Because my DCIS area was very small (6mm x 4mm) and no residual DCIS was found during lumpectomy, my risk of recurrence is very low overall. So, 5 radiation treatments were recommended if I wanted to go that route. Aromatase inhibitor also recommended if I wanted to go that route. Lowers my risks even further, but I am still very much in the +/- camp on whether I will continue it. I generally just haven't felt well on it. Tired, fatigue, poor sleep, emotional. Not sure it is worth it....
