Exposing the Truth about Tanning and the World's Most Common Cancer


Exposing the Truth about Tanning and the World's Most Common Cancer

By: Danielle White
It is official. Spring has sprung, bringing along with it spring fever. I can see it in my students' eyes. They are practically breaking out in hives itching to soak up the warm spring sun, despite the fact they are sitting in a class that discusses skin cancer prevention.

Alas, despite their instructor's desperate pleadings, these 20-something-year-old college students find it difficult, if not arduous, to forego their so-called "need to tan" that Hollywood constantly feeds and propagates. And while it is quite simply impossible for anyone to get a "safe tan" from tanning beds and other forms of ultraviolet radiation, there are several high-quality sunless tanning mousses that not only achieve that coveted bronze look, naturally, but also provide essential sun protection. Now my students, even my pageant girls, can have the best of both worlds.

They no longer have to walk into class with guilt-ridden faces knowing they have completely disregarded the very real dangers associated with using tanning beds. They are happy and healthy. And that makes me, the now dubbed "skin cancer crusader" happy, too.

Yet, despite the fact I am slowly replacing their love for tanning with a safe alternative-that of sunless tanning foams such as those developed and manufactured by Neostrata (which garnered the prestigious Gold Triangle Award from the American Academy of Dermatology in 2005), there remains a deeply pressing concern; a lingering question. How do we educators and advocates effectively tackle the culture of tanning, and thus significantly reduce the alarming increase in skin cancer incidence and mortality as a result of frequenting tanning salons?

Contrary to popular belief, the bottom-line is that there is no such thing as a "safe" tan. Any tan is damage to your skin. And that is a fact. The Indoor Tanning Association (ITA) would have the consumer-driven pop culture hold to the myth that tanning beds are safe, and are even a viable way of treating a variety of skin issues such as acne, or even Seasonal Affective Disorder. Such claims are false, even irresponsible and potentially deadly, and credible scientific research proves it. There is no way to achieve a safe, healthy tan from tanning beds or other sources of ultraviolet radiation.

Consider the following case-and-point.

The American Academy of Dermatology, in conjunction with the Centers for Disease Control and Prevention (CDC) recently conducted a lengthy and independent research study which sheds some light on this issue, thus proving valuable insight into a media-inundated industry wrought with misleading, confusing, and even erroneous claims about tanning. They discovered, through numerous surveys, that more than 61% of women 18 and older (and 69% of men) equate a tan with beauty and health (www.aad.org/aad/Newsroom).

Despite the fact that we know that there is no such thing as a safe tan, people still associate bronzed skin with beauty and health," said Dr. Darrel S. Rigel, clinical professor at New York University Medical Center. "What's even more surprising is that the survey showed that 62 % of men and women responded that they know someone who has or had skin cancer, which - depending on its location and severity - does nothing to improve your looks and can be very detrimental to your health."

Dr. Elizabeth Whitmore, who, like Dr. Rigel, is a member of the AAD, agrees. "People continue to invest both time and money into visiting tanning salons despite evidence which have found an increased incidence of melanoma-the deadliest form of skin cancer- in those who visit indoor tanning salons." Joyce Ayoub, director of public information at the Skin Cancer Foundation further attests to this fact. "There is a myth that people like to believe, but it is a myth; not fact. Any tan means damage to the skin."

Further illustrating this point is a study headed by a team of scientists and researchers at Johns Hopkins School of Medicine. These researchers discovered that the use of tanning beds and artificial tanning light sources-even just once, can, indeed, lead to molecular changes in the skin that may lead to cancer. "In comparing the effects of a teenager who was exposed for the first dose of tanning beds to multiple doses [... ] it is evident that there is damage sustained to the molecular structure of the skin even having only been exposed once," Whitmore says.

The researchers at Johns Hopkins, who conducted the study of 10 teenagers who were exposed to full-body tanning beds over a period of two weeks which, she says was similar to the routine "a teenager preparing for prom or for a tropical vacation" would undertake. The researched found that the subjects' skin and blood, (which was carefully analyzed both prior to the UV exposure and after the exposure) had two distinct markers that indicated molecular change.

Whitmore adds, "It's another indication that there is biologic activity and that there is cell damage when the skin is exposed to UV rays. This repair process can eventually fail to do its job completely or correctly causing the cells to replicate abnormally [...] this breakdown in the normal functioning of cells can lead to malignant cancer."

In actual fact, the AAD asserts that nearly 90% of skin carcinomas are a result of over-exposure to UV rays. Thusly, The Cancer Crusaders Organization (www.cancercrusaders.org) randomly surveyed college-aged students (18-to-25), and found that nearly 100% reported to having used a tanning bed at least once in their lifetime.

After having been apprised of the risks and dangers associated with tanning, many were undeterred. "Not only does tanning help my acne, it helps me a lot during this time of year when there's a great deal of pressure with upcoming finals and during the stresses of the holidays," says Amanda Gusciano, a senior Brigham Young University. "Even though, I am aware of the dangers of tanning, there is still that temptation; I haven't stopped using tanning beds and I never use sunscreens."

The significance protecting your skin from the harmful affects of UV-B and UV-A rays goes almost without saying; however, I emphasize it emphatically to both my students and especially to my pageant contestants. UV-B and UV-A rays have varied affects on your skin, your immune system, and your body as a whole. UV-B irradiation disrupts the melanocytes, causing them to release the "redness" known as sunburn. Any change in the color of your skin as a result of over-exposure to the sun is damage to your skin, even if your skin tends to "tan" as opposed to burn.

All changes in the color of your skin as a result of UV exposure is the melanocytes in your skin (the cells responsible for pigmentation) trying to tell you that normal, healthy cells have been severely disrupted. Have you ever left basketball outside in the hot summer sun for a lengthy period of time? And after you retrieved the ball, you immediately notice that the elasticity of the ball is weakened-it feels "rubbery" and never quite "bounces back"? This is exactly what happens to your skin as a result of prolonged UV exposure. Both UV-B and UV-A rays have cumulative effects and coupled together can lead to melanoma skin cancer.

In sum, if you must heed the need to be golden, opt for sunless tanning mousses. There are quality dermatologically-approved sunless tanning mousses available that are reasonably priced, and will give you evenly distributed color, but will do it without the harmful affects of UV-rays. Now you can have the best of both worlds- good looks and good health.

Diseases Caused by Smoking - Surgeon General's Report Expands List


Diseases Caused by Smoking - Surgeon General's Report Expands List

By: Martin Popham
U.S. Surgeon General Richard H. Carmona today released a new comprehensive report on smoking and health, revealing for the first time that smoking causes diseases in nearly every organ of the body. Published 40 years after the surgeon general's first report on smoking -- which concluded that smoking was a definite cause of three serious diseases -- this newest report finds that cigarette smoking is conclusively linked to diseases such as leukemia, cataracts, pneumonia and cancers of the cervix, kidney, pancreas and stomach.
"We've known for decades that smoking is bad for your health, but this report shows that it's even worse than we knew," Dr. Carmona said. "The toxins from cigarette smoke go everywhere the blood flows. I'm hoping this new information will help motivate people to quit smoking and convince young people not to start in the first place."
According to the report, smoking kills an estimated 440,000 Americans each year. On average, men who smoke cut their lives short by 13.2 years, and female smokers lose 14.5 years. The economic toll exceeds $157 billion each year in the United States -- $75 billion in direct medical costs and $82 billion in lost productivity.
"We need to cut smoking in this country and around the world," HHS Secretary Tommy G. Thompson said. "Smoking is the leading preventable cause of death and disease, costing us too many lives, too many dollars and too many tears. If we are going to be serious about improving health and preventing disease we must continue to drive down tobacco use. And we must prevent our youth from taking up this dangerous habit."
In 1964, the Surgeon General's report announced medical research showing that smoking was a definite cause of cancers of the lung and larynx (voice box) in men and chronic bronchitis in both men and women. Later reports concluded that smoking causes a number of other diseases such as cancers of the bladder, oesophagus, mouth and throat; cardiovascular diseases; and reproductive effects. Today's new report, The Health Consequences of Smoking: A Report of the Surgeon General, expands the list of illness and conditions linked to smoking. The new illnesses and diseases are cataracts, pneumonia, acute myeloid leukemia, abdominal aortic aneurysm, stomach cancer, pancreatic cancer, cervical cancer, kidney cancer and periodontitis.
Statistics indicate that more than 12 million Americans have died from smoking since the 1964 report of the surgeon general, and another 25 million Americans alive today will most likely die of a smoking-related illness.
The report's release comes in advance of World No Tobacco Day, an annual event on May 31 that focuses global attention on the health hazards of tobacco use. The goals of World No Tobacco Day are to raise awareness about the dangers of tobacco use, encourage people not to use tobacco, motivate users to quit and encourage countries to implement comprehensive tobacco control programs.
The report concludes that smoking reduces the overall health of smokers, contributing to such conditions as hip fractures, complications from diabetes, increased wound infections following surgery, and a wide range of reproductive complications. For every premature death caused each year by smoking, there are at least 20 smokers living with a serious smoking-related illness.
Another major conclusion, consistent with recent findings of other scientific studies, is that smoking so-called low-tar or low-nicotine cigarettes does not offer a heath benefit over smoking regular or "full-flavor" cigarettes.
"There is no safe cigarette, whether it is called 'light,' ultra-light,' or any other name," Dr. Carmona said. "The science is clear: the only way to avoid the health hazards of smoking is to quit completely or to never start smoking."
The report concludes that quitting smoking has immediate and long-term benefits, reducing risks for diseases caused by smoking and improving health in general. "Within minutes and hours after smokers inhale that last cigarette, their bodies begin a series of changes that continue for years," Dr. Carmona said. "Among these health improvements are a drop in heart rate, improved circulation, and reduced risk of heart attack, lung cancer and stroke. By quitting smoking today a smoker can assure a healthier tomorrow."
Dr. Carmona said it is never too late to stop smoking. Quitting smoking at age 65 or older reduces by nearly 50 percent a person's risk of dying of a smoking-related disease.
