Cancer
The argument about what causes cancer changes nothing about how to lower your risk. After a diagnosis, the same argument changes everything — which is why this page keeps asking where you are standing.
Why it matters
Cancer attracts more confident theory than any other subject in our library. Knowing which parts of the argument affect a decision, and which are settled enough to act on today, separates using this from being sold something.
Key insights from this synthesis
- The prevention basics survive every theory war about what causes cancer. Both sides recommend the same things.
- Alcohol is the clearest modifiable cause here — the same risk category as tobacco, with no safe level established.
- The most qualified alcohol researcher in our library is the one who refuses to reduce it to a slogan.
- One popular abstinence figure matches the length of the programme selling it, and has no independent evidence behind it.
- For early prostate cancer, surgery, radiotherapy and monitoring showed similar long-term survival. The choice is about side effects, not survival.
