stressScientists have discovered that everyday emotional stress is a trigger for the growth of tumors. Any sort of trauma, emotional or physical, can act as a "pathway" between cancerous mutations, bringing them together in a potentially deadly mix.

The findings seem to show for the first time that the conditions for developing the disease can be affected by your emotional environment, including everyday work and family stress.

Until now, scientists believed more than one cancer-causing mutation needed to take place in a single cell in order for tumors to grow.

But researchers showed that mutations can promote cancer even when they are located in different cells, because stress opens up "pathways" between them.

I have long believed that emotional factors are one of the most important contributing factors for all diseases, especially cancer.

That is why an effective strategy to manage your emotional stress has long been a part of my 12 top cancer-prevention tools, and this is because there is overwhelming evidence that your mind does matter when it comes to preventing, or triggering, disease.

The idea that your emotions impact your health and the development of disease is not new. Even the conservative Centers for Disease Control and Prevention (CDC) has stated that 85 percent of all diseases appear to have an emotional element, but the actual percentage is likely to be even higher.

Dr. Hamer’s research, which spans across the last three decades, has produced scientific proof indicating that your current health status is due to your mental and emotional reactions to events that take place during your lifetime.

Bruce Lipton’s “New Biology” is another school of scientific thought that adds to this “new” way of thinking about disease, namely that your emotions can trigger your genes to either express health or disease.

Stress Has Been a Known Cause of Cancer Since 1908

I recently finished a fascinating interview with Donald (“Donnie”) Yance, an internationally known herbalist and nutritionist. During our talk he shared this phenomenal piece of information with me: stress was pinned down as a cause of cancer all the way back in 1908! As Donnie said:

“Eli Jones, the great eclectic physician in cancer, and probably the most brilliant person that ever lived on the face of the planet -- I rarely talk without mentioning his name -- wrote a book in 1908 called Cancer - Its Causes, Symptoms and Treatment.

There isn’t one inaccuracy I can find in that book, written more than a hundred years ago.”

In this book, Dr. Jones revealed his top causes of cancer … and the number one cause he listed was stress.

How Does Stress Cause Cancer?

Emotional stress likely triggers cancer in a multi-faceted way.

For instance, the study by Yale University researchers listed above found that stress, even the “normal” everyday variety, can act as a pathway between cancerous mutations, potentially triggering the growth of tumors.

The National Cancer Institute, meanwhile, has said that research with animal models suggests that “your body’s neuroendocrine response (release of hormones into your blood in response to stimulation of your nervous system) can directly alter important processes in cells that help protect against the formation of cancer, such as DNA repair and the regulation of cell growth.”

Still other research has shown that norepinephrine, a hormone produced during periods of stress, may increase the growth rate of cancer.

Norepinephrine can stimulate tumor cells to produce two compounds (matrix metalloproteinases called MMP-2 and MMP-9) that break down the tissue around the tumor cells and allow the cells to more easily move into your bloodstream.

Once there, they can travel to other organs and tissues and form additional tumors, a process called metastasis.

Norepinephrine may also stimulate the tumor cells to release a chemical (vascular endothelial growth factor, or VEGF) that can aid in the growth of the blood vessels that feed cancer cells. This can increase the growth and spread of the cancer.

The stress hormone epinephrine has also been found to cause changes in prostate and breast cancer cells in ways that may make them resistant to cell death. This means that emotional stress could both contribute to the development of cancer and reduce the effectiveness of treatments.

Nourishing Your Emotional Health is an Important Cancer Prevention Strategy

If your emotions play such a significant role in your health, and I’m convinced they do, treating your emotions becomes an essential part of optimal health.

But how?

Learning how to use tools such as the Meridian Tapping Technique (MTT), for example, which works on several levels of your collective mind-body-spirit simultaneously, can help you get a better handle on your emotions and buried pain.

Optimal health involves addressing and resolving your emotional traumas as quickly as possible; without letting old emotional wounds contribute to disease.

So in addition to using MTT as your primary stress resolution tool, you may also want to engage in regular exercise to normalized your insulin level, yoga, journaling, breathing techniques and other tools to put your mind at ease.

There are other important cancer-prevention strategies as well, such as optimizing your vitamin D levels and eating fewer processed foods and sugars, and I’ve detailed my complete anti-cancer lifestyle suggestions here.

But it is likely that your emotional health may be a more important factor than all the other physical ones listed there, so make sure this is addressed -- and do so sooner, rather than later -- for the sake of your future health.

One in Five U.S. Teenagers Has High Cholesterol

teens, teenagersA study by the U.S. Centers for Disease Control and Prevention (CDC) has found that over 20 percent of teenagers in the U.S. have elevated cholesterol levels.

The national study covered more than 3,000 teens whose blood test results were collected by the National Health and Nutrition Examination Survey.

High levels of LDL or triglycerides, and low HDL levels were associated with weight, and the heavier the teenagers were, the more likely they were to have abnormal levels (nearly 43% if they were obese), but even among those with normal body weight over 14% had unhealthy levels.

High cholesterol levels were at first associated with the middle-aged and elderly, but are increasingly beginning to appear in late childhood and the teenage years.

This finding already has researchers urging cholesterol screening for about one-third of teens who are overweight or obese, which will put many of these kids right in the line of fire to be prescribed a dangerous statin drug.

In 2007, the American Heart Association first recommended the use of statin drugs for children with high cholesterol. Then in 2008 the American Academy of Pediatrics followed suit, recommending cholesterol-lowering drugs for children as young as 8!

There is such overwhelming evidence -- nearly 900 studies compiled in this link -- showing the damage statins inflict, that this recommendation should qualify as criminal malpractice.

Some of the possible consequences of taking statins for a lengthy period of time, which many of these kids undoubtedly would do, include:

  • Cognitive loss

  • Neuropathy

  • Anemia

  • Acidosis

  • Frequent fevers

  • Cataracts

  • Sexual dysfunction

Then there is the serious risk of potentially permanent muscle damage, and the depletion of Co-Q10, which can harm your heart and muscles alike.

Statin drugs used to lower cholesterol are the best-selling drugs in the United States. In 2008 alone they brought in $14.5 billion in sales!

The odds are very high, greater than 100 to 1, that anyone taking statin drugs does not need them. The ONLY subgroup that MAY benefit are those born with a genetic defect called familial hypercholesterolemia, as this makes them resistant to traditional measures to normalize cholesterol.

And the first step to understanding why lies in understanding the role of cholesterol in your health, not in disease.

Why Cholesterol is Not “Evil”

Cholesterol has been traditionally vilified, when in reality it is essential and crucial for a wide variety of vital functions in your body.

It’s an integral part of your cell membranes, and it’s also the precursor (the raw material) your body uses to make your steroid hormones – one of which is vitamin D. Your skin contains cholesterol, and when UVB rays from the sun hit your skin, it converts that form of cholesterol to vitamin D3, which is then transported to your blood. Your body then further converts it into the active form of vitamin D.

It’s important to realize that there’s a big difference between "average" and "healthy" cholesterol levels. It’s very similar to what we’re now seeing with vitamin D levels.

Please understand that you have not been told the whole truth about cholesterol. Rather, what you’re getting from most conventional health practitioners is little more than cleverly distorted marketing.

Before 2004, a 130 LDL cholesterol level was considered healthy. The updated guidelines, however, recommended levels of less than 100, or even less than 70 for patients at very high risk.

In order to achieve these outrageous and dangerously low targets, you typically need to take multiple cholesterol-lowering drugs. So the guidelines instantly increased the market for these dangerous drugs. Now, with testing children’s cholesterol levels, they’re increasing their market even more.

Total Cholesterol Level is a Virtually Useless Test

If your doctor is urging your child to get a total cholesterol level check, you should know that this test will tell you virtually nothing about his or her risk of heart disease -- unless it is 330 or higher.

And, perhaps more importantly, you need to be aware that cholesterol is not the CAUSE of heart disease.

If you become overly concerned with trying to lower your child’s cholesterol level to some set number, you will be completely missing the real problem.

In fact, I have seen a number of people with levels over 250 who actually were at low heart disease risk due to their elevated HDL levels. Conversely, I have seen even more who had cholesterol levels under 200 that were at a very high risk of heart disease based on the following additional tests:

  • Your HDL/Cholesterol ratio

  • Your Triglyceride/HDL ratios

HDL percentage is a very potent heart disease risk factor. Just divide your HDL level by your cholesterol. That percentage should ideally be above 24 percent. Below 10 percent, it’s a significant indicator of risk for heart disease.

You can also do the same thing with your triglycerides and HDL ratio. That percentage should be below 2.

How to Get Your Children Healthy

While I don’t believe high cholesterol is typically a concern (again unless it is over 330), many teens are overweight, obese or showing signs of being at risk of heart disease based on the tests I described above.

In this case, you do need to take some steps to help him or her get healthy.

Fortunately, there are simple, basic strategies that can help your teen not only regulate cholesterol in a healthy way, but also build a foundation for a healthy heart and body that will support him throughout his life.

  1. Get an appropriate amount of exercise.

  1. Reduce, with the plan of eliminating, grains and sugars in your daily diet. Foods like these will increase your insulin levels, which will also contribute to high cholesterol by making your liver produce more of it.

  1. Eat the right foods for your nutritional type.

  1. Eat a good portion of your food raw.

  1. Make sure you’re getting plenty of high-quality, animal-based omega3-fats. I prefer those from krill oil.

  1. Avoid smoking and alcohol.

  1. Have solid strategies to address your emotional challenges.

Finally, please do make sure your, and your child’s, vitamin D levels are where they need to be. Vitamin D is not “just a vitamin,” but rather the only known substrate for a potent, pleiotropic (meaning it produces multiple effects), repair and maintenance seco-steroid hormone that serves multiple gene-regulatory functions in your body.

Low levels of vitamin D are associated with an increased risk of heart disease, which is what parents of teens with “high” cholesterol are most concerned about.

About 70 percent of U.S. children have low levels of vitamin D, so this should be one of the one of the first issues you address to keep your teen’s heart healthy.
