Hello! My best advice is what you are already doing, seeing a doctor. I would be prepared to answer questions relating to how long this has been there. Your dermatologist may want to know if this is something that has changed in appearance, size, or color. I had skin cancer myself and I did as much research prior to the appointment as possible. I would read up on anything that you think might be relevant to what you are seeing on your skin. This might not be a big help, but I wanted to encourage you that you are seeing a professional.
