Radiotherapy to the pelvic area usually causes several side effects. These can be diarrhea, irritable bladder (or radiation cystitis), feeling sick, bleeding from the vagina after internal radiotherapy, and soreness and redness of your vulva or back passage.
Commonly, radiation therapy makes your vagina become less stretchy and narrower. To try to prevent or minimize this, it is important to start using vaginal dilators after your treatment. Dilators are cone-shaped objects that come in different sizes. You put the dilator into your vagina gently for 5 to 10 minutes about 3 times a week. This will stretch the vagina and help to stop it from narrowing. Dilators were historically made of plastic or metal and required lubrication and thorough cleaning with soap and water. Many patients found them prohibitively painful and often discontinued critical post-cancer treatment prematurely due to the extreme discomfort. With the arrival of the “Cool Water Cones,” hundreds of women are now able to continue treatment without the pain! Please let us know your experiences with traditional dilators versus Cool Water Cones – we would love to hear the feedback.
