Radiation Therapy for Prostate Cancer

Possible Side Effects of Radiation for Prostate Cancer

• An occasional side effect reported from radiation is mild fatigue. This usually starts in the middle of treatment and may last a few weeks after treatment ends.
• Urinary frequency and discomfort on urination are common side effects of both external and internal radiation.
• Bowel irritation is another common side effect.
• Impotence is also a possible side effect of any treatment for prostate cancer. Fortunately, many patients who receive radiation therapy for prostate cancer are able to maintain sexual function.
• Don't be shy about talking to your doctor about your sex life. If you are having problems, talk to your doctor or oncology nurse. He or she may be able to suggest remedies or prescribe medication.
• External beam radiation may cause mild skin irritation. Clean the area regularly with mild soap and warm water.
• Some side effects can be controlled with medications and changes to your diet. Tell your doctor or nurse if you experience any discomfort so they can help you feel better.
