@dintelus6, welcome. You're asking good questions about brachytherapy, some of which have been discussed in these related discussions:

Did your oncologist explain the benefits of treatment vs no brachytherapy and the % risk of recurrence specific for you?

@dintelus6 I was diagnosed with endometroid adenocarcinoma FIGO Grade 1 Stage 1A in 2019. I asked my surgeon about the follow-up appointments and what would be involved. She told me that if I had a recurrence the most likely place would be the vaginal cuff. and so I would have a physical exam (speculum and pelvic exam) every 6 months. That's what happened as my nurse practitioner found a very tiny polyp on the vaginal cuff in 2021. Maybe this is why your doctor recommends brachytherapy?

When I had brachytherapy (2 sessions) after my recurrence the procedure was not at all painful. It was a little uncomfortable only because one must lie very still on a table, legs up in stirrups, while the device is placed in one's vagina. My radiation oncologist was very gentle and the device was easily inserted. The brachytherapy does cause scarring of tissue so after this and also 25 sessions of external pelvic radiation I need to use a vaginal lubricant on a regular basis and a dilator. I still do both of these. These measures keep the vagina in good health for future exams and if one is sexually active. I do not regret having brachytherapy.
