My breast surgeon has quoted the following percentages in achieving positive margins afger first lumpectomy surgery:

Positive margin rates vary- my own experience is ~15%. A huge study in England recently showed an 18% rate. In the U.S> overall, probably between 15-30%.

I was astonished to hear it was so low after she relayed this to me after she told me I may have to undergo a second lumpectomy if positive margins were not achieved. During my first visit with her she recommended lumpectomy followed buy corrective surgery on the same day. After meeting w/the plastic surgeon he indicated corrective surgery would take place after lumpectomy. When I asked her about the discrepancy in surgical events she said corrective surgery could not take place if clear margins were not achieved - which I can understand, however I don't understand why it was communicated to me when we first met both surgeries would talke place same day. Now being somewhat doubtful of her expertise.......

As always appreciate input received from this board of brave-brave members.

I have a whole thread going on this topic that's near the top. Different surgeons have different definitions of what is a clean margin. I too was surprised to see how large a percentage of women had additional surgery after lumpectomy because of margin issues. The frightening thing was how many of these women found additional cancer after the first lumpectomy. Not to scare you, but I'd definitely research margins before determining that they are clear. I will say with mine that they found additional cancer on the re-excision.

Good luck figuring this out. Remember to ask lots of questions!
