i wish that i could answer your question but to blindly comment on a prior surgery would be impossible since i do not know the medical details of your case. only your surgeon can address this issue. please keep in mind that cancer does not always "stand out" and be obvious during surgery so it is possible that a tiny piece was missed. i really can't say but at least the follow-up mammogram spotted "something". this "something" may not necessarily mean a "piece of cancer" since there can be many artifacts that mimic a suspicious reading. it is up to you to trust your doctor but medicine is far from 100% perfect 100% of the time. i am sure you will receive an explanation from your doctor. i wish you the very best.
went for 6 mth mammo after surgery. still need needle biopsy in same place. why wasnt this removed during surgery? . radiologist said there is still a piece at the biopsy site. i dont understand why this wasnt removed during surgery. is it necessary to do this biopsy? i have an appt with my surgeon but not sure how much i trust her now. the biopsy came back negative 6 mths ago.
