@gratefulcat As @val64 wrote you should make the decision that is the right one for you. I don’t know of anyone in our Support Group that refused radiation treatment for a low-to mid-risk endometrial cancer. I checked back through our Support Group and did not find anyone however I encourage you to do the same. You may find a discussion that is helpful to you.

I had external pelvic radiation (25 treatments) and 2 vaginal brachytherapy for a recurrence of endometrial cancer (endometrioid adenocarcinoma, FIGO 1, Stage 1a). The cancer was considered low grade and non agressive. I write this because not all cancers are alike. So the recommendations that are made and the decisions a person makes depends on the kind of cancer and how agressive it is.

During external pelvic radiation I had a few instances of diarrhea but that cleared up within a few weeks after I completed the treatments. I was informed that I also might have bladder problems that would feel like a UTI during external pelvic radiation and that occurred briefly. Mostly I was fatigued. It was recommended that I use a vaginal moisturizer and a dilator after brachytherapy which I’ve continued to do.

I am 16 months “out” from the radiation treatments and have had no lasting effects from radiation.

Here is a discussion that you may find relevant to your question.

How did you feel after pelvic radiation was completed?
