Truth About Sunscreens and Skin Cancer

 Why You Should But Sunscreens At Health Food Stores

      sunscreens and skin cancer

 We’ve all been warned that sun exposure can cause skin cancer, but that’s only half the story. The fact is that skin cancer was very rare 100 years ago and is still extremely rare among many populations who spend all day in the sun.

Statistically the greatest rise in skin cancer has been in countries where chemical sunscreens have been heavily promoted. There is almost no skin cancer among dark skinned people living in Africa. That’s probably not solely due to skin pigment however because African- Americans have a higher rate of skin cancer and stay in the sun less than their counterparts living in Africa.

 It seems likely that the recent rise in skin cancers is due to factors other just sun exposure. Drs. Cedric and Frank Garland of the University of California believe that increased use of chemical sunscreens is the primary cause of the skin cancer epidemic. Dr. Marianne Berwick epidemiologist of Sloan Kettering Cancer institute concluded after years of study that: “we don’t really know if sunscreens prevent skin cancer at all”. However, everyone needs to know that there are safe alternatives.

 The problem with chemical sunscreens is this: for decades the mainstream media and cosmetic companies have strongly advocated liberal application of chemical sunscreens before any exposure to sunlight, even for young children. This is despite that there has never been adequate safety testing of the primary chemicals in these products. The possible link between sunscreens and skin cancer needs immediate in-depth analysis.

 Many popular chemical sunscreens may actually increase cancer rates. 40% of sunscreens contain topical vitamin A, often listed as retinyl palmitate. Recent government studies have shown that tumors and lesions develop 21% faster when skin coated with vitamin A is exposed to sunlight.

 Most chemical sunscreens contain oxybenzone, a synthetic estrogen. Since the skin is a porous organ, oxybenzone penetrates the skin and contaminates the body. These chemicals can mimic real estrogen, feminize tissues and throw the bodies systems out of balance. Oxybenzone can cause reproductive disorders in men and women and increase incidence of many different kinds of cancers, birth defects and innumerable other serious health problems

Is Sunscreen Really Necessary?

 The answer is: maybe, sometimes. For instance, if you live in a northern climate and take a sun-filled winter vacation your body would not have enough time to gradually tan and build up thicker skin. Or if you have an indoor job and plan to spend the first sunny weekend of the summer outside it would be best to use a safe sunscreen because they help prevent sunburn. If you have time to gradually increase your sun exposure, sunscreen may not be necessary or advisable. Sunscreens definitely reduce vitamin D production and as a result reduce the numerous powerful health benefits natural, sun-created vitamin D provides, including cancer prevention. Take the following steps first before applying sunscreens:

 Wear clothes. Shirts, hats, shorts and pants shield your skin from the sun’s UV rays – and don’t coat your skin with goop. Early in the season a long-sleeved shirt is a good start.

 Find shade – or make it. Picnic under a tree, read beneath an umbrella, take a canopy to the beach. Keep infants in the shade – they lack tanning pigments (melanin) to protect their skin.

 Plan around the sun. If your schedule is flexible, go outdoors in early morning or late afternoon when the sun is lower in the sky. UV radiation peaks at midday, when the sun is directly overhead.

 Don’t get burned. Red, sore, blistered (then peeling) skin is a clear sign you’ve gotten far too much sun. Repeated sunburn increases skin cancer risk. Once the skin turns pink the health benefits of vitamin D production cease.

 When choosing sunscreens you’d be smart to completely avoid those with vitamin A, (retinol or retinyl palmitate) and oxybenzone. Far safer active ingredients are zinc oxide or titanium dioxide. Inactive nourishing ingredients could include coconut oil, jojoba oil, vitamins D and E, sunflower oil, or shea butter. Choose a sunscreen effective against UVA and UVB radiation. I’ve found that one formula from a given manufacturer may be safe while another from the same company has dangerous ingredients. Do your homework or shop at a store that does it for you, then go out for some warm weather fun in the sun.
