@klue It's great that your oncologist provided this helpful information to you. I've had brachytherapy. It was awkward because I had to lie very still on a table with my legs up in stirrups during the treatment. The medical staff were very compassionate and did so much to help me very comfortable. I had no reactions or after effects from the brachytherapy. I did and still do use a moisturizer and vaginal dilator because brachytherapy to the vagina results in scar tissue. Your oncologist and/or the oncology nurse will likely talk with you about this. Do you know when your brachytherapy is scheduled?
