Like most treatments, radiation therapy for prostate cancer has its pros and cons.

Disadvantages are that radiation can also result in normal cells being killed and produce other short term side effects like sexual dysfunction, urinary problems and bowel problems.

External beam radiation therapy points a concentrated beam at the cancer cells from outside the body.

This treatment is also beneficial because it usually stops the cancer from spreading elsewhere and can prevent future cancer in other parts of the body.

It's important for potential patients to be aware of the negative side effects that can result from radiation therapy for prostate cancer. One of the downsides of radiation is that it can also kill some normal cells in the process of destroying malignant cells. Doctors will naturally try to minimize the amount of normal cells affected.

In addition to this, there are several negative short term side effects that can result from radiation. Sexual dysfunction is a common problem experienced by many men undergoing this treatment, and primarily includes difficulty achieving and maintaining erections. Problems reaching orgasm and a temporary reduction in the amount of sperm can also result from radiation.

Urinary problems are also fairly common after radiation therapy. Feelings of burning and discomfort while urinating can often last for over a month. Frequent urination is another common side effect. These issues are uncomfortable, but usually clear up on their own over time.

Radiation therapy for prostate cancer can also result in some mild bowel problems. Issues like bloody stools, small amounts of excrement, and diarrhea are the most common issues patients experience. Sometimes a doctor will prescribe a medication to ease the discomfort, but the bowel problems that result from radiation also usually clear up on their own.
