Treating Prostate Cancer

Radiation Therapy

  • Also known as "irradiation" or "radiotherapy," radiation therapy involves using high-energy x-rays to destroy cancer cells and shrink tumors.
  • In the early stages of prostate cancer, radiation therapy may be used instead of surgery, or it may be used after surgery to kill remaining cancer cells.
  • In the case of advanced prostate cancer, radiation therapy may be given to relieve pain or other problems.
  • "External beam radiation" therapy may be directed at the body in short daily sessions given over many weeks.
  • For localized prostate cancer, tiny radioactive "seeds," called "implant radiation" or "brachytherapy," may be placed inside the tumor.

Potential Side Effects of Radiation Therapy for Treating Prostate Cancer

  • The high-energy x-rays aimed at the cancer can also affect healthy cells.
  • May cause some side effects, including diarrhea, sometimes with blood in the stool, and cramping.
  • Other side effects may include inflammation of the bladder, blood in the urine, and frequent or urgent urination.
  • In some cases, bowel function does not return to normal after treatment.
  • Can also cause fatigue (extreme tiredness), which usually does not last more than a month or two after treatment.
  • Many side effects can be managed with medicines or special diets, so be sure to discuss these with your doctor or nurse.
