Cancer prevention: 7 tips to reduce your risk

4. Protect yourself from the sun

Skin cancer is one of the most common kinds of cancer and one of the easiest to prevent. Try these tips:

  • Limit time spent in the sun. This is especially true between the hours of 10 a.m. and 4 p.m. when the sun's rays are strongest.
  • Stay in the shade. When outdoors, be in the shade as much as you can. Sunglasses and a broad-brimmed hat help too.
  • Cover your skin. Wear clothing that covers as much skin as possible. Wear a head cover and sunglasses.
  • Use plenty of sunscreen. Use a broad-spectrum sunscreen with an SPF of at least 30, even on cloudy days. Put on a lot of sunscreen. Put it on again every two hours. Use it more often if you're swimming or sweating.
  • Don't use tanning beds or sunlamps. These can do as much harm as sunlight.
