Causes

Cancer occurs when cells in the body divide without control or order. Eventually these uncontrolled cells form a growth or tumor. The growths invade and take over nearby tissue. It is not clear exactly what causes these problems in the cells but it is probably a combination of genetics and the environment.

Risk Factors

Areas of skin that are damaged have a 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:
  • History of radiation or ultraviolet light treatment
  • Childhood sunburns , freckling, or long periods of sun exposure
  • A personal history of skin cancer
  • A family history of skin cancer
  • Blonde or red hair
  • Blue or green eyes
  • Fair skin that rarely tans
  • Treatment that suppresses the immune system, such as such as having an organ transplant
  • 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)

Symptoms

  • A raised red patch that is scaly or rough
  • A raised patch of skin that may appear to have horn-like rough edges
