Prostate brachytherapy is a form of radiation therapy used to treat prostate cancer. Prostate brachytherapy involves placing devices containing radiation in the prostate gland close to the cancer cells.Permanent prostate brachytherapy involves placing radioactive seeds in the prostate gland permanently, where they slowly release radiation.The goal of prostate brachytherapy is to place the radiation close to the cancer cells, where the radiation can kill the cancer cells while causing less damage to healthy tissue nearby.After prostate brachytherapy, you can expect some pain and swelling in the perineum where the radiation needles were inserted. You may find relief by placing an ice pack over the area or taking acetaminophen (Tylenol, others). Tell your doctor if these measures aren't controlling your pain.You can resume normal activities when you feel up to it. Avoid strenuous activity, such as running, or activities that may irritate the perineum, such as riding a bike, until the area where the radiation was inserted is no longer tender.



These are the commoner risks. There may be other unusual risks that have not been listed here. Please ask you surgeon if you have any general or specific concerns.There are risks associated with any anaesthetic, you may have side effects from any drugs used.
