What Is Skin Cancer?

Skin cancer is an abnormal, uncontrolled growth of skin cells, usually from harmful ultraviolet rays. This common form of cancer ordinarily occurs on areas of the skin exposed to sunlight but can form anywhere.

For skin cancer to occur an “error” or mutation occurs in the DNA of the skin cells. When these mutations occur the cells can rapidly grow and form a mass of cancer cells that can spread through multiple layers of the skin.

What Are The Causes Of Skin Cancer?

The causes of skin cancer vary and include:

  • Exposure to UV rays ( from sunlight, tanning beds)
  • Smoking in those with SCCs ( squamous cell carcinomas)
  • Certain strains of HPV infection- can lead to skin cancer of the genitals, oral mucosa and lips
  • A patient with Immune suppression-such as HIV disease and organ transplant recipients.
  • Certain chronic skin conditions-such as lichen sclerosus
  • Genetic conditions
  • Exposure to arsenic

Squamous cell carcinomas (SCCs) – most often occuring on skin that is sun exposed this type will present as hard red nodules or flat scaly lesions especially in people with darker skin complexions

Melanoma – this type can develop in all areas of the body, even those not exposed to the sun. It can present as brown spotting, in moles that change size and color, oddly shaped and colored lesions and in lesions that cause itching or burning sensations.
