Stress and Cancer

Numerous studies show that stress and negative emotions have been linked to the rate of progression for cancer. Researchers have implanted tumor cells into lab rodents, which were then exposed to uncontrollable stress, making them more prone to cancer (Sklar & Anisman, 1981). In the rodents with immune systems weakened by stress the tumors developed sooner and grew larger.

Buck Up Within a Year

Some studies have also shown that people are at increased risk for cancer within a year after experiencing depression, helplessness or bereavement. One large Swedish study revealed that people with a history of work related stress had 5.5 times greater risk of colon cancer than those reporting little or no stress (Courtney Et al., 1993). 

Psychological Inventions

However, when organic causes of illness are unknown, it’s tempting to invent psychological explanations. Prior to the discovery of the germ that causes Tuberculosis, personality explanations of TB were popular (Sontag, 1978).

The emerging view is that stress does not create cancer cells but their growth may be affected by weakening our body’s natural defenses.
