Medical News Today: Parabens may increase breast cancer risk in Black women

UC expert comments on implications of recent study

Black women in the United States are 39% more likely to die from breast cancer compared to white women and are more likely to develop breast cancer under the age of 40.

A recent study conducted by researchers at City of Hope in Los Angeles found that compounds called parabens, which are used as preservatives in hair and personal care products, increased the growth of a Black breast cancer cell line but did not increase growth in a white breast cancer cell line.

Xiaoting Zhang, PhD, professor and Thomas Boat Endowed Chair in the University of Cincinnati's Department of Cancer Biology, director of the Breast Cancer Research Program and member of the University of Cincinnati Cancer Center, was not involved in the study but commented on it for Medical News Today.

Zhang said the study findings were interesting and suggest that at least part of the reason why parabens affect cancer cells differently is due to genetic or epigenetic differences.

"It will be highly critical to further study its effect not only in cultured breast cancer cells but also in animal models and eventually in humans,” Zhang said.

Now, as Medscape recently reported, novel clinical recommendations, advanced diagnostic tools and research into inflammation and immune responses, are bringing promise that women with endometriosis will find relief sooner and without surgery, according to experts, including Katie Burns, PhD, University of Cincinnati College of Medicine associate professor.
