Intravaginal Brachytherapy

This information will help you get ready for intravaginal brachytherapy. It will help you know what to expect before, during, and after your treatment. It will also help you learn about side effects and how to care for yourself during treatment.

Read through this resource at least once before you start intravaginal brachytherapy. Use it as a reference in the days leading up to your treatments so you can prepare as much as possible. Bring this resource to all future appointments with your radiation oncologist. You and your healthcare team will refer to it throughout your treatment.

About Intravaginal Brachytherapy

Brachytherapy is a type of radiation therapy. Radiation therapy kills cancer cells by making it hard for them to multiply.

With brachytherapy, a radioactive source is temporarily placed inside your body, inside or near the tumor(s). This means that the tumor gets a large amount of radiation, while nearby healthy tissue gets less radiation and is less likely to be damaged. With intravaginal brachytherapy, the radioactive source is placed in a cylinder that’s placed in your vagina.

Most people get a total of 3 treatments that last about 5 to 15 minutes each. Your radiation oncologist may change the timing or number of the treatments. They will talk with you about what to expect.

Before Your Treatment

You don’t need to do any special preparation before your treatment. You can eat and drink as usual.

When you arrive for your treatment appointments, a staff member will ask you to take off any clothing below your waist and change into a hospital gown. They will also ask you to empty your bladder. Then, they will bring you into a treatment room.

During Your Treatment

Once you’re in the treatment room, your doctor will do a pelvic exam. They will place the cylinder into your vagina. The cylinder is the same shape as a tampon, but bigger. You may feel some pressure while it’s in place. Your doctor will attach a cable to the cylinder. The cable is connected to a machine that stores the radiation source. Then, an x-ray scan will be taken to make sure the cylinder is in the right place.

Once everything is set up, the staff will leave the room and close the door. A computer will send the radioactive sources through the cable and into the cylinder. You will be alone in the room during your treatment, but the staff will able to see you on a monitor and hear you through an intercom at all times.

It’s important to lie still during your treatment so the cylinder doesn’t move. Because the radioactive sources are placed inside the cylinder, you won’t feel them. However, if you’re uncomfortable or need help, tell your radiation therapists. They can turn off the machine and come in to see you at any time, if needed.

After your treatment is done, the radioactive sources will move back into to the machine. Your doctor will then remove the cylinder.

You don’t need to follow any special precautions after your treatments. You can leave the hospital right away. Neither you nor your clothes will become radioactive during or after treatment. It’s safe for you to be around other people.
