I had a lumpectomy along with removal of 13 lymph nodes (cancer present in 7) on 1/3/2020. I had been on the hormone blocker Letrozole for 7 months prior and remained on it until starting chemo (because of the lymph node involvement.) My surgeon did not get clear margins, and so I had a 2nd lumpectomy on 1/31/2020. I began chemo a month later followed a month after that by radiation. I then resumed the Letrozole the day after finishing radiation. I suffered major fatigue during chemo, so perhaps I didn't notice; but I don't remember any significant fatigue from radiation. I actually walked to radiation on average of 4x a week to rebuild strength and balance
