A New Study Links Hair Dye with Increased Breast Cancer Risk

When asked whether women should immediately stop dyeing or straightening their hair, co-author Dale Sandler said, “We are exposed to many things that could potentially contribute to breast cancer, and it is unlikely that any single factor explains a woman’s risk. While it is too early to make a firm recommendation, avoiding these chemicals might be one more thing women can do to reduce their risk of breast cancer.”

Lead author Alexandra White agrees. She told Today: “We know that a lot of different factors influence a woman’s risk of developing breast cancer, and these risks we see here, they are meaningful but they are small […] Women should take that into context with everything else in their life, including their physical activity and diet. These are all factors we have to consider when we’re thinking about our long-term health risks.”
