A pretty sobering fact is that by the time us blokes reach 80, half of us are likely to have prostate cancer (although we won't all know it).
It's a gland with a seeming inbuilt self-destruct mechanism and it's one of the reasons women live significantly longer than men.
As the second most prevalent carcinomic malignancy (after lung cancer) it seems to me that very few resources are devoted into research into it, simply because most victims are elderly men.
