A common prostate cancer treatment is radiation therapy. There are two types of radiation therapy: internal or interstitial radiation and external radiation. Interstitial radiation, known as brachytherapy is radiation that is administered internally to the affected tissue. External radiation, or EBRT, is applied from the outside using the maximum amount of radiation possible without damaging surrounding organs and tissue.

The hormone testosterone is responsible for the growth of the male sex organs and therefore contributes to the growth of cancer in the prostate. A non-invasive prostate treatment is to cease the production of testosterone, thus stopping the continued growth of cancerous cells. Tests have shown that after this prostate treatment is complete, testosterone levels generally return to normal or almost normal.

Chemotherapy is a prostate cancer treatment generally used when alternative treatments like prostate surgery have failed. It is used only for cancer that is very far along and has spread to other areas of the body. Chemotherapy utilizes extremely toxic chemicals that kill the cancerous cells.

The concept of prostate surgery is to get rid of the cancerous gland itself. This prostate treatment is only helpful if the cancer is confined to the prostate. Prostate surgery can often be radical, involving not just the removal of the gland itself, but the surrounding veins and nerves.
