Endometrial cancer stage 2 grade2

Hi everyone
My sister had her hysterectomy a couple of weeks ago and will soon be undergoing radiation and chemotherapy. I have a couple of questions. First she has a lot of numbness in her pelvic region and down her thigh. She is wondering if she will ever feel anything down there again. Secondly two of her oncologists recommend only vaginal radiation and a third one says she should have pelvic radiation as she had some cancer cells in the pelvic wash. She is worried about getting the pelvic though as she has been told she could get various cancers eg bladder etc down the road in 15 years or so. She is 57 and otherwise in excellent health . Anyone have any thoughts. Thanks so much! You women are amazing.!
