What are the warning signs of skin cancer?

When you’re looking for skin cancer, you’re looking for pre-cancers as well as just cancers. So if you have something that either feels sore, or raw, or feels like a sticker embedded to your skin, or something scaly that comes and goes, you should consider seeing your physician. That could be a pre-cancerous lesion, and that can be treated by simply freezing it or superficially removing it. If you don’t treat it, then there is a possibility that that type of lesion could lead to a skin cancer later.
