Lumpectomy removed healthy tissue and not the tumour

I have heard of a similar situation with my sister in law - the hookwire dislodged during the surgery as it was near the surface. The surgeon took a large biopsy in the area where it would have been but she still had to go for another procedure later on after more imaging and another hookwire to confirm it was all gone. I am really sorry this happened to you. Medical procedures all have risks as well as benefits.
