Does hair dye, lipstick, makeup, or house cleaning detergent cause breast cancer? What about canned goods that have chemicals that mimic estrogen?

there are some studies in animals that have found certain types of plasticizers (compounds put into plastics to make them harder) can accelerate breast cell growth in animals and have a number of other effects on reproduction and the endocrine system, especially in baby boys.

There have also been case reports that we describe on our website, showing that young black baby girls who developed premature breast growth between the ages of 1 and 3 years had been exposed to hormones from personal care products, which their parents had used on their daughters' hair and scalps. When this exposure stopped, the breasts went away in these baby girls. Unfortunately, very few people know about this problem.

But Dr. Chandra Tiwary, who is a pediatric endocrinologist, reported a case series of young girls with premature breast growth and exposure to hormones in hair products. He also documented finding a hormone in a number of widely used personal care products in the African-American community. The FDA does not regulate personal care products unless they are officially called “hormones.” These products are not identified as hormones. Dr. Tiwary made his report about 7 years ago, but these products are still on the market. Certainly anything that can cause a baby girl to develop breasts is a problem.
