More Evidence Stress and Cancer are Linked

Norepinephrine, a hormone produced during periods of stress, may increase the growth rate of cancer.

The 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 the 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.

Researchers traced the harmful effect of norepinephrine after applying it to cancer cell lines used to study nasopharyngeal carcinoma (NPC), an incurable head and neck cancer associated most frequently with those of Chinese descent.

Dr. Mercola's Comments:

As the evidence builds, conventional medicine is finally beginning to understand how profoundly negative stress can harm your physical health, making you vulnerable to all kinds of diseases like cancer.

It's why, in general, happier people enjoy life far more than worry-warts and are, typically, more physically healthy too.

I've devoted a lot of space on my site to studies that prove, without a doubt, the undeniable connection between emotional and physical health. For example, how a positive mental attitude can play a vital role in maintaining a healthy heart and delaying the aging process naturally.

In contrast, handling stress poorly can shorten your life, interfere with your ability to conceive a child, and, as we see here, hasten the spread of cancer.

Stress is a key factor in any illness and it plays a major role in the health of nearly every one of the more than 20,000 patients I have seen. To completely eliminate stress from your life is virtually impossible, and even undesirable as a stress-free life may actually kill you. We all need some level of stress to keep us healthy.

However, if you don't learn how to address stress in a healthy way, a recent study shows how your brain may actually "rewire itself," altering its connections in such a way so it affects the way the brain functions.

"Magnesium is great for stress. I have MVP, which is a flawed autonomic nervous system causing my heart to race with adrenaline all the time. My heart used to beat 105 bpm resting so you can imagine that I'm chronically stressed out even when I'm bored out of my skull. Since taking 800mg of magnesium my heart went down to 78 bpm on a good day. I was able to think clearer and focus better. All this time I thought I had ADD but it's clearly the stress hormones at work."
