Maleth, the quote I provided isn't to insinuate that Caucasians don't get skin cancer more often. The recent study does say that those with more melanin that contract melanoma are more fatal.
Now regarding sunscreen. More research is coming out that show sunscreen will keep us from burning and reduce the amount of UV penetration into our DNA (what causes the cancer) that it's actually causing cancer. I would assume Caucasians use sunscreen much more than those who have melanin. So could be one of many contributions to inflated cancer rates in caucasians.
Dermatologists and medical professionals blame the sun for the increase in skin cancer because it is the largest source of ultra violet radiation (UV). However, many leading-edge doctors and health experts contradict popular dogma about the sun being the main cause of skin cancer.
Lifestyle and diet play a bigger role than sun exposure when it comes to getting skin cancer. Bernard Ackerman, MD, the founding father of dermatopathology, who specializes in the study of cutaneous diseases at a microscopic and molecular level. He’s concluded that evidence that the sun causes skin cancer is inconsistent and inconclusive. “While some studies do show a small association, he says, others show none.”
In addition, a 2004 study in the medical journal The Lancet showed indoor workers were twice as likely to get skin cancer as those who spent more time in the sun: “Paradoxically, outdoor workers have a decreased risk of melanoma compared with indoor workers, suggesting that chronic sunlight exposure can have a protective effect.”
Lack of sunlight means lack of vitamin D, which is a necessary nutrient for the body’s immune system to function properly. Low vitamin D levels are linked to health problems, including cancer. Appropriate sun exposure helps maintain adequate levels of vitamin D. Using sunscreen interferes with that exposure and could be contributing to the rise in skin cancer.
Sunscreen prevents sunburn by blocking UVB rays thus disabling the skin, allowing us to be in the sun longer than what is natural. Most major brands of sunscreen block UVB while allowing UVA, which actually causes more damage to the skin. In addition, UVB is required to produce vitamin D, so blocking it seems contradictory to good health and cancer prevention.
Sunscreen often contains cancer-causing chemicals that bake into the skin and get absorbed into the bloodstream, over-taxing the liver with toxins. Here are some of the offenders:
OMC – The main chemical used in sunscreens to filter out UVB is octyl methoxycinnamate (aka “OMC”) which has been shown to kill mouse cells even at low doses. Plus, it was also shown to be particularly toxic when exposed to the sun. And guess what? OMC is present in the vast majority of sunscreen brands!
Titanium dioxide – another common ingredient in sunscreens, has been classified as “a potential occupational carcinogen” by the National Institute for Occupational Safety and Health.
Oxybenzone – oxybenzone becomes carcinogenic when exposed to the sun and has been found to be a hormone disruptor! The Environmental Working Group (EWG) recommends consumers avoid oxybenzone, and yet it remains in many major brands of sunscreen.
Derivatives of vitamin A such as retinol and retinyl palmitate – AOL News reported that about half the sunscreens tested in a study contained derivatives of vitamin A such as retinol and retinyl palmitate. These ingredients have been found to be photocarcinogenic by the FDA’s own studies, meaning the ingredients become toxic and cancer causing when exposed to sunlight.
Diesopropyl adipate – in 2006, the National Toxicology Program reported that diesopropyl adipate, another ingredient in many sunscreens, increased the incidence of tumors in laboratory animals.
In addition, there are many more questionable chemicals in sunscreen never proven to be safe or effective for use on the skin. Andreas Moritz, a leading practitioner in the field of alternative and integrative medicine, goes so far as to state, “Sunscreen is the leading cause of skin cancer.”
