Similarly, a diagnosis of in situ prostate cancer means you'll have less risk of dying[1] over the next ten years compared to the rest of your age and race group. Totally not because men who catch these cancers early have good health insurance, regularly see their doctor, and keep up with screening procedures, plus all the other behaviors associated with those personality types. [1] If you look at the U.S. national statistics, net cancer survival rates top out at 100%. That's because their algorithm doesn't allow any negative values for risk. I think that's enforcing a belief on the data, so I've always calculated it differently. People diagnosed with in situ prostate cancer, in situ testicle cancer, and (IIRC) in situ melanoma all have better survival chances than their peers. Unsurprisingly, all are screenable and easily treated if caught early.
