What Is Sebaceous Carcinoma (SC)?

Sebaceous carcinoma is a rare skin cancer that forms in the sebaceous glands that lubricate the skin. While it can develop anywhere on the body, it is most commonly found on an eyelid. It can spread (metastasize) elsewhere in the body if untreated.

Most people diagnosed with sebaceous carcinoma are between 60 and 80, though the disease can affect all ages. There are several suspected risk factors:

• Unprotected sun exposure
• Weakened immune system from medical conditions like human immunodeficiency virus (HIV) or cancer
• Previous radiation therapy to the head or neck
