Re: old scar suddenly itchy and irritated... possible skin cancer?
Hi, there are many types of skin cancer. Not all are malignant. I have had four mole types removed from my nose called (Keratoses Carcinoma). A biopsy revealed they were not malignant. I would suggest any suspicious type mole or skin discoloration be investigated by your Dr. Mine kept itching and one grew rapidly which had to be cut out , the others were treated with Liquid Nitrogen. It could just be his watch rubbing on the old wound. Better be safe than sorry, get his Dr to decide. Solofelix.
