It sounds like increased lifespan for men is the reason for the rise in cases.
If we stop other things from killing us, something else will. We are rather good at solving many many things that might kill us. So those that are left claim larger share.
Better diagnosis, us breathing/drinking/eating ever more polluted things probably doesn't help either
increased rate of diagnosis. it's always been there.
I’m sure that’s most of it - but I’d wager the incidence rate over the long term is increasing as well given diet and exposure to pollution/toxins
