I would like to share my personal view on prostate cancer screening : my father was found 'positive' at around ~61 yrs. He evaluated the offered treatments and opted for 'internal radiation' : a bunch of radio-active pellets are implanted in the prostate.

I heard from him one of the pellets went 'missing' and was assumed to be 'wandering'.

At 63 yrs, he developed acute leukemia and basically died within a week.

I am not going to research and pursue this, but I am very bitter.
