Uterine Cancer Study Act of 2025

HR 4396, the Uterine Cancer Study Act of 2025, mandates a study by the Department of Health and Human Services (HHS) into the potential link between chemical hair straighteners and uterine cancer, with a specific focus on higher incidence rates among women of color. The study will review existing research, examine impacts across all racial and ethnic groups, analyze different hair straightener types (including those with dyes or bleach), and assess whether the FDA should require additional safety testing for these products. HHS must submit its study methodology within 45 days of the bill's enactment, begin the study within 180 days, and deliver a final report to Congress within two years. This bill does not create new regulations but directs a specific research effort to gather evidence on a potential health concern. The study directly affects women, particularly women of color, who use hair straightening products and may face elevated uterine cancer risks.
