You’ll get radiation every day at a hospital or clinic. You'll likely get treatment 5 days a week for a few weeks or months. The length of time depends on the type and dose of radiation.
Each treatment lasts only a few minutes. It’s a lot like getting an X-ray. The machine doesn't touch you during treatment, and treatment doesn't hurt. You may see lights from the machine that are lined up with the marks on your skin. This helps the therapist know you’re in the right position. The therapist will leave the room while the machine sends radiation to your tumor. During this time, he or she can see you, hear you, and talk to you. When the machine sends radiation to your tumor, you'll need to be very still. But you don’t have to hold your breath.
Your radiation oncologist or nurse can tell you what to expect during and after treatment. Ask any questions so you know what to expect.
