hadfields procedure breast fistula

hi girls i dont think i have bc but i just wondered if anyone knows about the hadfields procedure as i have a chrinic breast abcess with fistula and have been told this is what i have to have i am a bit worried as doc says you only get one chance to get it right if you dont get all the infected area at first go may end up having to loose whole breast. Although this is worst case senario i am a bit worried has anyone undergone this procedure thanks bablicious
