THE US-FDA has issued a warning on the use of tanning beds at home and at tanning salons: tanning increases the risk for melanoma, a deadly skin cancer, up to 59 percent! More than 2.5 million teens, mostly girls, use tanning booths each year in the United States. Just like with poison, the more exposure, the more sessions, the higher the risk.
The data are from the National Health Interview Survey’s Cancer Control Supplement, published in the CDC’s Morbidity and Mortality Weekly Report. The World Health Organization has also determined that UV rays from tanning beds cause cancer.
The second most common cancer, melanoma has the following 5-year survival rates: About 95 percent for Stage IA, when diagnosed early, and between 5 to 20 percent for stage IV, when it has already spread to other organs.
Amazingly UV rays emitted from tanning beds are up to 15 times greater (deadlier) than the rays from the sun.
Melanoma kills one person every 50 minutes, or about 28 every day. And these are useless and preventable deaths!
Let us review some facts about sunlight and its harmful UV rays.
What in sunlight is beneficial and harmful to us?
The sun and its light are not only beautiful but vital to our life and survival on this planet. Without the sun, we will be frozen to death, and life forms on earth will cease to exist as we know it today. About 75% of our body’s supply of Vitamin D is generated by our skin’s exposure to sunlight (UV-B rays in particular). Abnormally low blood level of Vitamin D increases the risk of colon and breast cancers and may also speed up .the growth of an existing or early melanoma. Of course, Vitamin D can be taken by mouth. The harmful effects of sunlight comes from its ultraviolet (UV) radiation. which could be dangerous to our health in more ways than one, depending on the amount of exposure and dose that a person gets.
What are the sun-related diseases of the eye?
Cataracts (cloudiness of the lens), which, in severe forms, could cause blindness, especially exposure to UV-B radiation; macular degeneration, the major cause of impaired vision in the USA for people older than 55; photokeratitis, a reversible sunburn of the cornea, also from excessive exposure to UV-B; pterygium, growth of pinkish tissues on the whites of the eye, which may spread on the clear cornea and block vision. This results when one has prolonged sun exposure on the beach or snow without eye protection, and can be very painful for 1-2 days, with temporary blindness. Even with eye cover, the high dose of UV rays from a tanning bed is still very harmful to vision. A nice tan is too high a price to pay for blindness, much less cancer.
How about adverse affects on the skin?
Excessive exposure to UV rays predisposes one to skin cancer, which includes the face and the eyelids, besides skin in other parts of the body. There are three major types of cancers of the skin: Basal Cell Carcinoma, the most common one, Squamous Cell Carcinoma, second most common, and Malignant Melanoma, the most deadly, but fortunately, the rarest. Malignant Melanoma spreads easily and is often deadly if not caught early.
How prevalent are skin cancers?
This is an epidemic and is a global phenomenon. In 1978, in the United States alone, there were 480,000 cases of non-melanoma skin cancers, rising to over one million in 1994, with a growth rate of 7% per year. In Canada, from 1970-1986, melanoma frequency rose 6% per year for men and 4.6% per year for women. Australia has the highest incidence of melanoma in the world. It is said that by age 75, two out of three Australians will have been treated for some type of skin cancer. In the United States, the estimated 30,000 cancer deaths each year could be prevented if Americans, who love sunbathing, do not over-expose themselves to the sun.
How do we protect ourselves from UV radiation?
First and foremost, let us not intentionally expose ourselves to UV rays, through tanning salons (a costly way) or via the sun (for free). Just like anything in life, moderation is the key when it comes to the sun. Tanning beds must be avoided at all cost. While Americans laugh at Asian women when the latter stay under the shade or umbrella on the beach, they also recognize that Asian women’s complexions look more youthful, with less wrinkles, and that Asian women look younger in general, compared to Caucasian females. Asian women also have lower incidence of sun-related diseases.
Since UV radiation comes not only from the sun but is reflected from the ground, snow, sand, water and other reflective surfaces, the use of wide-brimmed hats or caps will reduce UV radiation to the eyes by 50%. Wraparound UV-absorbing eyewear provides the greatest protection, because it also limits radiation from the peripheral rays.
Polarized sunglasses or transition lenses reduce glare but do not, by themselves, provide protection from UV radiation.
Sunglasses, and or prescription lenses, that absorb 99-100% of the full UV spectrum to 400 nm are the best for babies, children and adults. Labels on sunglasses should be closely scrutinized to make sure that they say the lenses absorb 99-100% of both the UV-B and UV-A. If they do not have labels, do not buy them. Consumers must be cautious when the label claims the lenses “block harmful UV” but does not specify how much.
For skin cancer protection, do not rely on sunscreen skin lotion. The best is not to sunbathe for more than 15 to 20 minutes, and apply “physical” sunscreen lotion. Wear protective clothing and a wide-brimmed hat when you go outside during sunny days. Avoid sun exposure between 10 a.m. and 3 p.m., if possible. Also, it has been shown that taking vitamins C, D and E and selenium protects against the damage caused UV rays by lessening the adverse effects of the UV rays on the immune system.
If one must absolutely be out in the sun, he/she must wear a “physical” sunscreen with an SPF of 15, which contains titanium dioxide, zinc oxide or talc. “Physical” sunscreen works by reflecting the UV radiation rather than absorbing the sunscreen into the skin. Doubling the amount of the lotion, or re-applying it later in the day, does not confer added protection. The best is to minimize sun exposure to a safe
degree. Tanning beds are dangerous and must be avoided.
Lastly, if you develop any skin spots or notice any mole in your body to be growing larger or darker, or feel any lumps in your body, consult your physician without delay. If treated early and caught in time, most skin cancers are curable.
To our legislators and civic leaders: Tanning beds and tanning salons must be banned to protect the public from the unconscionable, greedy and reckless entrepreneurs out to rob ignorant people of their hard-earned money while exposing them to cancer and death.
