Cut a mole a year ago, it bled, it's dark red or light red at times with dark color under skin, it's very small and round

Have it checked!: Any mole that is chronically irritated (shaving), changing in size, shape, or color, has a dark coloration, asymmetry, or irregular border, or is larger than a pencil eraser should be checked by a plastic surgeon or dermatologist. Shave biopsy is not recommended; remove it completely--if it's bad, you've not cut into it or destroyed valuable information (thickness); if it's not, it's gone!
