Let’s revisit the need for appropriate nutrition in preventing melanoma death.

By Marc Sorenson, EdD, Sunlight Institute

Let’s revisit the need for appropriate nutrition in preventing melanoma death.

It has been well-established that melanoma is not caused by sunlight exposure, despite the sunphobes’ protestations to the contrary. There are numerous research papers that indicate melanoma is considerably less frequent among those who are regularly exposed to sunlight than among those who avoid it.[1] [2] [3] [4] [5] (The references cited here are only a few of the many papers that corroborate the fact that melanoma is less common among those who embrace the sun.)

Sunlight Reduces the Risk of Death!

By: Marc Sorenson, EdD Sunlight Institute–

More than two years ago I read of ongoing research by Dr. Pelle Lindqvist—reasearch indicating that greater exposure to sunlight resulted in longer life. I made several attempts to contact Dr. Lindqvist, but was unsuccessful. However, one of his colleagues answered my query and informed me that the research would not be completed later on and then be published. The results are now available, and they are impressive.[1]

During a 20-year period, the subjects in the study who avoided sun exposure were twice as likely to die of any cause compared to those who had the highest sun exposure, and the researchers made this statement: “In both models the summary sun exposure variables showed a ‘dose-dependent’ inverse relation between sun exposure and all-cause death.”

Regular Occupational Sunlight Exposure is Associated with a Reduced risk of Melanoma on the Face and Arms.

By: Marc Sorenson, Sunlight Institute–

From University of Sydney in Australia comes the latest research to contradict one of the biggest lies of the past several decades: that melanoma is caused by sunlight exposure.

The results of the investigation were recently published in the International Journal of Cancer, and demonstrated that regular sunlight exposure was not associated with either overall melanoma risk or risk at different body sites.[1] To the contrary, the highest sunlight exposure predicted a 44% decreased risk of melanoma on the head and neck when compared to the lowest exposure.

In addition, when sunlight exposure to the upper limbs was assessed, the highest exposure was associated with a decreased risk of melanoma of 34%. The authors stated, “Our results suggest that occupational sun exposure does not increase risk of melanoma, even of melanomas situated on the head and neck.”

Stated another way, the authors might have suggested that sunlight exposure protects against the risk of contracting melanoma. In reading this research, I was reminded of a statement by Dr. Frank Garland during his presentation at a vitamin D conference I attended several years ago. He said, “melanoma is a disease of sedentary, indoor office workers.” He was absolutely correct.

Those who have bought the propaganda of the American Academy of Dermatology may consider this information quite surprising, but in reality it is just one more in a long line of scientific investigations pointing out several reasons that melanoma is not caused by sunlight exposure: (1) Most melanomas occur on areas of the body that are seldom exposed to sunlight. (2) As sunscreen use has increased, melanoma has also increased. (3) Outdoor workers have far less risk of melanoma than indoor workers. (4) As the populace has left outdoor work and moved indoors, profoundly reducing sunlight exposure, melanoma has increased exponentially.

For those interested in reading further regarding these statements and also searching the references, they are contained on previous posts on this site. In the meantime, let’s take advantage of some non-burning sun exposure to protect ourselves against melanoma.

I’m grateful to the scientists from Australia who brought forth this information. Truth will ultimately prevail.

Alcohol and Melanoma: More Proof that this Deadly Skin Cancer is not caused by Sunlight

By: Marc Sorenson, Sunlight Institute–

Those who make a fortune by maligning the sunlight as the cause of melanoma, fail to consider that there are many factors that correlate to an increased melanoma risk. Two decades ago, an important study was published in the Annals of Epidemiology, which pointed to several nutritional factors, one of which was the consumption of alcohol.[1] In that research, women who drank two or more drinks per day had an increased risk of melanoma of 250%. Then, in 2004, Amy Millen and her colleagues showed that  high alcohol consumption (2.8 drinks per week) correlated to an increased risk of melanoma of 69%.[2]

When considering those studies, it becomes obvious that increasing consumption of alcohol leads to increasing risk of melanoma. Millen’s research, by the way, defined many other nutritional factors that lead to either an increased risk of melanoma or a protection against the disease. I discussed those factors in an earlier post on nutrition and melanoma. http://sunlightinstitute.org/skin-cancer-and-nutrition%E2%80%94stop-blaming-sun

The latest research corroborates the findings of the two aforementioned studies. Jessica Kubo and colleagues investigated the effect of alcohol consumption on the risk of melanoma in a 10.2-year study.[3] Several interesting observations emerged: (1) those who consumed 7+ drinks per week had a 64% increased risk of melanoma; (2) higher lifetime alcohol consumption was positively correlated to risk of the disease; (3) higher current alcohol consumption similarly correlated to a higher risk: (4) current alcohol intake also predicted higher risk; (5) a preference for white wine or liquor also predicted increased risk.

So you see, the idea that melanoma is caused by sunlight exposure is again refuted. We know that as sunlight exposure has decreased profoundly in the last 100 years, the risk of melanoma has increased exponentially. When sunlight exposure has decreased and melanoma has concomitantly increased, what more needs to be said? I have previously posted two blogs on this subject and believe that they entirely refute the claim that melanoma is caused by sunlight.http://sunlightinstitute.org/exposing-sunlightmelanoma-fraud-part-1   http://sunlightinstitute.org/exposing-sunlightmelanoma-fraud-part-2

It is time that we started using our heads and look for the real reason for melanoma. Alcohol is just one reason among many, and it is time to look to other deleterious lifestyles as being the real causes of this deadly disease.

Regular Sunny Holidays Predict Better Prognosis in Melanoma Patients.

By: Marc Sorenson, Sunlight Institute–

To those of us who support regular sun exposure, a study of epochal importance has just been published in the medical journal PLoS One. The lead author, Dr. Sara Gandini, has also performed previous research showing the efficacy of sunlight in enhancing health, and has brought to light that many factors not related to sunlight are the real causes of melanoma.[1]

In her latest publication, she and her colleagues show that holidays in sunny areas were significantly correlated to thinner melanomas,[2] meaning that the cancers were less likely to progress and spread. There was a dose-response protection against thicker melanomas; in other words, the greater the number of weeks of sunny holidays, the greater less the risk of thicker melanomas. This correlation existed only for women. The good news, however, is that for both sexes,recurrence of excised melanomas was reduced an average of 70% in those who spent the greatest number of days in the sunlight.

I and many others have said for years that not only does sunlight not cause melanoma, regular non-burning sunlight is protective against contracting melanoma. This new research corroborates that fact.

A similar study on melanoma thickness and the risk of relapse was done in 2009 by Julia Newton-Bishop and colleagues.[3] In that research, it was shown that subjects with higher vitamin D levels had thinner melanomas and a greater survival prognosis. Nevertheless, the results were not nearly as impressive as the study by Gandini, et al. Sunlight exposure per se appears to be superior to vitamin D levels per se in protecting against melanoma.

Sunlight exposure is the best and most natural way to produce large quantities of vitamin D in the human body, and we are learning that sunlight produces many health benefits beyond vitamin D production. This present research is another step forward in bringing sunlight back to its rightful position as mankind’s best friend.

The Indian Press says, “Bring on the Sunshine.”

By: MarcSorenson, Sunlight Institute–

In so many countries, sunlight is looked on with fear, and the press is constantly promoting that fear by warning that sun exposure in causing melanoma—an idea that is patently false.

Fortunately, in India not everyone is buying the sunscare propaganda. It is not uncommon to see articles in the Indian press expressing the concern that Indians, many of who have adopted the indoor lifestyles of western countries, are becoming severely deficient in vitamin D due to lack of sunlight exposure. One of those articles was recently published in the online version of India Today. The author, Nalini Ravichandran, correctly points out: “Scientific studies have proven that Vitamin D is like the ignition key to your car; the car won’t run unless you turn the key and ignite the engine. So get started in the right direction, before it gets too late.” In other words, seek the sunlight!

The author also laments the fact that 80% of Indians are now vitamin-D deficient. The only thing lacking in this excellent piece is a discussion of all the benefits of sunlight beyond vitamin D.

I applaud the efforts of the Indian press to bring the truth about sunlight to their populace. I have seen several articles in the past year all extolling the benefits of sunlight. Now, if only we could get the western press to catch up!

Redheads are more prone to melanoma regardless of sunlight exposure

By: Marc Sorenson, EdD Sunlight Institute–


I have often stated that melanoma is more common in people with type-1 (non-tanning, pale) skin, and that moles correlate to a higher risk of skin cancer regardless of sunlight exposure. Now, new research shows that the genetic makeup that accompanies red hair–not the amount of sun exposure–also correlates to an increased risk of melanoma. Read the article.

So what does this mean? Let’s stop attacking the sun and start addressing the real causes of skin cancers: 1. the presence of many moles on the skin[i], 2. Underexposure to sunlight[ii], 3. Lack of colorful fruits and vegetables in the diet[iii], 4. Drinking alcohol[iv], 5. Consumption of dairy products[v] and 6. Environmental pollutants such as PCBs.[vi] (see below for references). And of course, we have just established red hair as a risk factor for melanoma.

Exposure to sunlight has decreased dramatically in the last century, and sunscreen sales have exploded. During that same time there has been a concomitant exponential increase in melanoma. How then, can anyone in their right mind say that sunlight exposure causes melanoma? GET SERIOUS! The idea that sunlight causes melanoma, of course, is great way to sell sunscreens. Follow the money and you will discover the reasons for the promulgation of the sunlight/melanoma nonsense. Non-burning sunlight is our greatest friend and health enhancer. Check with your doctor before you make any changes in lifestyle.

Another recommendation to get plenty of sunshine–to PREVENT melanoma!

By: Marc Sorenson, Sunlight Institute–

In this excellent article, Dr. Charles  Reinert tells about how his mother  contracted melanoma on her chest (an area where she seldom was exposed to sunlight) and died of the disease shortly thereafter. He makes the point, as I have done repeatedly, that regular sunlight exposure is associated with a decreased risk of melanoma. He also lists several additional diseases that increase with decreased sunlight exposure. An excellent read.
