What is Squamous Cell Carcinoma?

The main symptom of squamous cell skin cancer is a growing bump that may have a rough, scaly surface and flat reddish patches.

The bump is usually located on the face, ears, neck, hands, or arms, but may occur on other areas.

A sore that does not heal can be a sign of squamous cell cancer. Any change in an existing wart, mole, or other skin lesion could be a sign of skin cancer.
