Study Shows Possible Link Between Breast Cancer, Stress

Researchers find stress-cancer link after diagnosis

A new study suggests that stress may be linked to breast cancer for some women.

"The scientific community really is only beginning to understand what stress means biologically," said study author Garth Rauscher.

The biological connection may be due to the way stress affects hormones, researchers said. We already know hormonal levels may play a role in the development of certain breast cancers.

In this study, the link was found to be highest among African American and Hispanic breast cancer patients.

The authors did point out that the link was not proof of cause and effect, because patients filled out stress questionnaires after diagnosis. Thus, it is unclear whether the cancer caused the stress or vice versa.

"The nature of the timing of the collection of information makes it impossible to know what's responsible for what," Rauscher said.

More study is needed, including research about stress levels done before someone develops cancer.

In the meantime, since we do know that reducing stress strengthens our immune systems and helps us fight disease, the best advice is to reduce stress by sharing your feelings rather than holding them inside, and seek professional help if you feel that you are not dealing well with the stress in your life.
