Sun Exposure: The Best Defense Is a Good Offense

Sun Exposure: The Best Defense Is a Good Offense

It’s time to take a closer look at your skin health. Skin cancer is one of the most common cancers in the United States. Melanoma, the most serious type, can grow and spread quickly if it’s not caught early.

Learning what to watch for — and how to protect yourself — can make a difference.

Know Your Risk

Spending a lot of time in the sun is a major risk factor for all types of skin cancer. Ultraviolet (UV) rays can be hard to avoid. They pass through glass (like your car’s windshield) and reflect off pavement, sand, snow, and water.

Protect Your Skin

No matter the season, these steps can help reduce your risk:

  • Wear a brimmed hat. Caps don’t protect as well as hats with brims that go all the way around.
  • Use sunscreen. Choose a broad-spectrum, water-resistant sunscreen with SPF 30 or higher. Apply to all exposed skin and reapply every two hours.
  • Cover up when you can. Long sleeves and pants can help when it’s not too hot. Look for tightly woven fabrics or clothing with an ultraviolet protection factor (UPF).

This advice is for everyone. While skin cancer is more common in people with lighter skin tones and older adults, anyone can develop it.

Check Your Skin

When melanoma is found early, it’s more likely to be cured. Check your skin regularly for new growths or changes in the color, shape, or size of moles, freckles, or birthmarks.

Ask someone you trust to help check hard-to-see areas, like your scalp and back. If you notice anything unusual, have a doctor take a look.

Even if you don’t have concerns, talk with your doctor at your next visit about your risk and whether routine skin exams make sense for you.
