Hi. Try not to worry too much about the brachytherapy. I spent 6 month’s worrying about it while had completed chemo and external beam radiation and it was easy. Maybe a little uncomfortable but it literally lasts minutes. Only side effect was feeling a little tired. The dilator isn’t a big thing and keep in mind the end result of its use: so the area can be clearly visualized. When it’s over you can ring the heck out of the bell!!!
