No Man Boobs But a Very Strange Tan

With the radiation treatments done to prevent gynecomastia, I now have a "tan" (radiation burn?) in rectangle over the center of each pec.  It will be sensitive to sunlight for at least a year, the skin will peel and the hair will fall out in that specific, red area, never to return. Radiation.......very strange stuff.  Glad this is all I'll ever do.
