This is an interesting new study that I read about that links stress to aggressive breast cancer tumors.

THURSDAY, Sept. 22 (HealthDay News) — A new study finds that black and Hispanic women with breast cancer suffer more stress than white women, and the researchers connected the extra stress to more aggressive tumors.

But, the study authors cautioned that the research is preliminary and doesn’t provide insight into whether the women’s stress levels already were high before diagnosis, whether the stress levels increased after diagnosis, or whether the increased stress caused the cancer to be more aggressive.

Still, the findings point to one possible — if unconfirmed — explanation why breast cancer is generally worse in black and Hispanic women, said study lead author Garth H. Rauscher.

“One possible reason for that, among others, could be differences in the role of stress in influencing the development of breast cancer,” said Rauscher, associate professor of epidemiology at the University of Illinois at Chicago’s School of Public Health.
