SUNSCREEN: CAUSES CANCER OR PROTECTS AGAINST IT………………
BILL COUZENS, FOUNDER LESSCANCER.ORG
No one doubts that excessive sun exposure can cause skin cancer. The question is, does sunscreen prevent it?
The sun’s ultraviolet (UV) rays damage the skin by either prematurely aging or burning it. The type of damage is determined by the wavelength of the light rays, but both forms of damage can lead to skin cancer. To prevent said damage (and cancer), doctors, aestheticians, and moms everywhere recommend wearing sunscreen.
Theoretically, sunscreens offer various SPF, or “sun protection factor”. The SPF rating you select should equal to the number of minutes you plan to be in the sun divided by the number of minutes it takes for your skin to redden naturally with a minimum of SPF 15.
Unfortunately, sunscreen may be causing more harm than good in two ways. First, the SPF may be giving people a false sense of safety. A recent study by the Environmental Working Group (EWG), a non-profit and consumer advocacy group, indicates that up to 87% of sunscreens do not provide adequate sun protection.
Second (and arguably more disconcerting), some ingredients found in sunscreens like oxybenzone are designed to protect the skin but may be harming it, according to a study by the US Center for Disease Control(CDC).
Oxybenzone is derived from benzophenone and used in hundreds of skincare products from sunscreens to lip balms. However, oxybenzone has ability to penetrate the epidermal/dermal junction, where it can actually cause (not prevent) free radical damage that may lead to cancer.
The body does have a natural defense against UV damage. It increases the production of a pigment called melanin (aka “a tan”). But according to the CDC’s Farm Bureau Safety Program, “[E]ven the darkest skin doesn’t contain enough melanin to prevent damage from exposure to the sun.”……………..SEE LINK http://www.huffingtonpost.com/lauren-fornes/sunscreen-causes-cancer-_b_93916.html
