I am a radiation oncology doctor
if your uterine cancer spread to your cervix, this would be stage II uterine cancer
vaginal cuff brachytherapy is actually the least toxic of the radiation treatments, and gives a smaller area radiation compared to the whole pelvis radiation for 25 treatments which treats your uterine tumor bed, pelvic lymph nodes as well as your upper vaginal cuff.
the number 1 place for uterine cancer recurrence is the vaginal cuff, where your uterus was removed and the upper vagina is sown together.
the vaginal brachytherapy is radiation only to 0.5cm depth to the vaginal wall in the upper 2/3 of the vaginal canal.
yes, woman do have risks for vaginal adhesions after this procedure
but this can be prevented with regular vaginal intercourse every week for 4-6 months
or use of a vaginal dilator for 5 minutes a day, 4-5 days a week for 4-6 months.
scar tissue from radiation forms in the first 4-6 months and can be prevented with these prevention methods
to allow for future intercourse and future vaginal gyn examinations to be easier to do.
I would hate for your uterine cancer to come back on your vaginal cuff, cause bleeding and require you to do more surgery and more radiation at that point and lower your chance of cure if your uterine cancer came back.
most radiation doctors would have recommended just the vaginal cuff brachytherapy over the 25 whole pelvic radiation as being more important if they had to pick one radiation treatment for you.
