Radiation therapy is a method used to kill cancer. The goal is to get as close to the cancer without harming structures around it. In some cases, it’s used with chemotherapy (called chemoradiation).
- After surgery to kill any cancer cells left behind
- To ease problems from cancer that has spread and help you live longer
Radiation is made by a machine outside the body. The type of machine will depend on where the cancer is, how large it is, and the type.
Side Effects and Management
Since this type is aimed at the pelvis, you may have:
- Erectile dysfunction
- Blood in the stool
- Pain during bowel movements
- A harder time holding urine
- To pass urine more often
- Problems with fertility—If you think you may want children, talk to your doctor. Do so before you’re treated. You may be able to have your semen frozen for later use.
There are many ways to treat these problems. Other common issues are dry, sore skin, nausea, vomiting, and feeling tired because of anemia. Talk to your healthcare team as soon as these appear.
