Radiation therapy is a treatment to destroy cancer cells or shrink tumors. One type of radiation therapy is brachytherapy (say "bray-kee-THAIR-uh-pee"). It puts the radiation source into your body, either inside the tumor or next to it.
Brachytherapy may be used to treat prostate cancer. You may have a low-dose or high-dose treatment.
The area where you had radiation may be sore for a while. You may also have some swelling. It's normal to have some blood in your semen.
Most side effects go away after treatment ends. Side effects include trouble or pain when urinating and diarrhea. But you may feel very tired for 4 to 6 weeks after your last treatment. Tell your doctor if you have problems with a specific side effect.
If you have high-dose-rate treatments, you may need to stay in the hospital until your treatments are finished.
Your doctor will tell you if you need to keep children and pregnant people at a distance for any amount of time because of the radiation you were given.
Your doctor may give you instructions on when you can do your normal activities again, such as driving and going back to work.
Radiation treatment uses high-energy rays or radioactive material to kill cancer cells or to keep them from growing.
In internal treatment, your doctor puts an implant of radioactive material into your body. It is placed into or near the cancer so it can kill the cancer cells near it. The material may be left in place or taken out later. The treatment normally does not make your body radioactive. Your doctor will tell you if you can get close to people without exposing them to radiation. Internal treatment is also called brachytherapy (say "bray-kee-THAIR-uh-pee").
The length of treatment depends on the type of cancer you have and the type of radiation. The treatment itself is painless. But it can cause some side effects like fatigue, nausea, vomiting, and diarrhea. Areas inside your body can get sore. Most side effects usually go away after treatment ends. But you may feel very tired for 4 to 6 weeks after your last treatment. Talk to your doctor about ways to treat the side effects.
