Not so uncommon where I live. BTW, baby girls ALSO have ovaries, and they use talc for prolonged periods of time.
I also use talc in my groin. Not often, but still. Prostate cancer is not a concern for older males (we all develop it some time), but testicular cancer is a thing (mostly in children)
I’m sorry? What?
Prostate cancer is definitely a concern in males, and in no-way is it expected or an inevitability.
I remember reading somewhere that if you biopsied those that died of 'old-age' then it would be present in some form. So it's not a question of if, but when, and when, whether it'll be the thing that gets you before something else gives out.
An urologist whom I helped with typesetting of his PhD thesis (in LaTeX, funny guy) told me once that in patients over 70, basically everyone has some cancerous cells in his biopsy samples, but that these usually aren't actually dangerous to the patients.
Prostate cancer, as others have mentioned, is guaranteed, like death. But it is not something that affects most men's life beyond the worry of getting it.
Going offtopic: Colorectal cancer is a more pressing matter for older adults. Correct Screening saves lives.
