KEYPOINTS
- 01
Raza argues that age-adjusted cancer mortality is essentially where it was in 1930
Peter usually says cancer mortality hasn't changed since about 1970. Raza goes further. She says the roughly 27–30% decline over the last 30 years followed a 30-year rise driven by smoking, so the fall mostly tracks the drop in smoking. In her words, 'otherwise we are really at square one.' She compares herself to Nietzsche's man with a lamp at noon, except she is 'looking for an adult in the room.'
- 02
Most cures still come from 'slash, poison, burn,' and only in early disease
Raza's breakdown: of newly diagnosed cancers, about 68% are cured, overwhelmingly with surgery, chemotherapy and radiation. The 32% who present with advanced disease mostly can't be cured with those same tools. She takes this as the best evidence that the only reliable lever is catching cancer early. Some of the first chemotherapy agents came out of chemical weapons research, and she gave all three of the original drugs to her own husband.
- 03
Real breakthroughs are real but rare
Gleevec for CML and GI stromal tumors proved targeted therapy can work, but those are rare cancers, and Peter doubts it has moved overall mortality even 1%. Melanoma survival is dramatically better with checkpoint inhibitors. Still, Raza estimates all such successes together account for under 10% of cancers. Her question is whether they reflect the 'quarter of a trillion dollars' invested. She is clear that this research should continue.
- 04
95% of experimental cancer drugs fail, and Raza says many of the 5% shouldn't have passed
In her account, the 'winners' often extend survival by a few months in only 20–30% of patients. Approvals often rest on progression-free survival: if the tumor isn't seen to grow for an extra two and a half months but the patient dies at the same time, the drug can still be approved and earn billions. Peter adds that a 'partial response' has a somewhat arbitrary definition and that durability is rarely discussed.
- 05
The core scientific problem, in her view, is the preclinical model
Raza blames the failure rate on reductionist testing platforms such as cell lines, 2D and 3D cultures, and genetically engineered or immune-compromised mice. She says she supports animal research for biology, but not for drug development, because what a drug does in a mouse is only true for mice. She would not even rely on animals for safety. She points to the FDA's phase zero design, which starts humans at 1/500th of a dose and escalates.
- 06
New drugs often cost far more for small gains, with ruinous consequences for patients
Her figures: 42% of newly diagnosed cancer patients will be financially ruined by the second year, and 50% of women with breast cancer are pursued by collection agencies. Peter recalls that Avastin in metastatic colorectal cancer added about four months of median survival at roughly $100,000, which led some publicly funded systems to rely on quality-adjusted life years. Peter flags that his Avastin details may not be exact.
- 07
Good intentions slowly produced a broken system
Raza uses the frog-in-slowly-heating-water image: each step began with good intentions. Peter adds that publication as a promotion metric fuels a 'cottage industry' of low-quality journals and irreproducible studies. He also says that by his own analysis from about five years earlier, slightly more than half of global oncology research money ran through the NCI after Nixon's war on cancer, though he notes he could be a little wrong.
- 08
Her proposed solution is aggressive early detection, monitored continuously
Raza argues that mammograms and PSA failing on their own doesn't prove early detection fails. She wants genomics, transcriptomics, proteomics, metabolomics and imaging combined with AI, with up to '50 tests if we have to,' read continuously rather than once a year. Peter frames it as three rules: don't get cancer, screen smartly, and treat when tumors are in the millions rather than billions of cells. He estimates lifestyle changes could cut cancer risk 30–50%, based on his reading of the literature.
- 09
Powerful late-stage therapies should move earlier
She calls current treatment 'paleolithic,' quoting the line about beating a dog with a baseball bat to get rid of its fleas. She notes that whole industries exist just to manage CAR-T side effects. She says such therapies should be developed, but used when tumor burden is low.
EXAMPLES
- 01
Andrew, 22, and the book The First Cell
Her daughter Shahzad's best friend developed arm weakness, was quadriplegic within hours, and had a 9 cm unresectable glioblastoma. His first words were 'just call Azra… she will cure me.' Their helplessness pushed her to write after years of turning down literary agent John Brockman.
- 02
'Seven and three' for AML since 1977
Raza still uses cytarabine plus daunorubicin. Five-year survival rose from about 10% to about 26%, which she credits to better antibiotics and transfusions, not new drugs. A liposomal version for patients aged 60–75 costs $45,000 versus $5,000, approved on a 3.7-month median survival gain in selected patients.
- 03
Karachi in the early 1970s
Raza was born and raised in Pakistan and entered science through medicine. She saw patients arrive by donkey cart with fungating tumors. Her first patient, a young woman with AML and a large spleen, made her favor studying liquid tumors, which can be sampled repeatedly.
- 04
Harvey Preisler's acceptance
Her husband, head of the Roswell Park leukemia program, died in 2002 after a five-year battle; their daughter was four at diagnosis. On hearing his diagnosis he said, 'I'm glad it's me and not you or Shahzad.' Raza admits kicking doors and crying while he called it 'the luck of the draw.'
- 05
A 60,000-sample tissue bank
Since 1984 Raza has collected serial blood, marrow and germline samples, doing every marrow herself. She hopes to trace pre-leukemia to leukemia, find early biomarkers, and find the 'first cell.'
OTHER RELEVANT
- 01
Read 'approved' and 'progression-free survival' skeptically
When a new drug is touted, ask about median overall survival, what fraction of patients benefit, and whether the gain is weeks or months. Raza's 3.7-month example shows how far headlines can outrun benefit.
- 02
Smarter screening beats single tests
Peter points to PSA velocity, PSA density and 4Kscore over PSA alone, citing his Ted Schaeffer episode, and to his Raj Attariwala episode on mammography's limits. Raza highlights an FDA-approved fingertip-blood PSA chip and Toshiba's claim of 13 cancers from one drop of blood for $180 in four hours.
- 03
Treat liquid biopsies as promising but early
Both are optimistic about multi-cancer blood tests such as Grail, which Raza says was in phase 2 with about 30 cancers. Peter avoids predicting a timeframe and wants regulatory milestones first.
