What to Look For
Squamous cell carcinomas typically appear as persistent, thick, rough, scaly patches that may bleed. They often look like warts and sometimes have open sores with a raised border and crusted surface over an elevated pebbly base. The skin around them typically shows signs of sun damage such as wrinkling, pigment changes and loss of elasticity.
In addition to the signs of SCC shown here, any change in a preexisting skin growth, such as an open sore that fails to heal, or the development of a new growth, should prompt an immediate visit to a physician.
