Stress and Aggressive Breast Cancer: Cause or Effect?
Medical Author: Melissa Conrad Stöppler, MD
A research study presented at the Fourth AACR Conference on the Science of Cancer Health Disparities in September 2011 revealed an association between psychological stress and one of the most aggressive types of breast cancer.
The study was performed on 989 women with breast cancer. Two to three months after diagnosis, the women were asked to rate their degree of anxiety, fear, and isolation. These self-reported stress scores were higher for black and Hispanic women than in white women. Further, those women who reported having higher levels of stress tended to have more aggressive tumors (defined as being negative for the presence of estrogen receptors, meaning that therapies designed to block the effects of estrogen will not be effective) than those with lower stress levels. The association between stress level and aggressive tumors was strongest in black and Hispanic women.
