Has anyone had a lumpectomy for breast invasive ductal carcinoma grade 2 er + hr + and her 2 -. Had a 23mm lump removed, but found Dcis on margin. Had a re- exertion for more margin removed. But worried in case margin wont be clear again. What happens next? Waiting is driving me crazy, afraid of a mastectomy, i dont know if dcis is just a bit or scattered in breast. Has anyone gone through this please? Tks
