Untreated squamous cell carcinoma of the skin can destroy nearby healthy tissue, spread to the lymph nodes or other organs, and may be fatal, although this is uncommon.

The risk of aggressive squamous cell carcinoma of the skin may be increased in cases where the cancer:

  • Is particularly large or deep
  • Involves the mucous membranes, such as the lips
  • Occurs in a person with a weakened immune system, such as someone who takes anti-rejection medications after an organ transplant
