Does sunscreen enter your bloodstream and weaken cancer defenses?

[Gary C]

What's True
Some chemical sunscreen ingredients can be absorbed through the skin and detected in blood. That part of the claim is based on real studies by FDA researchers, published in JAMA in 2019 and 2020.

What's False
However, those studies did not show that sunscreen causes cancer, damages the immune system or removes the body's cancer defenses. The 2020 JAMA study explicitly stated that its findings did not mean people should stop using sunscreen.
