Internal Radiation Therapy
What is internal radiation therapy? Internal radiation therapy, also called brachytherapy, is a type of radiation to treat cancer. The source of radiation is placed in your body or on an area of your body close to the tumor. It is used to shrink the tumor or kill the cancer cells. Brachytherapy may be used with other treatments such as external radiation therapy, medicines, and surgery.
How is brachytherapy done? The way that brachytherapy is given depends on many things, such as where the tumor or tumors are in your body. During brachytherapy, radioactive seeds are placed inside or around the tumor. Seeds are small objects that give off radiation (x-ray energy) in all directions. They can be placed on the skin, in an organ, or in a body cavity. Body cavities are openings in your body, such as your nose, mouth, and vagina. Some seeds can be left in your body permanently, while others will be removed. Brachytherapy may be given in several treatments. You may need to stay in the hospital during this procedure. You may need to return to have treatment every day for about a week.
What are the risks of brachytherapy?
- Radiation kills cancer cells, but it can also harm healthy cells. You may feel very tired during brachytherapy treatment. You may cough up blood or have blood in your saliva. You may be at an increased risk for urinary tract infections. You may have swelling and pain in organs or tissues. Women may have trouble getting pregnant. Your stomach, bowels, or other organs may not work as well as before, or they may stop working.
- Without internal radiation therapy, tumors can grow bigger and damage tissues around them. You can get very weak, lose weight, and have pain. It may be very hard for your body to heal. Cancer cells may spread and grow into new tumors in other parts of your body. These tumors can cause organ failure.
