Skin Cancer Prevention

Non-melanoma skin cancer is the most common type of cancer in the United States, according to the National Cancer Institute. And while melanoma skin cancer accounts for just 4 percent of all skin cancers, it causes 75 percent of all skin cancer deaths. Many of these skin cancers can be prevented simply by avoiding exposure to excessive ultraviolet radiation.

Cancer

Ultraviolet (UV) radiation causes skin cancer by changing skin cell DNA, causing successive generations of skin cells multiply and grow in an uncontrolled fashion.

Sun

The sun is the most significant source of UV radiation, so skin cancer prevention is centered around protection from the sun.

Age

Though skin cancers most often appear after age 50, the sun damage that causes skin cancer begins in childhood. To most effectively prevent skin cancer, daily protection from the sun should begin in childhood as well.

Tanning

UV radiation from from tanning beds or tanning bulbs also increases skin cancer risk, according the the National Cancer Institute. To prevent skin cancer, all types of suntanning should be avoided.

Prevention/Solution

SPF ratings on sunscreen indicate protection from UVB radiation only, but protection from UVA rays is just as important for preventing skin cancer. Look for a sunscreen that offers "broad spectrum UVA protection," as well as SPF 30 or higher.
