It is ideal that you consult a dermatologist asap. Pay heed to your wife's tantrums! She is right! Make sure that you go to the right dermatologist, who is trustworthy enough. Do not fall for those fake doctors who do not even have received proper cosmetic clinical skin care training!
See a dermatologist. I had a friend who died of skin cancer. She just couldn't be bothered to go to the doctor for a seemingly insignificant lesion on her arm that wouldn't go away.
