Squamous Cell Carcinoma
Squamous cell carcinoma is the second most common skin cancer. Risk factors include sun exposure, certain types of viruses, and even old burn wounds. The behavior of squamous cell varies greatly. Sometimes in can be very slow growing and appear like a small patch of irritated skin, other times in can be a large ulcerated wound. This type of skin cancer also has the potential to spread elsewhere in to body (to metastasize), although fortunately that is uncommon. Early treatment and removal can often prevent any spread.
