Hair-Straightening Products Linked With Uterine Cancer Risk: Study
Hair-straightening products may significantly increase the risk of developing uterine cancer among those who use them frequently. However, it is important to put this information into context. Uterine cancer is a relatively rare type of cancer. Still, uterine cancer is the most common gynecologic cancer in the United States, according to the U.S. Center for Disease Control and Prevention (CDC), with rates rising, particularly among Black women.
@niraj Researchers tracked 33,947 racially diverse women, ages 35 to 74, for an average of nearly 11 years. During that time, 378 women developed uterine cancer. After accounting for participants' other risk factors, the odds of developing uterine cancer were more than two and a half times higher for women who had used straightening products more than four times in the previous year. Less frequent straightener use in the past year also was associated with an elevated uterine cancer risk, but the difference was not statistically significant, meaning it might have been due to chance. Earlier studies have shown that hair straighteners contain so-called endocrine disrupting chemicals. The products have previously been associated with higher risks of breast and ovarian cancer.
