What to expect

What is Brachytherapy?

Brachytherapy is a dose of radiation given inside or next to the are needing treatment. A high dose is given to the cancer in a short period of time. This reduces the risk of damage to healthy tissue, while treating the tumour.

Before Coming for Brachytherapy 

  • Take your medication as usual.
  • You may have a light meal.
  • Wash the area around your vagina and anus (bum).

Checking in for Your Treatment

Check in for your treatment at the Radiation Reception Desk.

You will be met by a Radiation Therapist who will explain what will happen.

You will change into a hospital gown and be taken into the brachytherapy room, where there is an x-ray machine and other monitors.

Brachytherapy Treatment 

  • You will lie down and your legs will be placed in stirrups, like it would be for a pelvic exam.
  • The Radiation Oncologist may do a pelvic exam before inserting the treatment applicator.
  • Tubes connect the treatment machine to the applicator.
  • The Radiation Therapist will secure the applicator in place.
  • If needed, x-rays will be taken.
  • The radiation source moves through the tubes to give you your treatment.
  • During this time, you will be alone in the room, but we can see you on our monitors, and hear/talk to you through an intercom.
  • When your treatment is finished, the radiation source moves back to the machine and the applicator is taken out.

After Your Brachytherapy

  • You will not be radioactive.
  • You can go home as soon as the procedure is over.
  • Drink 8 – 12 cups of liquid each day, for the next 2-3 days.
  • Some spotting or bleeding from the vagina is normal. We will provide you with a pad.
  • You may have some cramping, which should stop by the end of the day.
  • You will be given a vaginal dilator (with instructions) to begin to use 1 – 2 weeks after your radiation therapy is done.
  • You can have sexual intercourse (sex) when you feel comfortable.

If you get any of these side effects:

  • A fever
  • Severe abdominal (belly) pain
  • A lot of bleeding
  • Cannot urinate (pee)
