(1) Radiation therapy to kill cancer cells and can be done in two ways such as Radiation that comes from outside of your body (external beam radiation) and Radiation placed inside your body (brachytherapy). (2) Hormone therapy to stop your body from producing the male hormone testosterone. (3) Surgery to remove the prostate that involves removing the prostate gland (radical prostatectomy), some surrounding tissue and a few lymph nodes. (4) Freezing prostate tissue that involves freezing tissue to kill cancer cells. Small needles are inserted in the prostate using ultrasound images as guidance. A very cold gas is placed in the needles, which causes the surrounding tissue to freeze. (5) Heating prostate tissue using ultrasound that uses powerful sound waves to heat prostate tissue, causing cancer cells to die. (6) Chemotherapy that uses drugs to kill rapidly growing cells, including cancer cells. Chemotherapy can be administered through a vein in your arm, in pill form or both.

Masturbation is part of people's sexual repertoire. If these findings hold up, then it's perfectly reasonable that men should be encouraged to masturbate."
