Squamous cell carcinoma (SCC) is the second most common form of skin cancer, characterized by abnormal, accelerated growth of the squamous cells in the skin. These cells develop in the flat, thin cells that line the skin’s surface. The cancer is usually caused by ultraviolet (UV) exposure from excessive sun exposure or the use of tanning beds. Additionally, SCC can develop in scars or chronic skin sores.
While SCC is usually not life-threatening and grows slowly, it can spread to other parts of the body if left untreated. One of the key differences between squamous cell skin cancer and basal cell skin cancer is that SCC is more likely to spread to other organs. If it spreads, it can become life-threatening.
Early diagnosis of SCC is crucial for successful treatment. The five-year survival rate is approximately 99% when SCC is diagnosed early, highlighting the importance of prompt medical attention.
Treatment options for SCC include surgical methods such as surgical excision, Mohs surgery, and radiation in some cases. Mohs surgery, in particular, is considered the gold standard for treating many SCCs, especially those in cosmetically and functionally important areas.
