To me, the wording "abnormal" sounds more like atypical. I've never heard the word abnormal biopsy (and I've been around this site over 15 years). If it was melanoma, she would have said cancer or melanoma – at least in my book. Atypical or dysplastic moles ARE abnormal. They are not considered benign but they are not considered cancer either. They fall in between. Think of it on a scale. 0 is benign. 10 is in situ melanoma. What if the mole had some features that were not totally normal, but most were. That might rate about 3 on our scale. Other lesions might have more atypical features – but still not enough to be considered cancerous. Maybe a 7. They don't score melanoma this way, but they do look at a variety of factors to determine whether or not a lesion is cancerous. And there are lesions that fall in between. Many times these lesions are labeled mild, moderate or severely atypical (dysplastic). The more atypical the lesion, the more concerning. Severely atypical lesions are usually removed with an extra 5mm margins, just as a precaution. Moderately atypical lesions may have conservative margins. So there are definitely reasons she could be calling you back in, but that doesn't mean it has to be melanoma. Additional surgery might be needed to get better margins for even a non-cancerous lesion. Again, don't presume. I would, however, get a copy of your pathology report so you know exactly what was found.
