Hi @colleenyoung. Yes he mentioned necrosis, mentioned could be something was left behind from surgery, and that it was suspicious enough to warrant the biopsy. They will do the needle first to see if they can draw fluid from it and if not then the biopsy. He said I would not have found it myself it was the ultra sound that picked it up. He said it was about 6 cm. My original cancer was 2 cm Invasive ductile cancer and very close to the chest wall and grade 3 with no lymph node involvement. My onco score was 51. I am still trying to keep a positive attitude here. Can’t do anything about it until it slaps you in the face🙂. I will keep you posted. Not sure how long it will take to get the results? I am in Canada 🇨🇦
