Skin Cancer Prevention

According to www.skincancer.org, about 90% of non-melanoma skin cancer and 86% of melanomas are associated with exposure to the sun’s ultraviolet rays (UV). UV exposure damages the skin’s DNA which can skin cancer. Sun damage is cumulative and increases your lifetime risk of skin cancer. Even one blistering sunburn in childhood or adolescence doubles the risk of developing melanoma. 

• Avoid the sun from 10-4pm daily
• Avoid tanning which is also a sign of sun damage
• Choose a sun screen labeled ” Broad Spectrum” which means it protects against UVA and UVB light and is water resistant
• Cover up. Wear a hat and long sleeves, and sunglasses that block UV rays.
• Seek shade
• Perform monthly self-exams
• Get an annual screening
• Eat a healthy diet that contains foods high in antioxidants that can help to prevent skin cancer. These antioxidants have been shown to prevent skin cancer- Vitamins C, E and A, zinc, selenium, beta carotene, omega 3 fatty acids, lycopene and polyphenols.
• A recent development is the finding that common skin cancers and precancerous lesions can be prevented with the use of a Vitamin B3 supplement called nicotinamide. Studies show that taking a nicotinamide supplement twice a day cut the rate of new squamous cell and basal cell cancers by 23% in people at high risk for skin cancer.
• Studies show drinking one or more cups of caffeinated coffee daily can reduce your risk for melanoma and non-melanoma skin cancer.
• Keep newborns out of the sun. Use a physical sunscreen made for babies, only after six months of age.
• Some topical and oral medications cause sun sensitivity and increase your risk for sunburn. 

Sunscreen can prevent sunburn and photoaging, age spots, melasma, and dark spots left after acne and psoriasis, and reduce your risk for skin cancer. The best sun protection is from a product that offers an SPF 30 or higher, is broad-spectrum and water resistant. Apply on all exposed skin. Reapply after swimming or water sports

A chemical sunscreen is absorbed into the skin and works by absorbing the UV rays and converting them to heat which is released by the skin. A physical sunblock deflects the sun’s rays. It contains zinc oxide or titanium oxide and is gentle enough that it can be used on children. If you have rosacea, use a physical sunscreen only. A combination of both types offers the best protection.
