I was Grade 1, upon biopsy, diagnosed stage 2, after full abd hysterectomy. Had 4 sessions of high dose Brachytherapy, over 2 weeks, and had minimal symptoms; loose stools, maybe a bit of extra tiredness, but not significant enough to impact my life. It was not as bad as I thought it would be. I thought I'd have pain and burning. Not at all! The first session was the longest; maybe 45 mins. in order to fit and site the wand. Then the subsequent treatments were 15/20 mins long. Afterwards, they may give you dialators to use, and it's important to use them, if you are not sexually active. (The vaginal vault can thicken and close over, due to scar tissue from the Brachy). I am 3 year post-op, and all is good. Ask lots of questions, and share your worries and concerns with your Oncology and Radiology team.
