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

There are very few epidemiological data that point to any specific product or any specific chemicals as being a cause of human breast cancer. Many of these products and chemicals, when given to laboratory animals, increase the frequency of mammary cancer and therefore are worrisome. In the world today, we are exposed to many agents, some of them naturally occurring and some of them man-made, that either cause direct genetic damage and therefore might be able to produce cancers, or which alter our hormone levels which might encourage cancerous cells to grow.

But it's very difficult with all of these chemical exposures that are a daily event in our lives to know which are important. And so, when it comes to risk reduction and trying to decide whether to use a particular product or eat a particular kind of food, there are very few hard and fast recommendations other than to cut down on your exposures whenever you can.
