@Mrs_Katie_06 hope you are healing well and get stronger post surgery. I also had ILC in two places a 7cm mass and a smaller 1cm in a different spot, also had a positive lymph node. I progressed from heading for a lumpectomy to a mastectomy followed by an axilla clearance and was really happy with my choice given the final pathology results. I am currently on the tail end of a five month chemo journey. I think it’s great that you are questioning and an active in championing what is right for you. My view is that the surgery removed the known or visible cancer and chemo and radiation is mopping up anything that is hanging around not visible - even on PET scans. My oncologist described chemo as a systemic treatment, while the radiologist described radiation as localised treatment and together they work to minimise recurrence. Sounds like both treating teams are on the same page - write your list of questions and pepper them and also your breast care nurse with your questions until you are satisfied. Thinking of you and good luck with your decision - keep us posted on how you go.🪷
