Stress and Cancer

Scientists have theorized for decades that stress and cancer are directly linked. A new study suggests that the hormones we produce while under stress increase the growth rates of a few very lethal forms of cancer.

The study showed that an increase in norepinephrine, a stress hormone, can stimulate tumor cells to produce two compounds. These compounds can break down the tissue around the tumor cells and allow the cells to more easily move into the bloodstream. From there, they can travel to another location in the body to form additional tumors, a process called metastasis.

The research also suggests the same hormone can also stimulate the tumor cells to release another compound that can aid in the growth of new blood vessels that feed cancer cells, hastening the growth and spread of the disease. The work was reported in the latest issue of the journal Cancer Research.

“This opens up an entirely new way of looking at stress and cancer that’s different from current interpretations,” explained Ronald Glaser, a professor of molecular virology, immunology and medical genetics, and director of the Institute for Behavioral Medicine Research at Ohio State University .

A very interesting read, this article in Science Daily, gets one to think about the benefits of reducing stress in ones life.
