Sorry to hear that but much agreedI've had testicular cancer which migrated near to my kidney after having had the offending testicle removed. Since my other testicle was atrophied from birth, I'm infertile but unfortunately suffer from low testosterone, too. I haven't had shots yet but will soon.
Anyway, in all this time my foreskin hasn't been an issue. So the idea that circumcision negates cancer is probably made up by circumcisers scouting their next victim/client.
