Skin cancer

Skin cancer happens when cells in your skin grow abnormally and out of control. The cancer cells can spread to other parts of your body.

Skin cancer may first appear as a new mole, a change in a growth or mole, a sore that doesn't heal, or an irritation of the skin.

Exposure to the sun is the most common cause of skin cancer.

There are three major types of skin cancer:

  • Basal cell skin cancer is the most common form. It grows slowly and seldom spreads to other parts of the body.
  • Squamous cell skin cancer also rarely spreads, especially if it is found and treated early. But it's more likely to spread than basal cell cancer.
  • Melanoma grows and spreads rapidly and can invade other organs, such as the liver, lungs, or brain.

How can you care for yourself to prevent skin cancer?

  • Wear a wide-brimmed hat and long sleeves and pants if you are going to be outdoors for a long time.
  • Avoid the sun between 10 a.m. and 4 p.m., which is the peak time for UV rays.
  • Wear sunscreen on exposed skin. Make sure to use a broad-spectrum sunscreen that has a sun protection factor (SPF) of 30 or higher. Use it every day, even when it is cloudy.
  • Do not use tanning booths or sunlamps.
  • Use lip balm or cream that has sun protection factor (SPF) to protect your lips from getting sunburned.
  • Wear sunglasses that block UV rays.
