Squamous Cell Carcinoma

Squamous cell carcinoma (SCC) is an uncontrolled growth of abnormal cells arising in the squamous cells, which compose most of the skin’s upper layers (the epidermis). SCCs often look like scaly red patches, open sores, elevated growths with a central depression, or warts; they may crust or bleed. SCC is mainly caused by cumulative UV exposure over the course of a lifetime. It can become disfiguring and sometimes deadly if allowed to grow. An estimated 700,000 cases of SCC are diagnosed each year in the US, resulting in approximately 2,500 deaths.

SCCs may occur on all areas of the body including the mucous membranes and genitals, but are most common in areas frequently exposed to the sun, such as the rim of the ear, lower lip, face, bald scalp, neck, hands, arms and legs. Often the skin in these areas reveals telltale signs of sun damage, such as wrinkling, changes in pigmentation, and loss of elasticity.

Definition of squamous cell carcinoma

Squamous cell carcinoma is a common form of skin cancer that develops in the thin, flat squamous cells that make up the outer layer of the skin.

Squamous cell carcinoma is usually not life-threatening, though it can be aggressive in some cases. Untreated, squamous cell carcinoma can grow large or spread to other parts of your body, causing serious complications.

Most squamous cell carcinomas result from prolonged exposure to ultraviolet (UV) radiation, either from sunlight or from tanning beds or lamps. Avoiding UV light helps reduce your risk of squamous cell carcinoma and other forms of skin cancer.
