Skin cancer is the abnormal growth of skin cells most often developed on the skin exposed to the sun, But this common form of cancer can also occur on areas of your skin not ordinarily exposed to sunlight.
CAUSES OF SKIN CANCER
- Melanocytes: which produce melanin, the pigment that gives skin its normal color are located in the lower part of your epidermis, Melanocytes produce more melanin when you’re in the sun to help protect the deeper layers of your skin.
- Squamous cells: lie just below the outer surface and function as the skin’s inner lining.
- Basal cells: which produce new skin cells, sit beneath the squamous cells.
PREVENTIONS OF SKIN CANCER
- Check your skin regularly and report changes to your doctor: Examine your skin often for new skin growths or changes in existing moles, freckles, bumps and birthmarks.
With the help of mirrors, check your face, neck, ears and scalp, Examine your chest and trunk, and the tops and undersides of your arms and hands. Examine both the front and back of your legs, and your feet, including the soles and the spaces between your toes. Also check your genital area and between your buttocks.
2. Avoid tanning beds: Lights used in tanning beds emit UV rays and can increase your risk of skin cancer.
3. Wear protective clothing: Sunscreens don’t provide complete protection from UV rays. So cover your skin with dark, tightly woven clothing that covers your arms and legs, and a broad-brimmed hat, which provides more protection than a baseball cap or visor does.
4. Avoid the sun during the middle of the day: For many people in North America, the sun’s rays are strongest between about 10 a.m. and 4 p.m. Schedule outdoor activities for other times of the day, even in winter or when the sky is cloudy.
You absorb UV radiation year-round, and clouds offer little protection from damaging rays, Avoiding the sun at its strongest helps you avoid the sunburns and suntans that cause skin damage and increase your risk of developing skin cancer, Sun exposure accumulated over time also may cause skin cancer.
