Nonmelanoma skin cancer is the most common type of cancer. This type of skin cancer is usually not life threatening, but it should be treated promptly. There are two main types: squamous cell carcinoma and basal cell carcinoma. Symptoms can include a bump that is red or pearly white, or a patch of skin that bleeds, crusts over, or doesn't heal.
