- the_af 4y agoThe news here is not that air pollution is linked to cancer, but about what the underlying mechanism could be: > "However, the biological basis for how air pollution causes cancer has remained unclear. Unlike smoking or sun exposure, which directly cause DNA mutations linked to lung and skin cancer, air pollution does not cause cancer by triggering such genetic changes."
- Gatsky 4y agoYeah, PM2.5 is listed as a known carcinogen, and there is strong epidemiological data supporting the link between respiratory tract cancers and pollution. This work provides a mechanism for how this happens, where air pollution promotes the transition of cells into a malignant state, without directly damaging DNA.
- hammock 4y agoYes. At some point though we stopped caring, and moved onto different “pollutants”
- dennis_jeeves1 4y agoYes, but only the older people who have good memory, or the young people who bothered to keep themselves informed by reading some 'history' or talking to smart older people.
