Thank you for your question. Abnormal cells found with biopsies of moles indicate exactly that, abnormal cells. When they are severely abnormal or atypical, then it is recommended to remove the mole completely because if the mole is left alone, there is a risk of the mole becoming malignant, aka cancerous. I highly recommend you consult with your physician who is going to perform the surgery regarding your questions and concerns. Take care and good luck.
