Masturbate can cause testis and penis cancer?

It does not. Forgive my frankness. Whoever told you this is either a fool or a liar. If this is a "spiritual advisor", you'd do well simply to ignore this person and everything else they tell you. Being a young man is difficult enough without this cruel, evil counsel. Enjoy being a man, think about something nice rather than internet trash, and be discerning. Best wishes.
No worries. . No. But keep it up, you might prove me wrong.
