I'll use this thread to repeat something I mentioned in the Tackle 2019 Conference thread, which is of relevance to black men (twice the incidence of PCa), or in this case, their boys. Professor Tim Oliver presented some findings of his own on causes of PCa, and some causes can be traced back to puberty. One in particular is a lack of Vitamin D during puberty, caused mainly by lack of playing outdoors. However, there's another cause of lack of Vitamin D, and that's having much darker colour skin in a non-equatorial climate, because the Vitamin D generated in sunlight will be far too low even if they do play outdoors. I raised this with Tim Oliver after his talk, asking if it might be why black men have twice the incidence of PCa. The answer is that no one knows, but it's a plausible hypothesis - I'm not the first person to suggest the connection.
So if you are the parent of black boys going through puberty in a non-equatorial climate like the UK, you might want to ensure they are not deficient in Vitamin D.
[and if you are the parent of white boys going through puberty in the UK, make sure they play outside in the sun.]
