Sometimes with different stages of the breast cancer if it’s been invasive, they need to cut larger margins out around the lump.I had breast cancer last year.Lumpectomy too.If they need to take any lymph nodes they will from under your arm pit.I had 3 taken.That’s generally because that’s the next port of call the cancer will go to.Be positive.Technology is a wonderful thing today.But knowledge your self up.Ask heaps of questions when you see your surgeon & oncologist.Don’t be scared to ask.
