I had 16 radiation treatments and 4 boosters. I'm at 4 weeks after treatment and still have fatigue. It's not horrible and I'm dealing with it. My oncologist said it can sometimes take months to go away. I also had total knee replacement surgery a couple of months before the DCIS diagnosis, biopsy and 3 lumpectomies so my body has a lot of healing to do. I think my biggest issue is that I feel guilty for not doing the things I normally would be doing this time of year but I just can't muster up the energy to do them. Such as planting flowers and a garden. I look at all of it as just overwhelming - so I've decided to not do them this year. I'm 72 so that might be a part of it as well. It's frustrating but I'm glad to be alive and that this was caught early.
