Key fact

NCI states that for some cancers, finding and treating the cancer early does not improve the chance of a cure or help a person live longer.

The short answer

Azra Raza is a leukemia specialist who treats myelodysplastic syndromes and acute myeloid leukemia, and who cared for her husband through his own leukemia. Her 2019 book argues that decades of research into late-stage treatment have delivered small gains at enormous human cost, and that the field should be looking for the first cancer cell instead. The argument is serious and the case histories are unsparing. The federal evidence on early detection is more complicated than the book's framing suggests.

  • NCI states that for some cancers, finding and treating the cancer early does not improve the chance of a cure or help a person live longer.

  • NCI names mammography and sigmoidoscopy with fecal occult blood testing among the screening tests shown to reduce cancer deaths.

  • Overdiagnosis means finding cancers that would never have caused symptoms; NCI cites estimates of 19% of screen-detected breast cancers and 20% to 50% of prostate cancers.

  • NCI states the only reliable way to know whether a screening test reduces deaths is a randomized trial showing a reduction in cancer deaths.

The full explanation.

What the book is

Azra Raza is a professor of medicine at Columbia. She has spent her career on myelodysplastic syndromes and acute myeloid leukemia. In those two diseases progress has been slow, and most patients die of the illness. She has also kept a tissue repository of her own patients' samples for decades.

The First Cell: And the Human Costs of Pursuing Cancer to the Last is not a history and not a memoir, though it contains both. It is a sustained argument, made through the deaths of specific people she treated.

A death stated plainly. Raza's husband, the oncologist Harvey Preisler, died of leukemia. She writes about caring for him as both wife and doctor, and she does not hold it back as a reveal.

Her thesis is straightforward. Huge effort goes into treating cancer once it is advanced. For many cancers, the return on that effort has been small. Meanwhile almost nothing goes into finding the first cancer cell. That is the point at which the disease might be stopped. She wants the money, the talent and the attention moved.

The book is angry. The anger is aimed at a research system, not at individual doctors. She counts herself among the accused.

What's inside

The book runs to 368 pages in the Basic Books edition, published 15 October 2019, with notes and references.

Its structure is unusual. Most chapters are built around a single patient, named or pseudonymous, followed from diagnosis to death. Raza gives the clinical course and the treatments tried. She gives what each cost the person in suffering, and what it bought in time. The build-up is deliberate. By the fifth or sixth chapter, the reader has stopped expecting a good outcome.

Between those chapters she makes the argument. She writes about the biology of MDS and how it turns into AML. She writes about why animal models have carried over so poorly into human benefit. She writes about trials that produce statistically significant results with little meaning for patients. And she writes about the money in drug development.

There is also a chapter on her husband's illness and death. It is the emotional centre of the book, and the hardest section to read.

The final part is constructive. She sketches what a research programme aimed at the first cell would look like. Tissue repositories. Sampling people at risk over time. And a shift in what counts as a question worth funding. She acknowledges the tools for it largely do not exist yet.

Where it is strongest

The case histories are extraordinary. Raza refuses the usual grammar of cancer writing. In that grammar, suffering is squeezed small and outcomes are described in the passive voice. She writes what mucositis looks like. What a failed transplant does to a family. What a fourth-line treatment costs a person in their last months.

She is also credible on her own specialty. MDS and AML are where her claim is strongest, and NCI's own summary supports the picture. MDS transforms to AML when blasts reach 20%. The acute leukemic phase is less responsive to chemotherapy than de novo AML. The only potentially curative option is stem cell transplant. And the gain from azacitidine in higher-risk disease is a median overall survival of 24 months against 16. Those are real numbers and they are small.

Her handling of animal models is another strength. She explains why a mouse cured of an implanted tumor tells you less than it seems to, and why the pipeline keeps producing drugs that work in that setting and not in people. It is a technical point made accessible without being softened.

The argument about incentives is worth taking seriously too. A research system that rewards small gains in advanced disease will produce small gains in advanced disease. Nobody planned it that way.

Where to read it carefully

The generalisation from MDS and AML to cancer as a whole is the weak joint. Her diseases are among the hardest in oncology. Late-stage treatment produced lasting cures in Hodgkin lymphoma, testicular cancer, chronic myeloid leukemia and childhood leukemia. Carrying the same gloom over to them would be wrong. The book largely leaves those cases out.

The early detection argument is also treated as more straightforward than it is. Finding cancer earlier is not automatically better. The book does not really take on lead-time bias, length bias or overdiagnosis. Those are the very reasons early detection sometimes fails to save lives.

Selection matters as well. Chapters built around patients who died produce a book in which patients die. That is an honest reflection of her clinic and a partial reflection of oncology.

Her proposals are also thinner than her diagnosis. Sampling healthy people over years, at scale, is costly and slow, and it raises hard ethical questions. The book waves at those problems rather than working through them. That is a fair limit for a book of this kind, but it means the constructive chapters carry less weight than the critical ones.

Finally, a reader in treatment should know what they are picking up. Nothing here is meant to reassure, and the descriptions of end-stage disease are graphic.

What early detection can and cannot do

This is where the federal material adds what the book leaves out.

NCI's screening overview states the purpose plainly. Screening looks for cancer before a person has symptoms. Early detection may make a cancer easier to treat or cure. It then states the limit just as plainly. For some cancers, finding and treating the cancer early does not improve the chance of a cure. Nor does it help the person live longer. Fast-growing cancers may already have spread by the time any test could find them.

NCI also says all tests carry possible risks. Problems from the procedure itself. False-positive results, which cause worry and more testing. And false-negative results, which can delay diagnosis if symptoms appear later.

NCI names some tests as proven. Among those shown to reduce cancer deaths are mammography for breast cancer, and sigmoidoscopy with fecal occult blood testing for colorectal cancer. That list is short by design, because the standard is high.

NCI's discussion of screening statistics explains why. Lead-time bias makes survival look longer when a diagnosis is simply made earlier. Take a man diagnosed at 60 rather than 67, who dies at 70 either way. He has better five-year survival and not one extra second of life. Length bias means screening preferentially catches slow-growing cancers. Overdiagnosis is the extreme of that, and NCI cites estimates of 19% of screen-detected breast cancers and 20% to 50% of prostate cancers. NCI's conclusion is blunt. The only reliable way to know whether a screening test reduces deaths is a randomized trial showing a drop in cancer deaths.

That is not a refutation of Raza's argument. It is the specification her argument has to meet. For the details, see cancer screening overview and overdiagnosis.

Where multi-cancer blood tests actually stand

The book was published just as multi-cancer early detection tests began to be sold, and readers often connect the two.

NCI's position is specific. FDA-cleared liquid biopsies exist for people who already have a cancer diagnosis. MCED tests meant to screen people without symptoms remain investigational. They are not approved for routine clinical use.

NCI lists the open questions. Who should be tested, and with which test. How the tests perform across different racial, ethnic and socioeconomic groups. Whether take-up would pull people away from screening that is already proven. And, most of all, whether these tests reduce cancer deaths at all. It names two specific harms. False positives lead to invasive and costly procedures that find nothing. And overdiagnosis picks up slow-growing cancers that would never have caused symptoms.

NCI has been building the randomized trials needed to answer the death-rate question. It does not treat the tests as settled. Until that reads out, a marketed MCED test is a research question being sold as a service.

So the honest version of Raza's argument is this. Finding cancer at the first cell would change everything, if the finding changed what happened next. Nobody has yet shown that it does. That is a reason to fund the work, not a reason to buy the test. Raza's argument is that treating late disease absorbs the money early detection would need.

For where these tests stand in detail, see multi-cancer early detection blood tests.

Who this book suits

It suits readers who want to know what advanced blood cancer actually involves, told plainly. It suits people interested in how research priorities get set. It suits clinicians and students, and it has been widely assigned for that reason.

It suits readers of Mukherjee and Kalanithi who want the other side of the case. It works against any book that treats cancer progress as a steady upward line.

It suits a reader who is already angry about how cancer is discussed and wants that anger given shape by someone qualified to hold it.

It does not suit someone in active treatment for a blood cancer, or a caregiver in the middle of one. The case histories are not written to be survivable reading in that position. It also does not suit a reader who wants a balanced account of cancer research. The book is an argument, and says so.

Common questions

What is The First Cell arguing?

That cancer research has concentrated on treating advanced disease, that the gains from doing so have often been marginal, and that resources should move toward detecting the earliest cancer cells. Raza makes the case as a practising oncologist rather than as a policy analyst.

Is she right that early detection is better than late treatment?

Partly, and it depends on the cancer. NCI states that for some cancers, finding and treating them early does not improve the chance of cure or help the person live longer, and that fast-growing cancers may not benefit from screening. Early detection is powerful for some cancers and has not been shown to help for others.

What is overdiagnosis?

Finding a cancer that would never have caused symptoms in that person's lifetime. NCI describes it as the extreme of length bias and cites estimates that 19% of screen-detected breast cancers and 20% to 50% of prostate cancers are overdiagnosed.

Are multi-cancer blood tests available?

Not as approved screening tests. NCI's position is that FDA-cleared liquid biopsies exist for people already diagnosed with cancer, and that MCED tests for screening healthy people remain investigational with no evidence yet that they reduce cancer deaths.

Is the book fair to cancer research?

It is one-sided by design. It says little about the cancers where late-stage treatment did transform outcomes, such as Hodgkin lymphoma, testicular cancer or chronic myeloid leukemia, and it does not seriously engage with why finding cancer earlier sometimes fails to help.
