Chemotherapy may be used for prostate cancer that has spread and no longer responds to hormone therapy. It is not a standard treatment for early prostate cancer and is unlikely to cure a patient of cancer. Chemotherapy may also be an option for cancers that don't respond to hormone therapy. This treatment is used to slow the growth of cancer and reduce symptoms to improve a patient’s quality of life.

Chemotherapy uses anti-cancer drugs injected into a vein or given by mouth. These drugs enter the bloodstream and move throughout the body to destroy cancer cells that have spread away from the primary tumor.

Chemotherapy can be administered in a clinic, at the doctor's office or at home.
