Scientists are uncovering new details in the connection between using certain hair straightening products, such as chemical relaxers and pressing products, and an increased risk of cancer in women.
Ongoing research previously suggested that hair straightening chemicals are associated with an increased risk of certain hormone-related cancers, including breast and ovarian cancers, and now, a new study links use of hair straightening products with an increased risk of uterine cancer. Black women may be more affected due to higher use of the products, the researchers noted.
The study, published Monday in the Journal of the National Cancer Institute, estimates that among women who did not use hair-straightening chemical products in the past 12 months, 1.6% developed uterine cancer by age 70, but about 4% of the women who frequently use such hair-straightening products developed uterine cancer by age 70.
That finding “also communicates that uterine cancer is indeed rare. However, the doubling of risk does lead to some concern
Black women, who made up only 7.4% of the study participants, but 59.9% of those who reported ever using straighteners.
