Squamous Cell Carcinoma
Squamous cell carcinoma (SCC) is the second most common skin cancer in the United States after basal cell carcinoma. Over a million cases are diagnosed every year. Squamous cell carcinomas are most commonly seen on areas of chronic sun exposure such as the head, neck, arms and lower legs. Squamous cell carcinomas typically present as red, rough scaly spots that will not heal. The spots may be slightly swollen, tender and have crust/scabs on the surface. Squamous cell carcinomas can spread to other organs, but if detected early can be effectively treated. If you have a new or changing spot, don’t delay and call for a skin exam by one of Front Range Dermatology Associates highly skilled providers.
