When we hear the word cancer, skin cancer is usually not the first thing to come to mind but its actually the most common type of cancer in humans. The three main types of skin cancer are each named after the type of cell that becomes cancerous basal cell carcinoma, squamous cell carcinoma, and melanoma. Heres what to know about the three main types of skin cancer and what to look for when checking your skin:

Basal cell carcinoma (BCC)

What to know: Basal cell carcinoma is the most common type of cancer (up to 3/4 of all skin cancers), originating from cells in the basal layer of the skin. BCCs are typically found on areas with the greatest sun exposure - head, neck and arms but can be found in unexposed areas as well. Basal cell carcinomas typically do not metastasize (spread to distant locations in the body), but they can grow into the surrounding tissue causing damage. BCC can be treated and cured with surgery.

What to look for: Basal cell carcinomas will typically look like a flesh-colored or pearly bump or patch of skin. Sometimes, the bump will have tiny blood vessels called telangiectasias. The cancer can also appear flat or crusted. BCCs can bleed easily and may show up as a pimple that doesnt heal or a spot that bleeds after shaving.
