Warning Signs and Images

What to Look For

Squamous cell carcinomas typically appear as persistent, thick, rough, scaly patches that can bleed if bumped, scratched or scraped. They often look like warts and sometimes appear as open sores with a raised border and a crusted surface.

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.

  • An elevated growth with a central depression that occasionally bleeds. A growth of this type may rapidly increase in size.

  • A wart-like growth that crusts and occasionally bleeds.
