Skin Cancer: Risks and Prevention

​

​

   Most skin cancers are linked to exposure to

UV rays. Ultraviolet radiation causes damage to

DNA in skin cells which can allow cancer to

develop. But other factors contribute to skin

cancer since some skin cancers are found on

body parts that are never exposed to the run.

​

Risk factors for skin cancer:

• Fair skin—Although anyone can have skin cancer, people with fair skin, or blond or red hair, and light-colored eyes are more likely to develop skin cancer. (Remember, even those with darker skin types can develop skin cancer.)

 

• Excessive sun exposure—Excessive exposure to ultraviolet rays of any kind can cause skin cancer. It is not only the sun’s UV rays that cause cancer. Indoor tanning methods, such as tanning beds and sun lamps, use UV rays and can cause cancer.

 

   People who live in sunnier climates or at higher altitudes are more at risk for excessive sun exposure and should take extra precautions to avoid getting too much sun.

 

• Moles—People who have many moles are more susceptible to developing skin cancer and should check their moles regularly for changes that might indicate a growing lesion. They are usually larger and more irregular than normal moles.

 

• Family History—If there is a family history of skin cancer, you are more at risk of developing skin cancer. Monitor any moles or lesions you may have more carefully and avoid excessive exposure to the sun. Always wear sun block if you are going to be in the sun for a longer than usual time.

  

• Exposure to radiation—Radiation therapies for skin conditions such as eczema result in a higher risk for skin cancer.

 

• Exposure to toxic substances—Some toxins, such as benzene, heavy metals, and ozone, may increase the risk of skin cancer.

 

How to Prevent Skin Cancer

● Limit sun exposure especially during the times of day when UV rays are most intense (usually between 10:00 am and 4 pm).

​

● Use sunblock when you are going to be in the

sun. Use a sun protective factor (SPF) of 15 or

higher with both UVA and UVB protection.

Reapply every 2 hours or more often if

swimming or if sweating profusely.

​

● Wear sunglasses to protect your eyes against

UV rays.

​

● Wear protective clothing and a hat to prevent

sun exposure.

​

● Do not use indoor tanning methods such as tanning beds or sun lamps. They are NOT safer than sun tanning.
