Hi im 15 and i usually masturbate once every 2 days. I have always been a little paranoid and i was just wondering if i have testicular cancer. I have a tiny, tiny lump at the back of my testicle, next to my epididimis or whatever. Im not sure if it is cancer because it is right near that tube.
I read a leaflet and how to check yourself and thats how i discovered it. Thanks for all your help.
