Exposure to parabens may be linked to an increased incidence of breast cancer in Black women

According to a new study presented Sunday at ENDO 2022, the Endocrine Society's annual meeting in Atlanta, Ga., parabens, which are commonly found in hair and personal care products, produce negative effects on breast cancer cells in Black women.

Breast cancer affects one out of every eight women in the United States at some point in their lives. Breast cancer is more common among black women under the age of 40 than in any other racial or ethnic group.

Exposure to hazardous compounds known as endocrine-disrupting chemicals found in hair and personal care products could be one cause of the increased risk of breast cancer. The actions of these substances on the body are similar to those of hormones."

Parabens are endocrine-disrupting compounds that are often used in hair and other personal care products as preservatives. Breast cancer cells proliferate, invade, spread, and express genes linked to cancer and hormone function when exposed to parabens. Importantly, a survey of products that are free of parabens and other hazardous chemicals found that there are less paraben-free options available for Black women.

"We don't have a lot of research about how parabens may enhance breast cancer risk in Black women," Trevio said. "Black women are more likely to buy and use hair products with these types of chemicals." "This is because most research studies looking at this link have not included Black women, and studies to test this link have solely employed breast cancer cell lines from white women."

The effects of parabens on breast cancer cells in Black women were investigated in a new study. Parabens accelerated the growth of a Black breast cancer cell line, according to the researchers. At the levels examined, this impact was not observed in the white breast cancer cell line. In both Black and white women's breast cancer cell lines, parabens boosted the expression of genes linked to hormone activity. Parabens also aided the spread of breast cancer cells, with the Black breast cancer cell line showing a stronger effect.

"These findings add to the growing body of evidence that parabens kill breast cancer cells from Black women," Trevino added.

The research is part of the Bench to Community Initiative (BCI), a community-led project that brings together scientists and community participants (including breast cancer survivors) to find strategies to eliminate dangerous chemicals in hair and personal care products in Black women with breast cancer.

"While the focus of this investigation is on Black women, the knowledge we gather about the link between exposure to dangerous chemicals in personal care items and breast cancer risk may be applied to all women at high risk of breast cancer," Trevino said.
