Squamous cell carcinoma (SCC) is a type of skin cancer that occurs when the squamous cells in the outermost layer of skin begin to grow uncontrollably. SCC is the second most common type of skin cancer, after basal cell carcinoma.
SCC is usually caused by exposure to ultraviolet (UV) radiation from the sun or other sources such as tanning beds. Other risk factors for SCC include fair skin, a history of sunburns, exposure to industrial chemicals such as arsenic, and a weakened immune system.
Symptoms of SCC may include a firm, red bump or patch of skin that may be scaly, crusty, or bleeding. SCC can occur anywhere on the body but is most commonly found on sun-exposed areas such as the face, neck, arms, and hands.
Treatment for SCC typically involves surgical removal of the cancerous tissue. In some cases, radiation therapy or topical chemotherapy may also be used. In general, SCC is highly curable if caught and treated early, but if left untreated or if it spreads to other parts of the body, it can become more difficult to treat and may even be life-threatening.
Prevention of SCC involves avoiding excessive exposure to UV radiation, using sunscreen with a high SPF, wearing protective clothing, and avoiding tanning beds. Regular skin exams with a healthcare provider can also help detect SCC early, when it is most easily treated.
