Skin cancer detection month ended in May, but that doesn't mean it's time to stop being wary of the dangers of skin cancer. Taking good care of your skin is vital during the bright sunny days of summer. Yahoo health reports, "according to the Skin Cancer Foundation, adults who use sunscreen with SPF 16 and above can cut their risk of developing melanoma, the deadliest form of skin cancer, in half."
Using sunscreen and using it properly is vital in protecting yourself from skin cancer. Consumer Reports found that unfortunately many sunscreens don't actually provide the SPF they promise when they come into contact with water. In fact the FDA has limited the use of the term "waterproof" on many sunscreen products. What is SPF and how do you find a high SPF sunscreen? Click ahead for more information on this common term.
SPF stands for sun protection factor. It is an imperfect measurement. According to the UCSF school of medicine, the SPF rating is a measure of "how long a sunscreen remains effective on the skin." The effectiveness of a sun block can be determined "by multiplying the SPF factor by the length of time it takes for him or her to suffer a burn without sunscreen." Thus, if a person develops a sunburn in 10 minutes when not wearing a sun block, the same person will prevent sunburn for 150 minutes if he/she wears a sun block with a SPF of 15. Consequently, SPF 100 is not twice as strong as SPF 50-- it's about 1% as strong.
With this information it's important to use a high SPF, and follow all directions associated with use to adequately protect your skin from the sun. But that's not all you can do. The Skin Cancer Foundation recommends that everyone do a monthly self-examination of their skin to look for any changing or new lesions. These may be early-stage skin cancer, and can be easily removed and therefore easy to prevent.
Unfortunately invisible damage and skin aging are also caused by ultraviolet light which does not cause skin reddening or pain. Conventional sunscreen blocks very little ultraviolet radiation relative to the SPF. UV light has been found to increase the risk of melanoma. The best and only protection for this type of sun exposure is to cover up with hats, shirts, and sleeves.
Take good care of your skin this summer, check often for early signs of melanoma, and see yourdermatologist if you have any questions or concerns.
