Untreated squamous cell carcinoma 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 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 weakened immune systems, such as someone who takes anti-rejection medications after an organ transplant
