I had a lumpectomy in 2007 when I was exactly your age. I had radiation but took no medication after. I have not had a recurrence. My lumpectomy was on the underside of my breast and I wore a Comfort Sling from the beginning of the radiation which protected my skin from becoming inflamed. The radiation left me quite tired for a short time, but that seemed to be a small price to pay for the added protection. I wish you continued good health!
