Skin Cancer: Stay Safe In the Sun

Many people describe sun-tanned skin as a ‘healthy glow’, but nothing could be further from the truth. There is no such thing as a safe, healthy tan.

Sun Damage

Any type of suntan is the result of sun damage caused by exposure to ultraviolet (UV) radiation from the sun. Other types of sun damage include wrinkles, age spots, freckles, tough or leathery skin, dilated blood vessels, sunburn and skin cancer.

The sun emits two types of UV radiation: UVA (which causes ageing) and UVB (which causes burning). Both UVA and UVB rays are undetectable to a person sitting in the sun—you cannot feel them on your skin—and are damaging on cool, cloudy days as well as sunny days. In addition, both types of radiation cause skin cancer.

Skin Cancer

People are most susceptible to skin cancer when they are exposed to sudden, short bursts of sunlight while in places where the sun is very strong, such as locations near the equator or at very high altitudes.

The following characteristics place people at an even higher risk of developing skin cancer:

  • Having a large number of moles on the skin
  • Being a redhead or blonde, and/or having blue eyes, fair skin and freckles
  • Difficulty tanning and skin that is easily burnt
  • A family history of skin cancer
  • Taking medication that increases sun sensitivity

Preventing Sun Damage

The easiest way to prevent skin damage and lessen your chances of getting skin cancer is to avoid getting sunburn. Here are a few tips to help keep you safe in the sun:

  • Stay out of the sun when it is strongest.
  • Wear clothes with tightly woven fabric and a hat that shades your face, neck and ears.
  • Wear sunglasses whenever you are outside to avoid developing cataracts and damaging your retinas.
  • Use sunscreen that has at least 15 SPF every day, especially on your lips and the tips of your ears and nose.
  • Avoid using tanning beds—they are just as damaging as the sun.
  • Protect children from sun damage. Most sun exposure occurs before age 18.

Avoiding excessive sun exposure and sunburn is the best way to protect yourself from sun damage and skin cancer. Routinely inspect your skin for any changes, and if you suspect that a spot on your skin is new, or has changed colour or appearance, consult a dermatologist.
