A potentially effective treatment for localized prostate cancer, radiation therapy can be used on its own or in combination with surgery or hormone therapy. The most common form is external beam radiation therapy (EBRT), which is similar to a routine X-ray. High-energy beams, which are generated by an external machine (linear accelerator) and aimed directly at the prostate gland, can shrink a tumor and destroy cancerous cells with minimal effect on surrounding healthy tissues. Typically, EBRT is administered five times per week for four to nine weeks.
Because EBRT is a localized treatment, its side effects usually appear in the specific area of the body targeted. When administered for prostate cancer treatment, EBRT often causes urinary and bowel side effects during the second or third week. Most are temporary and gradually improve within several weeks after treatment is completed. In the meantime, any discomfort can usually be managed with medication and supportive care.
Possible side effects of EBRT for prostate cancer
When undergoing EBRT for prostate cancer, some patients experience:
- Urinary urgency
- More frequent urination
- Difficulty starting urination
- Burning sensations during urination
- A weak or slow urine stream
- More frequent bowel movements
- Smaller and softer stool
- Occasional diarrhea
- Rectal irritation
- A flare-up or worsening of hemorrhoids
Additionally, many patients experience general fatigue during prostate cancer treatment. However, most feel well enough to continue their normal daily activities.
