big mole feels like it is coming away from the skin?

Hello,

Welcome to the ehealthforum and I am really glad to help you out. Your concern is regarding the changes in mole that you are having since a long time. As a thumb rule, any changes in the mole should be evaluated for a melanoma from a dermatologist. Melanoma has an irregular border, is asymmetrical,uneven color and increasing in size. If you notice changes in the mole's/mark’s color, height, size or shape, you should have a dermatologist evaluate it. You also should have it checked if it bleeds, oozes, itches, appear scaly, or become tender or painful.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
