Risk Factors

Areas of skin that are damaged have higher risk of cancer. Skin that is regularly exposed to the sun is most likely to develop skin cancer. Squamous cell carcinoma may also develop in skin that has scars, burns, or exposure to chemicals or radiation.
Factors that increase your risk of developing squamous cell carcinoma include:
  • Increasing age
  • Blonde or red hair
  • Blue or green eyes
  • Childhood sunburns, freckling, or long periods of sun exposure
  • Fair skin that rarely tans
  • A family history of skin cancer
  • A personal history of skin cancer
  • Treatment that suppresses the immune system, such as such as having an organ transplant
  • History of radiation or ultraviolet light treatment
  • Frequent use of tanning beds
  • Exposure to cancer causing chemical such as arsenic, tar, or some insecticides
  • Being a smoker
  • Past infection with human papillomavirus (HPV)
