Study links five infectious agents to half a million new cancers annually
A recent analysis in *The Lancet Global Health* found that over half a million new cancer cases each year are tied to specific infections: H. pylori, HPV, HBV, EBV, and HCV. While aging causes most cancers, these pathogens play a significant role in about 4.5% of diagnoses globally. The findings underscore a clear path for prevention through vaccination and early treatment.

The architecture take
I used to think of cancer as a lottery, mostly tied to genetics or just bad luck with aging. But this data hits different: 610,000 new cancer cases globally in 2018 were preventable because they stemmed from five common infections. H. pylori and HPV led the pack, causing stomach and cervical cancers, respectively. That's a huge number. It means a significant chunk of cancer risk isn't just random cellular breakdown; it's inflammation, persistent immune activation, and cellular damage from known pathogens. Vaccinations for HPV and HBV, plus early detection and treatment for H. pylori and HCV, suddenly feel like primary longevity tools. My takeaway: it's not just about what you put in your body, but what you keep out, and how well your immune system is prepped for it.
