a highly effective communicator of cellular biology; turn him a third and you get superb science writing; turn him a fourth and he has the grandeur and broad sweep of an excellent historian. It's hard to believe that this one book, combining all of these appealing characteristics, is the work of just one man. And underlying it all is his sterling medical training and credentials which have been enumerated often elsewhere.

The book itself is a tour de force. It is the first book of such extraordinary scope regarding cancer. Its architectural structure brings to mind Melville's Moby Dick and how effectively and artfully Melville braided together the three strands of his great classic: a grand adventure story, the technology of whaling, and a treatise of humanity and philosophy. Equally effectively does Mukherjee weave together all the various facets of this iconic disease throughout history, from describing cancer from the patient's perspective, to viewing the never ending battles of physicians and medical researchers with cancer over the centuries, to examining the mysteries of the cellular nature of cancer itself and what really goes on in there, to the pro and con impact of this never ending plague on the spirit of the individual human and on our race as a whole, to peering into a crystal ball for a glance of cancer's and our future together. While doing all of this the alchemy of Mukherjee's writing continually turns science into poetry and poetry into science.

Simply put, it is so good, and so incandescently clear and lucid, and so powerful, and so engrossing, and so easily consumed that you will not lay it down without someone or circumstances forcing you to.

Had I read this book in my teens I would have found my life's career. I can only imagine that while you are reading this book, somewhere there will be some very young teenage girl or boy who will also be reading it at the same time you are, and who will become totally hooked by this book just as you will be, and who will go on to make a career in cancer research, a career that might provide the breakthrough that humanity has been searching and hoping for all of these many centuries. Thus although you will never know it, you will have "been there" at the initial motivation of that person and thus indirectly present at the earliest genesis of the eventual great idea.

In the United States one in three women and one in two men will develop cancer in their lifetime. Dr Siddhartha Mukherjee, a medical oncologist, has written a definitive history of cancer. It may be one of the best medical books I have read. Complex but simple in terms of understanding. A timeline of a disease and those who waged the wars. In 1600 BC the first case of probable breast cancer was documented. In the thousands of years since, the Greek word, 'onkos', meaning mass or burden, has become the disease of our time. Cancer. The title of the book, is "a quote from a 19Th century physician" Dr Mukherjee had found inscribed in a library book that "cancer is the emperor of all maladies, the king of our terrors".

As a health care professional and as a woman who is six years post breast cancer, Cancer has played a big part in my life. I used to walk by the Oncology clinic, and quicken my pace. I used to give chemotherapy to my patients, before it was discovered that the chemo was so toxic that it needed to be made under sterile conditions and given by professionals who specialized in Oncology. Dr Mukherjee, wisely discusses cancer in the context of patients, those of us who suffer. After all it is because of the patients, the people who have gone before us, who have contracted some form of cancer, they are the base of this science.

Dr Mukherjee started his immersion in cancer medicine at the Dana Farber Cancer Institute in Boston. He relates the beginning of the study of ALL, Acute Lymphocytic Leukemia, by Dr Sidney Farber in 1947. Dr Farber, a pathologist at the time decided to change his focus and start caring for patients. He was given a medication to trial for ALL, and though most of his patients died, some survived to remission. This opened his world and with the help of Mary Lasker, and Charles E Dana, philanthropists, they opened one of the first clinics that specialized in cancer care and research, The Dana Farber Cancer Center. Dr Mukherjee gives us the timeline of ALL and lymphomas and the medications that turned into chemotherapy. The development of specific care for blood cancers and the emergence of AIDS and patient activism. He discusses the surgery for breast cancer. It was thought that the more radical the surgery the better the outcomes. We now know that lumpectomies have an excellent outcome. But, women before me had a radical removal of breast, chest tissue, lymph nodes and sometimes ribs. The lesson learned is that breast cancer is very curable now and all those men and women, the patients who suffered, gave us the answers and cancer care has moved on.

The onslaught of chemotherapies changed the face of cancer, and the 1970's served us well. In 1986 the first outcomes of cancer care were measured. Tobacco emerged as an addiction and soon lung cancer was a leading cause of death. Presidential Commissions ensued, politics entered the world of cancer, the war against cancer and the war against smoking. The Pap smear was developed, and prevention came to the fore. The two sides of cancer, the researchers and the physicians at the bedside, who often thought never the twain shall meet, recognized the importance of research to bedside.

The story of the boy 'Jimmy' from New Sweden, Maine, became the face of childhood cancer. The Jimmy Fund, a Boston Red Sox charity in Boston, is still going strong today. 'Jimmy' opened the door to the public for the need for money and research, and care for those with cancer. We follow Dr Mukherjee with one of his first patients, Carla, from her diagnosis through her treatment. He has given a face to cancer. We all know someone with cancer, those who survived and those who did not. Cancer prevention is now the wave of the future.

"Cancer is and may always be part of the burden we carry with us," says Dr Mukherjee. He has now written a "biography of cancer" for us, those without special medical knowledge. However, he does go astray in some discussions such as genetics. I have an excellent medical background, and found I was floundering at times. As I discovered,and Dr. Mukherjee agrees, our patients are our heroes. They/we withstand the horrors of cancer, and the horrific, sometimes deadly treatments. The stories of his patients make us weep, and the complex decision making about their care make him the most caring of physicians.

The 'quest for the cure' is the basis of all science and research, and Dr Mukherjee has written a superb tome in language that we can all attempt to understand. The biography of Cancer. Cancer may always be with us,Dr Mukherjee hopes that we outwit this devil and survive.

Causes For Cancer Biography

All patients begin as storytellers, the oncologist Siddhartha Mukherjee observes near the start of this powerful and ambitious first book. Long before they see a doctor, they become narrators of suffering, as Mukherjee puts it — travelers who have visited the “kingdom of the ill.”

Books of The Times: ‘The Emperor of All Maladies’ by Siddhartha Mukherjee (November 11, 2010)
Many doctors become storytellers too, and Mukherjee has undertaken one of the most extraordinary stories in medicine: a history of cancer, which will kill about 600,000 Americans by the end of this year, and more than seven million people around the planet. He frames it as a biography, “an attempt to enter the mind of this immortal illness, to understand its personality, to demystify its behavior.” It is an epic story that he seems compelled to tell, the way a passionate young priest might attempt a biography of Satan.

Mukherjee started on the road to this book when he began advanced training in cancer medicine at the Dana-Farber Cancer Institute in Boston in the summer of 2003. During his first week, a colleague who’d just completed the program took him aside. “It’s called an immersive training program. But by immersive, they really mean drowning,” he said, lowering his voice the way many of us do when we speak of cancer itself. “Have a life outside the hospital,” the doctor warned him. “You’ll need it, or you’ll get swallowed.”

“But it was impossible not to be swallowed,” Mukherjee writes. At the end of every evening he found himself stunned and speechless in the neon floodlights of the hospital parking lot, compulsively trying to reconstruct the day’s decisions and prescriptions, almost as consumed as his patients by the dreadful rounds of chemotherapy and the tongue-twisting names of the drugs, “Cyclophosphamide, cytarabine, prednisone, asparaginase. . . .”

Eventually he started this book so as not to drown.

The oldest surviving description of cancer is written on a papyrus from about 1600 B.C. The hieroglyphics record a probable case of breast cancer: “a bulging tumor . . . like touching a ball of wrappings.” Under “treatment,” the scribe concludes: “none.”

For more than 2,000 years afterward, there is virtually nothing about cancer in the medical literature (“or in any other literature,” Mukherjee adds.) The modern understanding of the disease originated with the recognition, in the first half of the 19th century, that all plants and animals are made of cells, and that all cells arise from other cells. The German researcher Rudolph Virchow put that in Latin: omnis cellula e cellula.

Cancer is a disease that begins when a single cell, among all the trillions in a human body, begins to grow out of control. Lymphomas, leukemias, malignant melanomas, sarcomas all begin with that microscopic accident, a mutation in one cell: omnis cellula e cellula e cellula. Cell growth is the secret of living, the source of our ability to build, adapt, repair ourselves; and cancer cells are rebels among our own cells that outrace the rest. “If we seek immortality,” Mukherjee writes, “then so, too, in a rather perverse sense, does the cancer cell.”

Mukherjee opens his book with the story of one of the founders of the hospital where he trained — Sidney Farber, a specialist in children’s diseases who began as a pathologist. In 1947, Farber worked in a tiny, dank laboratory in Boston, dissecting specimens and performing autopsies. He was fascinated by a sharklike species of cancer called acute lymphoblastic leukemia, which can move so fast that it kills an apparently healthy child within only a few days. A patient would be “brought to the hospital in a flurry of excitement, discussed on medical rounds with professorial grandiosity” and then sent home to die.

In the summer of 1947, a 2-year-old boy, the child of a Boston shipyard worker, fell sick. Examining a drop of the baby’s blood through the microscope, Farber saw the telltale signs of acute lymphoblastic leukemia, billions of malignant white cells “dividing in frenzy, their chromosomes condensing and uncondensing, like tiny clenched and unclenched fists.” By December, the boy was near death. In the last days of the year, Farber injected his patient with an experimental drug, aminopterin, and within two weeks he was walking, talking and eating again. It wasn’t a cure, only a remission; but for Farber it was the beginning of a dream of cures, of what one researcher called “a penicillin for cancer.”

The next year, Farber helped start a research fund drive around a boy who suffered from a lymphoma in his intestines, a disease that killed 90 percent of its victims. The boy was cherubic and blond, an enormous fan of the Boston Braves, and his name was Einar Gustafson. For the sake of publicity, Farber rechristened him Jimmy. That May, the host of the radio show “Truth or Consequences” interrupted his usual broadcast to bring his listeners into Jimmy’s hospital room to listen in as players on the Braves marched into Jimmy’s room and sang “Take Me Out to the Ball Game.”

By the summer of 1952, Farber had built an imposing new hospital, Jimmy’s Clinic. Soon, he was working on an even grander scale, with the help of an extraordinary socialite and medical philanthropist, Mary Lasker. (“I am opposed to heart attacks and cancer,” she once told a reporter, “the way one is opposed to sin.”) Mary and her husband, Albert, an advertising executive, joined forces with Farber. They wanted, as Mukherjee writes, “a Manhattan Project for cancer.” Together, through masterly advertising, fund-raising and passion for their common cause (“The iron is hot and this is the time to pound without cessation,” Farber wrote to Mary Lasker), they maneuvered the United States into what would become known as the war on cancer. Richard Nixon signed it into law with the National Cancer Act in 1971, authorizing the spending of $1.5 billion of research funds over the next three years.

In political terms, the war was well timed, coming at a time when America’s collective nightmares were no longer “It Came From Outer Space” or “The Man From Planet X,” but “The Exorcist” and “They Came from Within.” Mary Lasker called the war on cancer the country’s next moon shot, the conquest of inner space.

In scientific terms, however, the war was disastrously premature. The moon race had been based on rocket science. But in the early 1970s, there really wasn’t a science of cancer. Researchers still did not understand what makes cells turn malignant. Now that they were so much in the spotlight, and in the money, they fell into bickering, demoralized, warring factions. The “iconic battleground” of the time was the chemotherapy ward, Mukherjee writes, “a sanitized vision of hell.” Typically it was a kind of limbo, almost a jail, in which absolutely no one spoke the word “cancer,” the inmates’ faces had an orange tinge from the drugs they were given, and windows were covered with heavy wire mesh to keep them from committing suicide. “The artifice of manufactured cheer (a requirement for soldiers in battle) made the wards even more poignantly desolate,” Mukherjee writes.

“The Emperor of All Maladies” is a history of eureka moments and decades of despair. Mukherjee describes vividly the horrors of the radical mastectomy, which got more and more radical, until it arrived at “an extraordinarily morbid, disfiguring procedure in which surgeons removed the breast, the pectoral muscles, the axillary nodes, the chest wall and occasionally the ribs, parts of the sternum, the clavicle and the lymph nodes inside the chest.” Cancer surgeons thought, mistakenly, that each radicalization of the procedure was progress. “Pumped up with self-confidence, bristling with conceit and hypnotized by the potency of medicine, oncologists pushed their patients — and their discipline — to the brink of disaster,” Mukherjee writes. In this army, “lumpectomy” was originally a term of abuse.

Meanwhile, more Americans were dying of cancer than ever, mainly because of smoking. Back in 1953, the average adult American smoked 3,500 cigarettes a year, or about 10 a day. Almost half of all Americans smoked. By the early 1940s, as one epidemiologist wrote, “asking about a connection between tobacco and cancer was like asking about an association between sitting and cancer.” In the decade and a half after Nixon declared his war on cancer, lung cancer deaths among older women increased by 400 percent. That epidemic is still playing itself out.

Mukherjee is good on the propaganda campaign waged by the tobacco companies, “the proverbial combination of smoke and mirrors.” As one internal industry report noted in 1969, “Doubt is our product, since it is the best means of competing with the ‘body of fact.’ ” This episode makes particularly interesting reading to anyone following the current propaganda campaigns against the science of climate change.

Meanwhile, those who studied the causes of cancer in the laboratories and those who treated it in the clinics were not always talking to each other. As Mukherjee puts it, “The two conversations seemed to be occurring in sealed and separate universes.” The disease was hard to understand either intellectually, in the lab, or emotionally, in the clinic. In the lab, because it is so heterogeneous in its genetics and its migrations in the body. In the hospital, because its course is horrible and so often slow, drawn out. When it comes to cancer, Mukherjee writes, “dying, even more than death, defines the illness.”

Mukherjee stitches stories of his own patients into this history, not always smoothly. But they are very strong, well-written and unsparing of himself: “Walking across the hospital in the morning to draw yet another bone-marrow biopsy, with the wintry light crosshatching the rooms, I felt a certain dread descend on me, a heaviness that bordered on sympathy but never quite achieved it.”

The heroes of the last few decades of this epic history are Robert Weinberg, Harold Varmus, Bert Vogelstein and the other extraordinary laboratory scientists who have finally worked out the genetics of cancer, and traced the molecular sequence of jammed accelerators and missing brakes that release those first rebel cells. As James Watson wrote not long ago, “Beating cancer now is a realistic ambition because, at long last, we largely know its true genetic and chemical characteristics.” We may finally be ready for war.

As a clinician, Mukherjee is only guardedly optimistic. One of the constants in oncology, as he says, is “the queasy pivoting between defeatism and hope.” Cancer is and may always be part of the burden we carry with us — the Greek word onkos means “mass” or “burden.” As Mukherjee writes, “Cancer is indeed the load built into our genome, the leaden counterweight to our aspirations for immortality.” But onkos comes from the ancient Indo-European nek, meaning to carry the burden: the spirit “so inextricably human, to outwit, to outlive and survive.” Mukherjee has now seen many patients voyage into the night. “But surely,” he writes, “it was the most sublime moment of my clinical life to have watched that voyage in reverse, to encounter men and women returning from that strange country— to see them so very close, ­clambering back.”
