Skin Cancer

July 13, 2011

Skin CancerSkin cancer is the growth of abnormal cells capable of invading and destroying other associated skin cells. Skin cancer is often subdivided into either melanoma or non-melanoma. Melanoma is a dark-pigmented, usually malignant tumor arising from a skin cell capable of making the pigment melanin (a melanocyte). Non-melanoma skin cancer most often originates from the external skin surface as a squamous cell carcinoma or a basal cell carcinoma.

Because these types of cancer act so differently, they also need different treatments–the melanoma type more directed at stopping the metastasis, the non-melanoma types aimed at stopping the localized growth. While non-melanoma skin cancers have been more conclusively associated with trauma to the skin, usually in the form of sunburns, melanomas may not have any relationship at all to sun exposure, although this is controversial in the dermatology world.1

What are the Symptoms of Skin Cancer?

  • A red lump (spot or mole) that is firm
  • A sore or spot that bleeds or become crusty. Also look for sores that don’t heal
  • Rough and scaly patches on the skin
  • Any new growth that is suspicious
  • small lump (spot or mole) that is shiny, waxy, pale in color, and smooth in texture
  • Flat scaly areas of the skin that are red or brown
  • Any change in size, shape or color of a mole or skin growth

What are the Causes of Skin Cancer?

In 2002, 50 percent– approximately 1.1 million cases–of all cancers in the United States were skin cancers, of which nearly 10,000 cases were fatal. It is understandable why many people have become fearful of the sun.

In fact, the food you ingest is far more of a culprit in the development of skin cancers than sun exposure. In the last 100 years the U.S. population has gone from consuming virtually no vegetable fats to consuming more than 70 pounds per year. Fats from corn oil, safflower, sunflower, sesame and other oils are virtually 100 percent omega-6 fats. This high consumption of omega-6 fats completely alters the important omega 6:3 ratio, and this ratio is one of the keys to obtaining any type of cancer, skin cancer in particular. 2

Diet and Lifestyle

Keeping your diet clean and simple is your best bet in skin cancer prevention or recovery from skin cancer.  Do not consume artificial sweeteners or MSG. Drastically reduce or eliminate alcohol, caffeine and refined sugar. Eat lots of organic fruits and vegetables, make sure your meat and dairy is pasture-raised (full of Omega 3s) and your fish wild-caught. Good fats include organic virgin coconut oil, virgin olive oil, avocados, and organic nuts.

You will greatly benefit from consuming additional omega-3 fats, but it is vital to reduce the omega-6 vegetable oils as much as possible. Ideally, the ratio should be 1:1, but most Americans have a 15:1 ratio (omega-6 to omega-3). The Japanese are the longest-lived culture on earth, and their ratio is about 3:1.3

According to a top cancer journal, epidemiological, experimental, and mechanistic data implicate omega-6 fat as stimulators and long-chain omega-3 fats as inhibitors of development and progression of a range of human cancers, including melanoma.4

Over a decade ago, an Australian study showed a 40 percent reduction in melanoma for those who were eating fish–and this was without any attention to lowering omega-6 fats. Recently, the National Academy of Sciences published a comprehensive review showing that the omega 6:3 ratio was the key to preventing skin cancer development.

Beware of most sunscreens

According to Natasha Campbell-McBride, MD: “Skin cancer, blamed on sunshine, is not caused by the sun. It is caused by trans fats from vegetable oils and margarine and other toxins stored in the skin. In addition, some of the sunscreens that people use contain chemicals that have been proven to cause skin cancer.” Most chemical sunscreens contain from 2 to 5 percent of benzophenone or its derivatives (oxybenzone, benzophenone- 3) as their active ingredient. Benzophenone is a powerful free radical promoter, used in industrial processes to initiate chemical reactions and promote cross-linking. Benzophenone is activated by ultraviolet light to produce free radicals, known to cause cancer.5  The greatest rise in melanoma has been experienced in countries where chemical sunscreens are heavily promoted.

As for the generally non-malignant type of skin lesions referred to as basal cell and squamus cell carcinomas, these we know are associated with exposure to sunlight, but there are other factors involved. These lesions occur when “DNA repair of ultraviolet light damage is compromised. Trans fats are a likely dietary factor that would impair DNA repair of ultraviolet light damage. Once trans fats are built into the cell membranes of the skin, many reactions cannot take place, including those involved in DNA repair.

Some of the chemicals have been implicated as causing thyroid problems. German researchers found that rats exposed to the sunscreen chemical 4MBC had raised levels of thyroid stimulating hormones and heavier thyroid glands. Another chemical, benzophenone 2, was found to alter thyroid hormone levels, although the effect was reversed by other chemicals present in sunscreens (BBC News, June 10, 2006).

In most situations, normal exposure to the sun is beneficial, not harmful, especially if you take care to avoid polyunsaturated oils and trans fats. If you are fair-skinned and are going to be in the sun for a long period of time, be sure to cover your upper body with a shirt, wear a large-brimmed hat and use a safe sunscreen.

Recommended Diet and Supplementation

1.Virgin Cod Liver Oil or Wild Salmon Oil

If you are not able to consume enough fish, then fish oil is an excellent way to hit your omega-3 fatty acid targets. Wild salmon oil is rich in vitamin A and D to help protect from a UV-induced sunburn and cancerous changes in DNA. What makes it unique to any other fish oil is that it contains astaxanthin, which is a carotenoid that acts as a natural sunblock for marine plants. Research shows that astaxanthin prevents cancer initiation by protecting DNA from ultraviolet and oxidant damage, reduces liver fat and triglycerides, reduces the impact of glycation, and keeps skin young. These two wild salmon oil products are the best ones available.

Cod liver oil is a superior source of vitamin A and D to protect the skin against aging and cancer, as well as anti-inflammatory omega-3 fatty acids that everyone needs to balance the omega-6 intake. There is a balance of making sure you are not getting too much sun, but also getting enough for vitamin D production. Cod liver oil provides a daily source of vitamin D through the seasons (especially in northern climates) without overexposure to sun damage. These two cod liver oil products are the most superior forms of cod liver oil, preserving the viking era methods.

2. Cordyceps

Medicinal mushrooms including cordyceps, wild chaga, oyster, reishi, shiitake and maitake have well documented properties that are anti-viral, antimicrobial, anti-cancer, anti-hyperglycemic, anti-inflammatory and cardioprotective. Cordyceps in particular has a wealth of research. According to WebMD, “Cordyceps might improve immunity by stimulating cells and specific chemicals in the immune system. It may also have activity against cancer cells and may shrink tumor size, particularly with lung or skin cancers.”

3. Vitamin C with Flavonoids

Vitamin C is a well known antioxidant capable of recycling vitamin E, both of which work together for the integrity of inside and outside every cell. A recent 2014 study found that vitamin C protected against UV irradiation-induced apoptosis by re-activating tumor suppression genes in skin cells. Higher doses of vitamin C is needed for most who do not have access to freshly picked vitamin C rich food.

4. Berries and Pomegranates

Many berries contain strong antioxidant qualities and the phytochemical ellagic acid – highest in wild berries, raspberries, strawberries and pomegranates – with several studies showing it can inhibit the growth of tumors of the skin, esophagus and lung.

You can also use a cold processed raw blend of 8 wild berries from the Canadian mountains called Berrimax. I have found using this with the raw wild greens concentrate really makes your skin noticeably glow. This isn’t surprising if you have seen wild berries and greens in the wild, which seems to be impossibly bright and healthy. Given the price of berries for what seems like one serving, this gives you daily dose of all the amazing compounds.

5. Dark Green Vegetables

High in folate, lutein and zeaxanthin, leafy greens can help protect your cells from the damaging effects of free radicals, caused from sun-induced inflammation and extended sun exposure. An association of green leafy vegetables with decreased risk of skin cancer has also been reported, and a higher consumption of fruits and vegetables was related to decreased risk of SCC risk by 54%.The more sun exposure you have, the higher your folate requirements. These amounts may be even higher with certain gene variants in MTHFR. Eat with a fat source like avocado or olive oil for optimal absorption.

Here is the wild geens blend called GreensFlush. I think both Berrimax and GreensFlush have gone under the radar. This one contains raw wild dandelion greens, burdock leaf and nettles, blended for detoxification, and therefore healthier skin. Dandelion greens alone are high in vitamin K, zeaxanthin, carotene, lutein, vitamin C, B6, riboflavin and many other trace minerals.

6. Tomatoes and Watermelon

Rich in lycopene, a bright red carotenoid that has been shown to protect our skin from harmful UV damage, watermelons and tomatoes can help reduce the risk for skin cancer. One study found that lycopene was photoprotective, and inhibit proliferation of several types of cancer cells. Watermelons have 40 percent more lycopene than tomatoes, and this water-rich fruit can help protect you from sunburns and sun damage. Isn’t it remarkable how nature provides these during the summer? Eat both with a fat source of optimal absorption. Feta goes well with sliced watermelon, and olive oil with tomatoes. Other small amounts are found in calendula, pink grapefruit, guava, papayas and apricots.

7. Lime, Lemon and Orange Zest, Green Tea and Black Tea

Citrus foods contain limonene, which is highly concentrated in the rind. A study found the presence of limonene in the body can reduce the risk of squamous cell carcinoma. Green and black tea’s potent antioxidants protect your DNA from damage caused by light/sun exposure. Green and black tea is also used to make Kombucha.

8. Raw Cacao

Good news chocolate lovers! Chocolate has become recognized as an antioxidant-rich food that can help shield the skin against sun damage. One study found that dietary flavanols from cocoa contribute to endogenous photoprotection, improves dermal blood flow, hydration and complexion.
