The majority of skin cancers can be avoided. Follow these skin cancer prevention tips to stay safe:
In the middle of the day, stay out of the sun. The sun’s rays are greatest for many people in North America between 10 a.m. and 4 p.m. Even in the winter or when the sky is hazy, schedule outside activities for other times of the day.
UV radiation is absorbed all year, and clouds provide little protection from harmful rays. Sunburns and suntans cause skin damage and raise your chance of developing skin cancer, therefore avoiding the sun at its brightest helps you avoid them. Skin cancer can also be caused by long-term exposure to the sun.
Wear sunblock all year. Sunscreens do not block all dangerous UV light, particularly the UV that can cause melanoma. They do, however, play an important part in a comprehensive sun protection program.
Even on cloudy days, use a broad-spectrum sunscreen with an SPF of at least 30. Apply sunscreen liberally and reapply every two hours — or more frequently if you’re swimming or sweating heavily. Apply sunscreen liberally to all exposed skin, including your lips, the tips of your ears, the backs of your hands, and the backs of your neck.
