Squamous cell carcinoma (SCC) is the second most common type of skin cancer, and is derived from the cells that make up the top layer of skin.

They are most common in people with pale skin, and on sun-exposed sites such as the head, neck, arms, hands and legs. They are most often, but not exclusively, found in association with actinic keratosis (sun spots).

Squamous cell carcinomas tend to present as an erythematous painful lump that may become crusted or even ulcerated. They are most dangerous when occurring on the lips, ears and nose, and should always be treated seriously due to their ability to spread.

Surgery is the most common treatment used in the management of squamous cell carcinoma.
