The Claim

Modern humans have an elevated lifetime cancer risk of approximately 40%, potentially due to declines in adrenal androgens like DHEAS with age, which may disrupt a proposed tumor suppression mechanism, though this hypothesis remains untested.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

As people get older, their bodies might produce less of certain hormones, and this could make them more likely to get cancer over their lifetime, but scientists haven't proven this yet.

What the research says

1 study

  1. Study: A lex naturalis delineates components of a human-specific, adrenal androgen-dependent, p53-mediated ‘kill switch’ tumor suppression mechanism

    The study backs up the idea that lower levels of certain hormones as we age might explain why humans have a high cancer risk, by showing how these hormones help control tumors in our bodies.
