I had a mole shave biopsied and the result stated severely abnormal - recommend removing slightly more. Dermatologist said I needed to set up a punch biopsy. I went in and had this done and I think he removed it with 3mm margins. Im extremely concerned because after researching I have learned that severely atypical moles should be treated like melanoma in situ and be excised with 5 mm margins. Im concerned that it was not an excision and just a punch biospy as well. Should I be worried?
Also, others were removed through a shave biopsy - two were moderately atypical and one was mildly atypical. The dermatologist said that no further treatment was needed on any of these unless the area repigments. Is it possible that a shave biopsy can give clear margins on moderate atypical moles?
