Moles, all moles, are the proper object of a medical exam. The doctor may see things you can't see and your wife can evaluate properly. Take it from a guy who has skin cancers removed almost yearly, every mole deserves medical evaluation to determine if it is cancerous or precancerous. The vast majority aren't a problem and the overwhelming majority of those that are problematical have a 99.9% cure rate if caught early. The treatment is really nothing to be worried about. However, that being said, last year we buried a friend who had ignored a basal cell cancer on his forearm for years, absolutely curable until you let it go--by the time he went to get it treated it had spread to his lymph system and elsewhere. There's just no reason. Even the very dangerous melanoma is very curable, if caught early. Get to a doctor, use the citrus juice for summer beverages!
