Preventing Cancer Joseph Mercola

What Could Possibly Stop or Reverse This Troubling Trend?
If we begin with the rising incidence of skin cancer, a common presumption is that melanoma is caused by sun exposure. However, there's almost no evidence at all to support that stance. 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, while melanoma rates seem to rise with sunscreen use!

One such study discovered that melanoma patients that had higher levels of sun exposure were less likely to die than other melanoma patients, and patients who already had melanoma and got a lot of sun exposure were prone to a less aggressive tumor type.

In addition, melanoma strikes indoor workers more frequently than outdoor workers to begin with. It is also more common on regions of your body that are not exposed to the sun at all, so clearly the simplistic "sun equals cancer" theory is fundamentally flawed.

The missing piece of information that can explain this puzzle is the fact that melanoma rates are rising as sun exposure and vitamin D status is decreasing dramatically.

Although the sun does increase genetic damage in your skin, and can cause skin cancer, your body has a cleverly designed system to avert cancer growth. But when you avoid sun exposure entirely, you also circumvent your body's built-in system that helps prevent skin cancer naturally, because the key to unlock this mechanism is vitamin D.

As you probably know by now, vitamin D is formed in your skin from exposure to sunlight. The vitamin D then goes directly to the genes in your skin where it helps prevent the types of abnormalities that ultraviolet light causes.

Hence, when you avoid the sun entirely, or slather on sun block whenever you go out, your skin is not making any vitamin D, and you're left without this built-in cancer protection.

This is one of the primary reasons for the rise in melanoma!

Vitamin D – the Key to All Cancer Prevention?
Continuing on to address the rise in cancers of all kinds, you find that vitamin D is a MAJOR player here as well.

Researchers have discovered that at least 16 different types of cancer can be prevented by increasing vitamin D levels, including pancreatic, lung, breast, ovarian, prostate, and colon cancers. As you can see, these include the three most common cancers, as well as the most deadly.

Optimizing your vitamin D levels can cut your risk by as much as 60 percent, so just imagine the reduction in worldwide prevalence that could be accomplished if the importance of vitamin D became common knowledge!

As a reader of this newsletter, you are ahead of the game.

Just remember that to reap the benefits you need to make sure your vitamin D levels are within therapeutic range. For all the latest information on therapeutic vitamin D levels, and vital updates on testing and updated dosing recommendations, please review my article: Test Values and Treatment for Vitamin D Deficiency.

Pesticide Use is Taking Its Toll
In addition to science finally discovering the impact of vitamin D deficiency on cancer rates, researchers are also finding strong links between pesticide exposure and cancer.

A new study illustrates how profound of an effect pesticide exposure during childhood can be on future health. Researchers found that women who worked on farms when growing up had a greater risk of developing breast cancer.

According to Sustainable Food:

"Some pesticides and farm chemicals are carcinogens, while others mimic estrogen. Chemicals that mimic estrogen are linked to cancer and other diseases, particularly if exposure occurred during childhood."

The answer, of course, is to promote organic farming and eat as much organically-grown foods as you can.

As Sustainable Food says, "those kinds of chemicals shouldn't be near our cucumbers, much less near our children." Keep in mind that although farmers are physically exposed to the pesticides they use during the course of their work, you and your children are consuming these same pesticides with every bite of conventionally-grown food you eat.

Although the level of exposure may be less than a farm worker, the chronic exposure from eating pesticide-laden food day in and day out for years can cause tremendous harm.

Healing Foods Come to the Fore
The good news is, cancer research keeps discovering the power of foods against cancer.

According to a Texas A&M AgriLife press release, their researchers have found that breast cancer cells, even those of the most aggressive type, can be killed with extracts of peach and plum, while leaving normal cells unharmed.

Two phenolic compounds, which occur naturally in fruits, are believed to be responsible for the cancer cell deaths.

The press release reads:

"It was a differential effect which is what you're looking for because in current cancer treatment with chemotherapy, the substance kills all cells, so it is really tough on the body," said Dr. David Byrne, AgriLife Research plant breeder who studies stone fruit.

"Here, there is a five-fold difference in the toxic intensity. You can put it at a level where it will kill the cancer cells - the very aggressive ones - and not the normal ones."

Byrne and Dr. Luis Cisneros-Zevallos originally studied the antioxidants and phytonutrients in plums and found them to match or exceed the blueberry which had been considered superior to other fruits in those categories."

Again and again we see promising results such as these. A number of plants, fruits, herbs and spices have been identified as having potent anti-cancer properties that could offer effective prevention. Others show potential in the actual treatment of cancer.

Examples include:

•Broccoli
•Sweet wormwood plant (Artemisia annua L)
•Black cohosh
•Black raspberries
•CLA from grass-fed beef and grass-fed dairy products
•Huang qin
For even more examples, please review the related articles below, and for a comprehensive list of all my cancer prevention strategies, please see this previous article.

The signs are clear, there's plenty you can do to prevent cancer from happening to you, and it starts with living as purely as you can, and eating as healthy as possible.
