Exposing the Sunlight/Melanoma Fraud: Part 2

--
Is the purported increase in melanoma a fraud?

In the last post, I made a case that sunlight does not cause melanoma, and that if Melanoma is increasing, as stated by the Melanoma International Foundation (MIF), it is doing so while sunlight exposure is decreasing. But suppose that the increase in melanoma is not an increase at all? Some believe that there is no proliferation of melanoma, but only a proliferation of dermatologists, and a proliferation of diagnoses of skin spots as being melanoma by some dermatologists in an attempt to make more money. An article by Harmon Leon,[1] writing for the Huffington Post, served as a reminder of the potential for fraud among (unscrupulous) dermatologists. I strongly suggest you read that article. I am indebted to Mr. Leon for a few of the points made in this post.

I do not mean to suggest that all dermatologists are dishonest. Many of the facts that I gather are derived from research performed by dermatologists who are trying to awaken the public to the fraudulent actions of some members of their profession.

Those who profit from scare tactics regarding melanoma I call The Powers of Darkness. They have frightened us away from the sunlight, or as Dr. Michael Holick (an honest dermatologist) says, “scared the daylights out of us to scare us out of the daylight.” The consequence is widespread vitamin D deficiency that has led to millions of cases of death and disability.
Dr. Arthur Rhodes, a dermatologist, wrote in a 2003 editorial for an independent dermatology newspaper[2] that melanoma’s public message—that sunlight was the sole cause of melanoma—was causing death among patients and medical professionals alike. In it he suggested that many people were not taking care of melanomas that occurred in areas of little or no sunlight exposure; this was because they assumed that only sunlight could cause melanoma. The following are some of the examples that he gathered from his experience with this most deadly of skin cancers:

1. A dermatology trainee died of melanoma at age 28. He watched a mole change in his armpit for years, but because that area never received UV light, he assumed it was not melanoma and delayed seeking help.
2. A 40-year-old woman had a sore on the bottom of her heel and believing only sunlight caused melanoma, she had no idea that it was melanoma. She died three years later.
3. A Harvard-trained lung specialist ignored a sore on his upper back. He and his fiancée, a Harvard-trained pediatric resident, observed the change for several years without having it examined. They didn’t know that melanoma could occur in an area that never received sunlight. He died six months after diagnosis at age 29.

Here is a quote from this enlightened dermatologist:
“If a medical resident can misinterpret public health messages about sun exposure and melanoma, and two Harvard-trained physicians were ignorant about the most important risk factors for developing melanoma, then the general public will tend to make the same potentially fatal mistakes. Those mistakes lead to delayed diagnosis of this potentially lethal cancer—particularly when we pound out the message that the culprit in melanoma is sun, sun, sun, and we are not sufficiently emphasizing the most important risk factors for developing melanoma.”

Dr. Rhodes states that “melanoma is a heterogeneous disease with multiple causes, arising from potential precursor moles that have little or nothing to do with sun exposure [emphasis mine], including dysplastic nevi, congenital nevi, and abnormal moles on acral surfaces and mucous membranes.”

Another celebrated dermatologist, Dr. Bernard Ackerman, wrote a meticulously documented 440 page monograph called The Sun and the “Epidemic” of Melanoma: Myth on Myth.[3] In it he presents nearly every piece of research regarding sunlight and melanoma up until 2008, and concludes that the purported "epidemic" of sunlight-caused melanoma is a myth.

I agree with these dermatologists. The “epidemic” of melanoma is a myth, and dermatologists themselves are paying a price. Their own sunlight avoidance is causing widespread vitamin D deficiency among members of their profession. Australian dermatologists, while living in one of the sunniest areas of the world, have an average blood-vitamin D level of only 13 ng/ml—a level considered to be severely deficient.[4] At least this group is following their own advice to avoid the sun. As you will see, not all dermatologists are following their own advice—especially those in the USA.

There are still other dermatologists who refuse to sing in the official choir of the Powers of Darkness. Writing in the British Medical Journal in 2008, Dr. Sam Shuster argued that the purported increase in melanoma is not really an increase at all, but an artifact due to non-melanoma lesions being diagnosed as melanoma.[5] In 2009, another study by dermatologists— Dr. Nick Levell and his colleagues, including Shuster—this time published by the British Journal of Dermatology, came to a similar conclusion and called the “increase” in melanoma a “midsummer night’s dream.”[6] They concluded, after tracking the reported increase in Melanoma in the Eastern region of the UK between 1991 and 2004, that benign lesions were being classified in increasing numbers as stage-one melanoma. No other stages of the disease increased, and the increase in mortality due to melanoma was either miniscule or non-existent. This was true even though all grades of tumors were diagnosed at first presentation. They also noted that “the distribution of the lesions reported did not correspond to the sites of lesions caused by solar exposure,”—in other words, the “cancers” were occurring on areas of the body seldom exposed to sunlight. Levell and his group also say that “the large increase in reported incidence is likely to be due to diagnostic drift which classifies benign lesions as stage 1 melanoma.”

They further stated that “These findings inevitably challenge the validity of epidemiology studies linking increasing melanoma incidence with UV radiation, and suggest the need for a search for other ways in which the disease may be caused.”

Dr. Ackerman agreed. In his meticulously documented monograph, he notes that “researchers have created an epidemic of melanoma when, in fact, the only change has been an “epidemic” in diagnoses of melanoma.”

Notwithstanding the research presented by these dermatologists, the American Academy of Dermatology (AADA) and other melanoma organizations continue to spread misinformation regarding the disease. Dr. William James, president of the AAD has said that melanoma has become the most common form of cancer for young adults 25-29 years old, testifying to that statement before the FDA.[7] Yet, he did not mention data from the National Cancer Institute indicating that death due to melanoma has decreased by 50% among women of ages 20-49 since 1975.[8] That means young women have less than one chance in 100,000 of dying from melanoma, which does not even place it in the top 15 causes of cancer death.[9] And, the American Cancer Society states that “since 2000 melanoma has been decreasing rapidly in whites younger than 50, by 3% per year in men since 1991 and by 2.3% per year since 1995 in women.” We might ask why these figures are not included in the statements by dermatologists regarding the “epidemic” of melanoma. Could it be because of a cozy financial relationship with pharmaceutical companies that produce sunscreen?[10]

Harmon Leon gave another reason to question the “epidemic” of melanoma: The USA has 4.5% of the world’s population, yet has 52% of the world’s melanoma. The American Cancer Society estimates 68,720 new melanomas in the US during 2009,[11] whereas the World Health Organization estimates 132,000 new cases yearly worldwide.[12] Something is very strange here. It certainly seems that the exceptionally high melanoma figures in the USA might be doctored to produce sunscreen sales, dermatology visits and the removal of benign leisions.

In addition, Dr. Ackerman points out the following in his monograph:

1. The American Academy of Dermatology (AAD), the Skin Cancer Foundation and the American Cancer Society sold their seals of recognition to manufacturers of sunscreens, based on research conducted solely by the sunscreen industry. The price, he says, was “substantial in terms of dollars but incalculable in terms of honor.” For instance, for an application of $10,000 and an annual fee of 5,000, sunscreen manufacturers may boast approval of their products in the form of the “Seal of Recognition” of the American Academy of Dermatology. They then display this seal on the front of their tubes. The American Cancer Society allows its logo to be placed on tubes of Neutrogena sunscreens in exchange for $300,000 annually.
2. In 2007, the year in which the Seal of Recognition program for the AAD was implemented, the past president of the board, who chaired the Seal program, and half the members of the board had financial ties to companies that manufacture sunscreen. And in 2008, all four new members of the board had those ties.
3. Darrell Rigel, a former president of the AAD, affirmed how important it was to avoid the sun while he, himself, was on vacation in Hawaii.
4. The AAD ran announcements for and updates on their scientific meetings, stating that they took place in “Sunny San Diego” and “Sunny San Antonio.” [Aren’t they supposed to avoid the sunlight?]

We now have two possibilities (see parts 1 and 2 of this post). (1.) Either melanoma has increased exponentially while sunlight exposure dramatically decreased or (2.) There has been no increase in melanoma; the purported increase is nothing more than an increase in the number of harmless skin spots that are being diagnosed as melanoma by an increasing number of dermatologists. In either case, the idea that regular, non-burning sunlight exposure is the cause of melanoma is a fraud—an idea promulgated by dermatological academies, sunscreen manufacturers and melanoma foundations driven by the desire for profit.

The Sunlight-avoidance insanity is causing severe vitamin D deficiency. Will you die from sunlight deprivation?

--
Due to fear of melanoma, a deadly disease that has been erroneously attributed to sunlight exposure, the people are leaving the sunlight and becoming more like cave dwellers. For those of you who believe in evolution, can you imagine that after millions of years under the sun, human beings have been frightened away from their heritage?

There is an inconvenient truth about melanoma that the Powers of Darkness (those who would take away our sunlight) would prefer you not know: people who work regularly outdoors have a lower risk of melanoma than those who work indoors.

Godar, et al.[1] present evidence that outdoor workers, while receiving 3-9 times the UVR exposure as indoor workers,[2] [3] have had no increase in melanoma since before 1940, whereas melanoma incidence in indoor workers has increased steadily and exponentially. Other research corroborates the idea that outdoor workers have fewer melanomas than indoor workers.[4] Vagero, et al.[5] showed that melanomas were more common among indoor office workers and other indoor workers than among outdoor workers, and Kennedy, et al.[6] showed that a lifetime of sunlight exposure correlated to a reduced risk of melanoma. Garland, et al.[7] showed that those who worked indoors had a 50% greater risk of melanoma than those who worked both indoors and outdoors, and Kaskel, et al.[8] demonstrated that children who engage in outdoor activities are less likely to develop melanoma than those who do not. Many other papers in the scientific literature show that both incidence and death rate from melanoma are reduced with increasing exposure to sunlight.[9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19]

This is not to say that sunburn does not contribute to melanoma, but it certainly shows that habitual, non-burning sun exposure correlates to a reduced risk of this deadly disease. In addition, there are approximately 105 additional diseases that are reduced among those who have higher sunlight exposure and therefore have higher levels of vitamin D (see my book for a discussion on each disease). We cannot live without vitamin D, which is not a vitamin at all, but in its most active form is a potent steroid hormone that controls at least 1,000 genes.[20] It is also important to understand that 90% of all vitamin D is produced in the skin by the action of sunlight on skin.[21]

However, blood levels of this important hormone are dropping precipitously in the American population, with a near doubling of the prevalence of vitamin D insufficiency that existed 10 years ago, and with 90% of Blacks, Hispanics and Asians, and 75% of the white population now suffering from the disorder.[22]

So what does this mean to the health of US citizens? I have calculated in a manuscript currently in preparation, that the diseases that correlate to sunlight deprivation/vitamin D deficiency kill approximately 1.42 million people per year in the US. Diseases that correlate to sunlight exposure kill approximately 1,500 people per year. That produces a ratio of about 948:1. I will continue with my mid-day sunbathing, thank you!

Remember that no one is advising the injudicious use of sunlight; baking in the sun for hours is neither necessary nor desirable, but regular sunlight exposure is a sine qua non for vibrant health. To say that we should avoid sunlight is like saying we should avoid water. Water correlates to drowning, but no one asks us to avoid water; if we did the results would be catastrophic, as are the results of vitamin D deficiency due to sunlight deprivation.

Of course, there are some extremely rare conditions that may preclude sunlight exposure. Check with your (enlightened) physician.

Is it time to return to reasonable, habitual, non-burning sunlight exposure? It could save your life!

Vitamin D deficiency and death from diarrhea—another reason to return to the sunlight

--
WebMD just posted an article regarding research on vitamin D levels and a particular “superbug,” clostridium difficile or C. diff, which causes severe diarrhea and death. http://www.webmd.com/digestive-disorders/news/20100505/c-diff-may-be-worse-with-low-vitamin-d

C. Diff occurs primarily in people who have been taking broad-spectrum antibiotics that kill the friendly bacteria that would keep this superbug under control.

The author noted that 53% of the patients with “normal” levels of vitamin D were able to resolve the infection and then remain free of diarrhea after 30 days. In those with “low” vitamin D levels, only 26% resolved the infection and remained free of diarrhea after 30 days.

The researchers defined low vitamin D levels as 21 ng/ml, which is very low indeed, since a level of 32 is considered the lowest level for good health, and most scientists now recommend levels of about 60 ng/ml as optimal. I’m assuming that “normal” levels were considered to be anything over 21 ng/ml.

Vitamin D has been known for some time to be a potent antibiotic which breaks down the cell walls of both bacteria and viruses. However, it is not a “broad-spectrum” antibiotic—an antibiotic that kills not only the disease-causing pathogens—but also the friendly bacteria in the intestine that work to keep such pathogens at bay. Vitamin D recognizes only the foreign invader (pathogen) that can damage the body. Unfortunately, many pathogens develop resistance to antibiotic drugs, and the drugs cannot then kill the pathogen, which has a heyday because it is unopposed by the friendly bacteria that would normally thwart its action; hence, we have the term “superbug.”

Vitamin D works by stimulating the immune system’s army of cells such as T cells[1] and macrophages[2] to attack and destroy pathogens. There is no research I am aware of indicating that any pathogen develops a resistance to vitamin D. As antibiotics become less and less effective in fighting pathogens, optimal levels of vitamin D may become our last line of defense.

The WebMD article also points out that “Overall, 40% of the patients died during the month." A total of 67% of patients with low vitamin D levels died compared with 44% of those with normal vitamin D levels…” This indicates that the levels considered normal were not normal at all, and probably came nowhere near the optimal levels of 60 ng/ml.

And who is responsible for this loss of life? It is obviously the Powers of Darkness, those organizations that profit from teaching us that we should “protect” ourselves from any contact with sunlight or other sources of natural vitamin D production such as sun lamps. It behooves us to return to the habit of regular, non-burning sunlight exposure, such as sunbathing, preferably around midday. That certainly seems like a terrific alternative to death by diarrhea. Would you agree?

Rheumatoid arthritis, sunlight deprivation and vitamin D—so what’s new?

--
An interesting study on rheumatoid arthritis (RA) and latitude appeared recently in the online journal, Environmental Health Perspectives.[1] The researchers found that the disease was considerably more prevalent among those living at higher latitudes than at lower latitudes. They had expected to find a relationship between air pollution and RA, but such a relationship did not exist. They concluded that the correlation of high latitudes to RA was probably due to less vitamin-D producing sunlight exposure and consequent vitamin D deficiency. My response is, “This is news?”

There should have been so expression of surprise about the results. RA is one of many autoimmune diseases, and it has long been known that vitamin D has a profound, positive influence on those diseases.[2] These are diseases in which the immune system attacks the body’s own healthy tissue, mistaking that tissue for a foreign invader. When this happens, a specialized immune-system cell (called a T cell) assaults and kills some of the tissue of a targeted organ. Autoimmune diseases, then, are caused by T cells gone awry. In the case of rheumatoid arthritis the immune system attacks the collagen-producing cells of the joints. T cells in a person with an autoimmune disease lack the “intelligence” to recognize that they are attacking the wrong tissue. That intelligence, in part, comes from vitamin D, the receptors of which are found in large quantities in mature T cells and even larger concentrations in immature T cells produced in the thymus gland. Without vitamin D stimulation of the receptor sites, these cells will not function properly. When vitamin D is present however, they have the ability to discern between foreign invaders and the body’s own tissue. Animal experiments show that vitamin D acts as a “selective immunosuppressant” (see footnote 2), meaning that it gives T cells the ability to distinguish between “good and evil.” It is this ability to reduce the autoimmune response, as well as its anti-inflammatory properties that are likely responsible for the lessened risk of RA in sun-deprived areas, and this is further corroborated by the fact that RA is also more severe in winter,[3] a time of less sunshine, and a time when sunlight exposure in northern latitudes does not produce vitamin D.

In another report from researchers in Ireland (a northern country with little sunlight exposure), it was shown that 70% of patients had low vitamin D levels and that 26% were severely deficient.[4] However, in that report, 21 ng/ml was considered as the deficiency level and 10 ng/ml as the severe deficiency level. In reality, a level of 21 is dangerously deficient. It is likely that all of these patients had levels under 32 ng/ml, now considered the lowest level for good health. My opinion is that levels of 50 to 60 are optimal.

Considering this information, it should have come as no surprise that RA was more common at higher latitudes. It is time to return to the sun in the summer and to find ways of maintaining optimal vitamin D levels in the winter through the use of sun lamps.
