Causes, Risk Factors, and Prevention TOPICS

Can basal and squamous cell skin cancers be prevented?

Not all basal and squamous cell skin cancers can be prevented, but there are things you can do that could help reduce your risk of getting these and other skin cancers.

Limit your exposure to ultraviolet (UV) rays

The most important way to lower your risk of basal and squamous cell skin cancers is to limit your exposure to UV rays. Practice sun safety when you are outdoors.

Look for shade

Simply staying in the shade is one of the best ways to limit your UV exposure.

“Slip! Slop! Slap! ®… and Wrap”

This catchphrase can help you remember some of the key steps you can take to protect yourself from UV rays. If you are going to be in the sun:

  • Slip on a shirt.
  • Slop on sunscreen.
  • Slap on a hat.
  • Wrap on sunglasses to protect the eyes and sensitive skin around them.

Avoid tanning beds and sun lamps

Many people believe the UV rays of tanning beds are harmless. This is not true. Tanning lamps give out UV rays, which can cause long-term skin damage and can contribute to skin cancer. Most skin doctors and health organizations recommend not using tanning beds and sun lamps.

Protect children from the sun

Children need special attention, since they tend to spend more time outdoors and can burn more easily. Parents and other caregivers should protect children from excess sun exposure by using the steps above. Children need to be taught about the dangers of too much sun exposure as they become more independent.

Avoid harmful chemicals

Exposure to certain chemicals, such as arsenic, can increase a person’s risk of skin cancer. People can be exposed to arsenic from well water in some areas, pesticides and herbicides, some medicines and imported traditional herbal remedies, and in certain occupations (such as mining and smelting).

Check your skin regularly

Checking your skin regularly may help you spot any new growths or abnormal areas and show them to your doctor before they even have a chance to turn into skin cancer. For more information, see the section “Can basal and squamous cell skin cancers be found early?
