Skin Cancer

Skin cancer is the most common cancer diagnosis, and it’s the most preventable cancer. Most skin cancer is caused by damage from the sun’s ultraviolet radiation (UV rays).

This year, an estimated 87,110 people will be diagnosed with melanoma—the most dangerous type of skin cancer—and about 13,590 will die of the disease. In addition, more than two million people are diagnosed with non-melanoma skin cancer annually—either basal cell or squamous cell carcinoma.

Protecting your skin during your first 18 years can reduce your risk of some types of skin cancer by up to 78%.

Recent research on the benefits of vitamin D (made by the skin from sunlight) indicates that just a brief exposure of your face, arms and hands to the sun is sufficient—about 15 minutes a day, three days per week. Talk to your health care professional about Vitamin D and your health.

People with certain risk factors are more likely than others to develop skin cancer. Risk factors vary for different types of skin cancer, but some general risk factors are having—

  • A lighter natural skin color.
  • Family history of skin cancer.
  • A personal history of skin cancer.
  • Exposure to the sun through work and play.
  • A history of sunburns, especially early in life.
  • A history of indoor tanning.
  • Skin that burns, freckles, reddens easily, or becomes painful in the sun.
  • Blue or green eyes.
  • Blond or red hair.
  • Certain types and a large number of moles.

A change in your skin is the most common sign of skin cancer. This could be a new growth, a sore that doesn’t heal, or a change in a mole. Not all skin cancers look the same.

A simple way to remember the signs of melanoma is to remember the A-B-C-D-Es of melanoma—

  • “A” stands for asymmetrical. Does the mole or spot have an irregular shape with two parts that look very different?
  • “B” stands for border. Is the border irregular or jagged?
  • “C” is for color. Is the color uneven?
  • “D” is for diameter. Is the mole or spot larger than the size of a pea?
  • “E” is for evolving. Has the mole or spot changed during the past few weeks or months?

Talk to your doctor if you notice changes in your skin such as a new growth, a sore that doesn’t heal, a change in an old growth, or any of the A-B-C-D-Es of melanoma.

Protection from ultraviolet (UV) radiation is important all year round, not just during the summer or at the beach. UV rays from the sun can reach you on cloudy and hazy days, as well as bright and sunny days. UV rays also reflect off of surfaces like water, cement, sand, and snow. Indoor tanning (using a tanning bed, booth, or sunlamp to get tan) exposes users to UV radiation.

The hours between 10 a.m. and 4 p.m. Daylight Saving Time (9 a.m. to 3 p.m. standard time) are the most hazardous for UV exposure outdoors in the continental United States. UV rays from sunlight are the greatest during the late spring and early summer in North America.

CDC recommends easy options for protection from UV radiation—

  • Stay in the shade, especially during midday hours.
  • Wear clothing that covers your arms and legs.
  • Wear a hat with a wide brim to shade your face, head, ears, and neck.
  • Wear sunglasses that wrap around and block both UVA and UVB rays.
  • Use sunscreen with a sun protection factor (SPF) of 30 or higher, and both UVA and UVB (broad spectrum) protection.
  • Avoid indoor tanning.

For details about these options, see Sun Safety.

The U.S. Preventive Services Task Force (USPSTF) has concluded there is not enough evidence to recommend for or against routine screening (total body examination by a doctor) to find skin cancers early. This recommendation is for people who do not have a history of skin cancer and who do not have any suspicious moles or other spots. Report any unusual moles or changes in your skin to your doctor. Also talk to your doctor if you are at increased risk of skin cancer.

For more information, see the USPSTF’s Screening for Skin Cancer: Consumer Guide [PDF-90KB] and visit the National Cancer Institute’s Skin Cancer Screening.
