Hello Ammie... Welcome to the forum. So sorry your husband and you have been through this difficult time. I don't have any experience with radiation, so I will have to rely on the input of others for that. I do know several members have had chemotherapy after their RC, but not sure about radiation treatments.
Do you have a copy of your husband's pathology report? A bit more information may help us give you better answers. When his doctor talked about clean margins, do you know where they took the margins, or how many lymph nodes were tested? Where is the doctor suggesting applying the radiation?
You are certainly doing the right thing by searching for information. When is his doctor wanting to start these treatments?
Best wishes... Catherine
