I was diagnosed with DCIS in September, had surgery in November and had radiation in the prone position for 5 days from 1/6/25 through 1/10/25. It was no big deal. The procedure took about 15-20 minutes and most of that time was spent getting into the proper position. There was zero pain and after 5 days the only issue was very, very mild tenderness of the breast. I wouldn't even describe it as pain. I used Aquaphor on the breast and had no redness, no discoloration of the skin, no dryness of the skin....NOTHING. The staff at the Charlton Building at Mayo (Rochester) was very kind and professional. Good luck and I hope your experience is as good as mine was.
