I'm 80 in October. I was found to have HER2 positive breast cancer. I had a lumpectomy and started chemo going every week at first, and now every three weeks getting just Herceptin until the middle of Feb. (one year in all). I finished radiation not long ago. I had 30 sessions.
The radiation gave me no trouble at all. My nipple still feels a bit sensitive, but my breast and the skin around it are fine. I had the bottom corner of my right breast removed. It looks kind of funny, but I can see it is starting to fill in a bit. Radiation didn't cause any fatigue.

My biggest problem from it all is the peripheral neuropathy the Taxol caused in my feet.

I'm back to being able to put in a good days work in the yard, and have flown to visit my kids in Portland . Pretty two toned gray hair grew in and I feel really good.
