Actusante.net NEWS Uterine cancer: Hair straightening products would increase the risk News > Cancer By Jerome, published on October 19, 2022 at 10:24 am. Illustrative photo. Curly hair. The study published today specifies that this risk is doubled compared to women who do not use these products. According to a large study by the United States National Institutes of Health (NIH), hair straightening products are likely to increase the risk of uterine cancer. Alexandra White, lead author of this study published in the Journal of the National Cancer Institute, summarizes: We estimate that 1.64% of women who have never used a hair straightening product will have developed uterine cancer by their 70s, but for frequent users, this risk increases to 4.05%. “A worrying doubling” This cancer is not to be confused with that of the cervix. In this case, these are cancers such as those related to the endometrium. This risk is based on the use of hair straightening products more than 4 times a year. Data from the NIH study includes more than 33,000 women aged 35 to 74, followed for nearly 11 years. During this time, 378 cases of uterine cancer were diagnosed. “The doubling of this rate is worrying”, still indicates Alexandra White while adding that “it is important to put this information in context, cancer of the uterus is a relatively rare form of cancer”. It accounts for 3% of new cancer cases in the United States. Black women more exposed Che-Jung Chang, who participated in this study, points out for her part: Because black women use straightening or straightening products more frequently and tend to start younger (…), these results could be of particular interest to them. In this study, about 6 in 10 women who reported using such products in the past year identified as black. Specifically, hair straightening products are likely to promote the absorption of chemicals through lesions or burns caused to the scalp, or by the use of straightening irons whose heat breaks down the chemicals.
