Slash Your Risk of Cancer - by Breaking This Cardinal Rule

By Dr. Mercola
UV light from the sun and tanning beds is the main vitamin D source for humans, and researchers have identified an astonishing number of health benefits of vitamin D in the past decade.
But since UV exposure has been suspected of causing skin cancer, many conventional health authorities still warn against it.
A recent review of studies sought to review the health effects of solar radiation, tanning beds and vitamin D.
The researchers looked at data from different time periods for populations at different latitudes, with the aim at looking at the relative risk for cutaneous malignant melanoma associated with tanning bed use, vitamin D and UV effects.
They found that increased tanning bed use was NOT associated with melanoma.
According to the authors:
"Due to the fear of skin cancer, health authorities warn against sun and sunbed exposure.
This policy, as well as the recommended vitamin D doses, may need revision."
And:
"… The overall health benefit of an improved vitamin D status may be more important than the possibly increased [cutaneous malignant melanoma] risk resulting from carefully increasing UV exposure."
In fact, Ivan Oransky, the editor of Reuters Health, has previously noted that the real risk of getting skin cancer from a tanning bed is less than three-tenths of one percent—and even then, this is likely only from those who habitually overexpose themselves.
Sun Exposure and Skin Cancer
The authors of the featured review state that while sun exposure is commonly assumed to be the main cause of cutaneous malignant melanoma (CMM hereafter referred to simply as melanoma, the most lethal form of skin cancer—the matter is actually NOT "settled."
The theory is still under dispute, and in their analysis, they reviewed the arguments for and against causation.
With a hint of irony, the authors state that "several factors are probably involved, as exemplified by a relationship sometimes found between gross domestic product and melanoma incidence." They also list a number of associations between sun exposure and melanoma found in the medical literature, such as:
  • Intermittent sun exposure and severe sunburn in childhood are associated with an increased risk of melanoma
  • Occupational exposure, such as farmers and fishermen, and regular weekend sun exposure are associated with decreased risk of melanoma
  • Sun exposure appears to protect against melanoma on skin sites not exposed to sun light, and melanoma occurring on skin with large UV exposure has the best prognosis
  • Patients with the highest blood levels of vitamin D have thinner melanoma and better survival prognosis than those with the lowest vitamin D levels.
So what about tanning beds—are they more dangerous than regular sun exposure? As you may recall, the Senate's health-care overhaul bill now includes a 10 percent tax on tanning services to dissuade you from engaging in such "health-harming" activities; a move that is unquestionably short sighted and counterproductive considering the fact that vitamin D deficiency is rampant in the U.S.
Where tanning beds are concerned, the science is more conflicted, with some studies finding no detrimental impact from tanning beds on skin cancer rates while others have found that rates of skin cancer are higher in those using tanning beds than those who do not tan. The reason for these conflicting findings, the authors speculate, could very well be due to differences in UVA/UVB ratios and intensities between different types of tanning beds.
What Makes a Tanning Bed Safe?
I believe they're likely correct in their speculation that the type of tanning bed may be a major factor in whether or not it will have a beneficial or detrimental impact on your cancer risk. Safe tanning beds have less of the dangerous UVA than sunlight, while unsafe ones emit more UVA than sunlight, and it is the UVA rays, which penetrate your skin more deeply than UVB, that appear to be a much more important factor in causing photoaging, wrinkles and skin cancers.
Another important factor when selecting a tanning bed is the type of ballast it employs, to avoid excessive electromagnetic field (EMF) exposure. Most tanning units use magnetic ballasts to generate light. These magnetic ballasts are well known sources of EMF fields that can contribute to cancer.
If you hear a loud buzzing noise while in a tanning bed, it has a magnetic ballast system. I strongly recommend you avoid magnetic ballast beds, and restrict your use of tanning beds to those that use electronic ballasts.
High-quality indoor tanning devices are safe if you precisely follow the simple guideline of never getting burned. Your skin should only get the lightest shade of pink after using them. The FDA has very strict guidelines that seem overly restrictive and will likely impair most people from getting enough vitamin D.
The FDA also recommends waiting 24-48 hours between doses. The reason for this is that it takes at least 24 hours for the erythema to go away. This exposure schedule can be described as CONTROLLED SUNSHINE, making it a very safe way to receive the benefits of the sun while indoors. Ideally you should do this also when you are initially exposed to sunshine. But once you have a tan you can easily and safely increase exposure to once a day.
IF Sun Exposure Increases Your Risk of Cancer, Just How Great is that Risk?
Even when looking at the research showing an increased risk for skin cancer from sun exposure, just how great is that risk? Ivan Oransky, M.D., editor of Reuters Health wrote an excellent commentary on this last year.
Each year, during the month of May, as the sun slowly begins to thaw away those winter blues, you start getting bombarded with Skin Cancer Awareness ads; all of which pitch the idea that the sun is your enemy. Many will include the statistic issued by the World Health Organization, which states that "use of sunbeds before the age of 35 is associated with a 75 percent increase in the risk of melanoma."
Sounds horrific, but how real is this threat?
"[W]hat does that really mean? Is it 75 percent greater than an already-high risk, or a tiny one?" Oransky writes.
"If you read the FDA's "Indoor Tanning: The Risks of Ultraviolet Rays," or a number of other documents from the WHO and skin cancer foundations, you won't find your actual risk. That led AHCJ member Hiran Ratnayake to look into the issue in March for The (Wilmington, Del.) News Journal, after Delaware passed laws limiting teens' access to tanning salons. The 75 percent figure is based on a review of a number of studies, Ratnayake learned. The strongest such study was one that followed more than 100,000 women over eight years.
But as Ratnayake noted, that study "found that less than three-tenths of 1 percent who tanned frequently developed melanoma while less than two-tenths of 1 percent who didn't tan developed melanoma." That's actually about a 55 percent increase, but when the study was pooled with others, the average was a 75 percent increase.
In other words, even if the risk of melanoma was 75 percent greater than two-tenths of one percent, rather than 55 percent greater, it would still be far below one percent." [Emphasis mine.]
So, while statistically true, it's really misleading, and incites undue fear. By only presenting the relative risk increase (the 75 percent increase) they make the risk sound rather unreasonable. Meanwhile, your absolute risk of developing skin cancer from sun exposure is still, AT WORST, below one percent! And please remember, these highly distorted scare tactics fail to mention the BENEFITS of the exposure, which radically reduce the dangers of the far more common, breast, prostate and colon cancers that are reduced.
Understanding the Difference between Relative Risk and Absolute Risk
Oransky explains the importance of understanding the difference between relative risk and absolute risk in his article:
"Absolute risk just tells you the chance of something happening, while relative risk tells you how that risk compares to another risk, as a ratio. If a risk doubles, for example, that's a relative risk of 2, or 200 percent. If it halves, it's 0.5, or 50 percent. Generally, when you're dealing with small absolute risks, as we are with melanoma, the relative risk differences will seem much greater than the absolute risk differences.
You can see how if someone is lobbying to ban something – or, in the case of a new drug, trying to show a dramatic effect – they would probably want to use the relative risk. … So when you read a study that says something doubles the risk of some terrible disease, ask: Doubles from what to what?"
Tanning Beds Decrease Ten Times More Cancers than they Cause
Another important factor to keep in mind is that vitamin D, ideally from sun exposure, may decrease your risk of many other cancers and chronic diseases.
According to the featured review:
"… it can be estimated that increased sun exposure to the Norwegian population might at worst result in 200-300 more melanoma deaths per year, but it would elevate the vitamin D status by about 25 nmol/l and might result in 4,000 fewer internal cancers and about 3,000 fewer cancer deaths overall.
The lack of sunlight exposure leads to more health problems than bone disease and increased risk of cancer. Other benefits include protection against infectious diseases and non-cancerous diseases (diabetes, CVD, multiple sclerosis, and mental disorders)."
Overall, I believe the less than one percent risk of developing skin cancer from sun exposure or a safe tanning bed is well worth it, as increased vitamin D levels will protect you against so many other debilitating and lethal diseases and cancers… There's also compelling research showing that sun exposure will indeed protect you against melanoma—the most dangerous form of skin cancer.
Sun Exposure is the BEST Way to Optimize Your Vitamin D Levels
In my view, a safe tanning bed comes in as a close second after natural sun exposure as the ideal way to optimize your vitamin D levels (as opposed to getting it from fortified food items or supplements). In a recent interview, Dr. Stephanie Seneff explained how vitamin D—specifically from sun exposure—is intricately tied to healthy cholesterol and sulfur levels, making the recommendation to get your vitamin D from the sun all the more important.
To review the details, please listen to the interview below.

As a quick summary, when you expose your skin to sunshine or a safe tanning bed, your skin synthesizes vitamin D3 sulfate. This form of vitamin D is water soluble, unlike oral vitamin D3 supplements, which is unsulfated. The water soluble form can travel freely in your blood stream, whereas the unsulfated form needs LDL (the so-called "bad" cholesterol) as a vehicle of transport. Her suspicion is that the oral non-sulfated form of vitamin D may not provide all of the same benefits as the vitamin D created in your skin from sun exposure, because it cannot be converted to vitamin D sulfate.
I believe this is a very compelling reason to really make a concerted effort to get ALL your vitamin D requirements from exposure to sunshine, or by using a safe tanning bed. If neither of these are feasible options, then you should take an oral vitamin D3 supplement.
Carole agrees that sun exposure is ideal as it may also provide other health benefits. Lack of sun exposure now appears to be at the very root of many common health problems, which strict sun-avoidance has progressively made worse. Vitamin D deficiency is, after all, a fairly recent health concern, historically speaking.
"I think it is obvious that the reason we have this deficiency is because we have become an industrialized nation," she says. "… What we've done is we've come inside. We cover up. Even in San Diego where I live, when they measured my level it was 18 ng/ml.
When we did a scientific test of what it's going to take to get enough sun in San Diego… at my age – age is a factor in how much you absorb – we came to a test conclusion that it was going take 15 to 20 minutes a day in the prime time of UV, between 10 am and 2 pm, each and every day… with 40 percent of my body exposed. … I encourage people to take advantage of the sun. The only message I have about the sun is: don't burn. That's it."
<h2>How Vitamin D Performance Testing Can Help Optimize Your Health

</h2>
Additionally, a robust and growing body of research clearly shows that vitamin D is absolutely critical for good health and disease prevention. Vitamin D affects your DNA through vitamin D receptors (VDRs), which bind to specific locations of the human genome. Scientists have identified nearly 3,000 genes that are influenced by vitamin D levels, and vitamin D receptors have been found throughout the human body.
Is it any wonder then that no matter what disease or condition is investigated, vitamin D appears to play a crucial role? This is why I am so excited about the D*Action Project by GrassrootsHealth. It is showing how you can take action today on known science with a consensus of experts without waiting for institutional lethargy. It has shown how by combining the science of measurement (of vitamin D levels) with the personal choice of taking action and, the value of education about individual measures that one can truly be in charge of their own health.
In order to spread this health movement to more communities, the project needs your involvement. This is an ongoing campaign during the month of February, and will become an annual event.
To participate, simply purchase the D*Action Measurement Kit and follow the registration instructions included. (Please note that 100 percent of the proceeds from the kits go to fund the research project. I do not charge a single dime as a distributor of the test kits.)
As a participant, you agree to test your vitamin D levels twice a year during a five year program, and share your health status to demonstrate the public health impact of this nutrient. There is a $65 fee every 6 months for your sponsorship of the project, which includes a test kit to be used at home, and electronic reports on your ongoing progress. You will get a follow up email every six months reminding you "it's time for your next test and health survey."

Re: Slash Your Risk of Cancer - by Breaking This Cardinal Rule

This is very long and I know many of you may be tempted to skip it.

But if you are a tanning salon owner - You MUST read and understand this article!!!!!!


Don't worry too much about his "pitching" of his "safe" tanning beds he sells.

Instead, focus on the notion of "relative vs absolute risk" and the health benefits of strong Vitamin D readings and their relation to good health.

This is MUST READING for every tanning salon owner - and all your staff. Read it to them/break it down if you have to. But this is a pretty straight-to-the-point summary. Might even be worth having on hand for customers who express "concern" about tanning.

Yes, if magnetic ballasts are a serious risk, we are all in deep do do; almost every commercial overhead light in every building in the US has magnetic ballasts in them.

Re: Slash Your Risk of Cancer - by Breaking This Cardinal Rule

Doctors and health authority nuts, still to date don't know exactly what causes cancer. Most of them will spew ******** to scare you into going those expensive chemo therapies. which is like fighting fire with fire.

The human body is a biological machine, it can adapt to sunlight and other stimuli without getting cancers and all(it has done so for millions of years). the body itself has self repair mechanisms in DNA.
also if cancer was guaranteed with sunlight and UV exposure, then farmers would die off from the face of the earth. its something else that's killing people from cancer, not sunlight!
