Hi, I had masectomy, chemo and radiation in 2019/2020. 2023 I had Diep reconstruction. Pleased with results and have been carrying on which my life. I decided not to have phase 2 as being in my 70’s one op is enough. The scar across my Diep has always stayed red, thought to be that the radiation may have caused the skin to be thin. Just recently it feels like my Diep has got bigger the muscle in my chest is firm. But worryingly is a red patch and a small raised bit has appeared on the scar Do I go back to the hospital who did the surgery or the cancer ward at the  hospital or is my GP the first port of call? Thank you for any replies Silver
