The Surprising Cause of Melanoma (And No, It’s Not Too Much Sun)

Rates of melanoma, the deadliest form of skin cancer, have been rising for at least the last three decades, and this increase has been largely blamed on exposure to ultraviolet (UV) light from the sun.

However, research published in the British Journal of Dermatology shows that the sun is likely nothing more than a scapegoat in the development of melanoma, and the sharp increase may actually be “an artifact caused by diagnostic drift.”

Melanoma Increases Due to Benign Disease, Not Sunlight

Diagnostic drift, according to the study, refers to a hefty increase in disease that is being fueled by non-cancerous lesions.

In fact, during the study period from 1991 to 2004, there were nearly 4,000 cases of melanoma included in the report, with an annual increase of 9.39 to 13.91 cases per 100,000 per year.

The researchers revealed that, rather than being fueled by increasing exposure to sunlight as is commonly suggested, the increased incidence was almost entirely due to minimal, stage 1 disease.

They noted:

“There was no change in the combined incidence of the other stages of the disease, and the overall mortality only increased from 2.16 to 2.54 cases per 100,000 per year … We therefore conclude that the large increase in reported incidence is likely to be due to diagnostic drift, which classifies benign lesions as stage 1 melanoma.”

In other words, people are being diagnosed with melanoma skin cancer even when they have only a minimal, non-cancerous lesion, and these diagnoses appear to be skewing disease rates significantly. Further, adding even more credence to the growing body of evidence showing sun exposure is not the primary cause of melanoma, the researchers noted that the distribution of the lesions reported did not correspond to the sites of lesions caused by sun exposure.

They concluded:

“These findings should lead to a reconsideration of the treatment of ‘early’ lesions, a search for better diagnostic methods to distinguish them from truly malignant melanomas, re-evaluation of the role of ultraviolet radiation and recommendations for protection from it, as well as the need for a new direction in the search for the cause of melanoma.”

Is Lack of Sunlight a More Likely Culprit?

Despite all the bad press linking sun exposure to skin cancer, there’s almost no evidence at all to support it. There is, however, plenty of evidence to the contrary. Over the years, several studies have confirmed that appropriate sun exposure actually helps prevent skin cancer. In fact, melanoma occurrence has been found to decrease with greater sun exposure, and can be increased by sunscreens.

One of the most important facts you should know is that an epidemic of the disease has in fact broken out among indoor workers. These workers get three to nine times LESS solar UV exposure than outdoor workers get, yet only indoor workers have increasing rates of melanoma — and the rates have been increasing since before 1940.

There are two major factors that help explain this, and the first has to do with the type of UV exposure.

There are two primary types of UV rays from sunlight, the vitamin-D-producing UVB rays and the skin-damaging UVA light. Both UVA and UVB can cause tanning and burning, although UVB does so far more rapidly. UVA, however, penetrates your skin more deeply than UVB, and may be a much more important factor in photoaging, wrinkles and skin cancers.

A study in Medical Hypotheses suggested that indoor workers may have increased rates of melanoma because they’re exposed to sunlight through windows, and only UVA light, unlike UVB, can pass through window glass. At the same time, these indoor workers are missing out on exposure to the beneficial UVB rays, and have lower levels of vitamin D.

Researchers wrote:

“We hypothesize that one factor involves indoor exposures to UVA (321–400nm) passing through windows, which can cause mutations and can break down vitamin D3 formed after outdoor UVB (290–320nm) exposure, and the other factor involves low levels of cutaneous vitamin D3.

After vitamin D3 forms, melanoma cells can convert it to the hormone, 1,25-dihydroxyvitamin D3, or calcitriol, which causes growth inhibition and apoptotic cell death in vitro and in vivo.

… We agree that intense, intermittent outdoor UV overexposures and sunburns initiate CMM [cutaneous malignant melanoma]; we now propose that increased UVA exposures and inadequately maintained cutaneous levels of vitamin D3 promotes CMM.”

To put it simply, UVB appears to be protective against melanoma — or rather, the vitamin D your body produces in response to UVB radiation is protective.

As written in The Lancet:

“Paradoxically, outdoor workers have a decreased risk of melanoma compared with indoor workers, suggesting that chronic sunlight exposure can have a protective effect.”

Vitamin D Helps Protect You Against Cancer

Vitamin D is a steroid hormone that influences virtually every cell in your body, and is easily one of nature’s most potent cancer fighters. So I want to stress again that if you are shunning all sun exposure, you are missing out on this natural cancer protection.

Your organs can convert the vitamin D in your bloodstream into calcitriol, which is the hormonal or activated version of vitamin D. Your organs then use it to repair damage, including damage from cancer cells and tumors. Vitamin D’s protective effect against cancer works in multiple ways, including:

  • Increasing the self-destruction of mutated cells (which, if allowed to replicate, could lead to cancer)
  • Reducing the spread and reproduction of cancer cells
  • Causing cells to become differentiated (cancer cells often lack differentiation)
  • Reducing the growth of new blood vessels from pre-existing ones, which is a step in the transition of dormant tumors turning cancerous

This applies not only to skin cancer but other types of cancer as well. Theories linking vitamin D to certain cancers have been tested and confirmed in more than 200 epidemiological studies, and understanding of its physiological basis stems from more than 2,500 laboratory studies, according to epidemiologist Cedric Garland, DrPH, professor of family and preventive medicine at the UC San Diego School of Medicine.

Here are just a few highlights into some of the most noteworthy findings:

  • Some 600,000 cases of breast and colorectal cancers could be prevented each year if vitamin D levels among populations worldwide were increased, according to previous research by Dr. Garland and colleagues.
  • Optimizing your vitamin D levels could help you to prevent at least 16 different types of cancer including pancreatic, lung, ovarian, prostate, and skin cancers.
  • A large-scale, randomized, placebo-controlled study on vitamin D and cancer showed that vitamin D can cut overall cancer risk by as much as 60 percent. This was such groundbreaking news that the Canadian Cancer Society has actually begun endorsing the vitamin as a cancer-prevention therapy.
  • Light-skinned women who had high amounts of long-term sun exposure had half the risk of developing advanced breast cancer (cancer that spreads beyond your breast) as women with lower amounts of regular sun exposure, according to a study in the American Journal of Epidemiology.
  • A study by Dr. William Grant, Ph.D., internationally recognized research scientist and vitamin D expert, found that about 30 percent of cancer deaths — which amounts to 2 million worldwide and 200,000 in the United States — could be prevented each year with higher levels of vitamin D.

When Using the Sun to Fight Cancer, the Dose is What Matters

When I recommend using the sun therapeutically, this means getting the proper dosage to optimize your vitamin D levels. This typically means exposing enough of your unclothed skin surface to get a slight pink color on your skin. Your exact time will vary radically depending on many variables, such as you skin color, time of day, season, clouds, altitude and age.  The key principle is to never get burned, while still spending as much time as you can in the sun during the peak hours, as it is virtually impossible to overdose as long as you don’t get burned.

A common myth is that occasional exposure of your face and hands to sunlight is “sufficient” for vitamin D nutrition. For most of us, this is an absolutely inadequate exposure to move vitamin D levels to the healthy range. Further, if you use sunscreen, you will block your body’s ability to produce vitamin D!

And, contrary to popular belief, the best time to be in the sun for vitamin D production is actually as near to solar noon as possible which is 1 PM in the summer for most (due to Daylight Saving Time).. The more damaging UVA rays are quite constant during ALL hours of daylight, throughout the entire year — unlike UVB, which are low in morning and evening and high at midday.

When using the sun to maximize your vitamin D production and minimize your risk of malignant melanoma, the middle of the day (roughly between 10:00 a.m. and 1:00 p.m.) is the best and safest time. During this time you need the shortest exposure time to produce vitamin D because UVB rays are most intense at this time. Plus, when the sun goes down toward the horizon, the UVB is filtered out much more than the dangerous UVA.

Once you reach this point your body will  peak at about 10,000-40,000 units of vitamin D. Any additional exposure will only cause harm and damage to your skin. Most people with fair skin will max out their vitamin D production in just 10-20 minutes, or, again, when your skin starts turning the lightest shade of pink. Some will need less, others more. The darker your skin, the longer exposure you will need to optimize your vitamin D production.

Why Not Just Take Vitamin D from a Supplement?

ou can get vitamin D3 in supplement form, and if sunlight or a safe tanning bed is not an option, this is a better choice than getting no vitamin D at all. If you do use a supplement, it now appears as though most adults need about 8,000 IU’s of vitamin D a day in order to get their serum levels above 40 ng/ml.

However, sunlight is really the superior source for vitamin D, as when you expose your skin to sunshine, 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 bloodstream, whereas the unsulfated form needs LDL (the so-called “bad” cholesterol) as a vehicle of transport.

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 your vitamin D requirements from exposure to sunshine, or by using a safe tanning bed (one with electronic ballasts rather than magnetic ballasts, to avoid unnecessary exposure to EMF fields). Safe tanning beds also have less of the dangerous UVA than sunlight, while unsafe ones have more UVA than sunlight. If neither of these are feasible options, then you should take an oral vitamin D3 supplement.

What Should Your Vitamin D Levels be for Cancer Protection?

In 2007 the recommended level was between 40 to 60 nanograms per milliliter (ng/ml). Since then, the optimal vitamin D level has been raised to 50-70 ng/ml, and when treating cancer or heart disease, as high as 70-100 ng/ml.

I recommend you have your levels tested and regularly monitored to make sure they are in the therapeutic range. Your physician can do this for you, or another alternative is to join the DAction study. DAction is a worldwide public health campaign aiming to solve the vitamin D deficiency epidemic through focus on testing, education, and grassroots word of mouth.

When you join D*action, 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 $60 fee each 6 months ($120/year) for your sponsorship of the project, which includes a complete new test kit to be used at home, and electronic reports on your ongoing progress.

Natural Treatment for Non-Melanoma Skin Cancer

Melanoma skin cancer is the deadliest form, but far more common are non-melanoma skin cancers, which impact millions of Americans every year.

If you or someone you love is affected, a cream containing eggplant extract, known as BEC and BEC5, appears to cure and eliminate most non-melanoma skin cancers in several weeks time. Unlike conventional skin-cancer treatment, which is often surgery, the eggplant-extract cream leaves no scarring and no visible sign a tumor or lesion was ever present. The eggplant extract appears to be exceptionally safe and only kills cancerous cells, leaving healthy cells untouched, and causes only minor side effects, such as itching and burning.

The leading researcher in this area today is Dr. Bill E. Cham, who reported as early as 1991 in Cancer Letters that:

A cream formulation containing high concentrations (10 percent) of a standard mixture of solasodine glycosides (BEC) has been shown to be effective in the treatment of malignant and benign human skin tumors.

We now report that a preparation … which contains very low concentrations of BEC (0.005 percent) is effective in the treatment of keratoses, basal cell carcinomas (BCCs) and squamous cell carcinomas (SCCs) of the skin of humans. In an open study, clinical and histological observations indicated that all lesions (56 keratoses, 39 BCCs and 29 SCCs) treated with [the preparation] had regressed.”

Dr. Cham’s latest study was published in the International Journal of Clinical Medicine this year. The paper includes two impressive case reports of 60-something men who were suffering from large basal cell carcinoma (BCC) or squamous cell carcinoma (SCC), which had plagued them for years.  The results upon treatment with a cream formulation of BEC (eggplant extract) twice a day are astounding, and you can view the pictures here.

Unfortunately, simply eating eggplant, tomatoes, peppers or similar veggies, while beneficial for many reasons, will not induce this same effect because the active components are not able to effectively penetrate your cells. This requires the addition of glycosides, molecules with various simple sugars attached to them that can latch on to receptors found on skin cancer cells.

Simple Skin Cancer Prevention Strategies

What’s even better than an inexpensive, safe and natural cure for skin cancer is, of course, preventing it in the first place. Your body is made to be in the sun, and, when done properly, sun exposure will be one of the best ways you can help reduce your risk of skin, and many other forms of, cancer.

Along with optimizing your vitamin D levels, the carotenoid astaxanthin has also piqued the interest of researchers due to its ability to reduce signs of aging by helping protect your skin from sun damage. I personally take 8 mg every day to help limit any potential damage from sun exposure as most of the year I am able to spend one to two hours a day in the sun.

Consuming a healthy diet full of natural antioxidants is another useful strategy to avoid sun damage to your skin, as fresh, raw, unprocessed foods deliver the nutrients that your body needs to maintain a healthy balance of omega-6 and omega-3 oils in your skin, which is your first line of defense against sunburn.

Fresh, raw vegetables also provide your body with an abundance of powerful antioxidants that will help you fight the free radicals caused by sun damage that can lead to burns and cancer.

    Skin cancer can be removd with apple cider vinegar by action of its acid.
    I used cotton ball with tape, soaked part of cotton ball in apple cide vinegar, taped it to basal cell cancer, leave it there for 20 minutes, you will feel slight burning on skin. Repeat again next day for 20 minutes. Soon skin area will turn black like it was burned. Apply aloe vera for 2-3 days then black skin will fall off and fresh new skin will remain. If skin cancer is still there, repeat until all skin layers with cancer have been removed. It only took me 4-5 days to remove the cancer.

    “The Surprising Cause of Melanoma (And No, It’s Not Too Much Sun)”

    No, that’s not what the study says. It says that the increase in diagnoses in later years is, in their view, not entirely due to melanoma cases, but includes other afflictions. IT DOES NOT SAY THAT MELANOMA CASES AREN’T CAUSED BY SUN EXPOSURE. That is something the four researchers do not question, as it is well documented.

    Almost 10 years ago I was diagnosed with a severs case of melanoma and the doctors recommended surgery, removing lymph glands, radiation and chemo. I refused and told them to their shock that God and the natural products He put on earth would fix my cancer. I used Black Salve and herbs as well as a Rife machine. I juiced and changed my diet and today I am healthy with no more cancer. Thank God!

    UVB is the shorter wavelength that burns surface skin not UVA. Please clarify and correct if I have misunderstood.

    Per Mercola, 20 minutes of cloudless sun each side, noon to one pm. The sun must be above 50 degrees, and noon in Phoenix is at 80 degrees, burning today.
