Squamous cell carcinoma is a common form of skin cancer that affects over 250,000 people in the United States each year. It is usually caused by excessive, long-term exposure to ultraviolet rays from the sun and most frequently affects people over the age of 50 and with pale skin. Squamous cell carcinoma does not cause pain or any other symptoms, but develops as a growth on the skin, usually in sun-exposed areas. These growths can vary in appearance and may be new or a change to a pre-existing scar.

Squamous cell carcinoma affects the area just below the outer surface of the skin. Most cases can be completely removed through minimally invasive procedures that may include freezing, excision, laser therapy, Mohs surgery or radiation therapy. Skin cancer can usually be treated successfully if detected and removed quickly. It is important to take precautionary measures such as avoiding sun exposure and performing regular skin checks to prevent new cases of squamous cell carcinoma.
