Possible Environmental Risk
Whatever the evidence, or lack thereof, I think we all suspect that there are environmental factors that likely contribute to the growth of cancer. It is very difficult for careful research to be accomplished as it is virtually impossible to tease out individual factors. For example, how can we possibly know if our own breast cancer diagnosis was influenced by childhood exposure to DDT or dry cleaning fluid or preservatives in food? We can't. This is a report from Health Day that looks at the danger of heavy metal in food and cosmetics.

Can Heavy Metal in Foods, Cosmetics Spur Breast Cancer Spread?
Preliminary study suggests danger from prolonged exposure to cadmium
MONDAY, April 23 (HealthDay News) Prolonged exposure to low levels of the heavy metal cadmium may fuel the growth of some breast cancer cells and encourage them to spread, preliminary research indicates.
Found in many farm fertilizers, cadmium can make its way into soil and water. Some other main sources of cadmium include cigarette smoke, rechargeable batteries, certain cosmetics, bread and other cereals, potatoes, root crops and vegetables. Once it enters the body, cadmium may mimic the effects of the female hormone estrogen.
Unlike previous research, this new analysis looks at lifetime exposure to cadmium, not acute bursts of high levels of the heavy metal.
This research is still in its infancy, explained study author Maggie Louie, an associate professor of biochemistry at the Dominican University of California, in San Rafael.
