The 2nd Most Common Skin Cancer.

Squamous Cell carcinomas are the second most common type of skin cancer. They usually appear in sun exposed areas and can vary in appearance from a raised lesion with a thick stuck on scale to a growing open, non-healing sore. If left untreated, squamous cell carcinomas run the risk of spreading to other parts of the body. This is more like for lesions appearing on the lips or ears.
