Mk, my sister just finished her 10th week of radiation for breast cancer. She was very tired, wasn't bad at first, then progressively more. The skin of her breast, reddened, and dried out some, was some small swelling, (which also may have been what was still left from the surgery to have the lump removed) She was also still sore to the touch in the breast area, again may have all been from the surgery, and didn't really get a chance to heal before the radiation started. She also will be taking a med for the next 5 years. At this point she is cancer free, not sure how this pill is to help her, but shes gonna take it. Now if they can fix her emphysema and her copd life would be good. 
Keeping you and your hubby in my prayers, as I believe they help, stay strong and love your man with ever fiber of your being!
