CAUSES OF CANCER

 

Environmental Carcinogenesis

An estimated 100,000 synthetic chemicals are believed to be in use today in the United States. Another 1,000 or more are added each year. More than 90 percent have never been tested for their effects on human health. Many of these chemicals persist in the environment, accumulate in body fat and remain in breast tissue for decades. Studies by the U.S. Centers for Disease Control and Prevention (CDC) show that Americans of all ages carry a body burden of at least 148 chemicals that have been measured, some of them banned for more than two decades because of toxicity. These studies alone cannot establish cause but can reveal the internal contamination of our bodies by chemicals with known carcinogenic activity.

Patterns of breast cancer incidence indicate the  importance of environmental exposures. Women who move from countries with low breast cancer rates to industrialized countries soon acquire the higher risk of their new country. The largest study ever conducted among twins found that environmental exposures unique to those with breast cancer made the most significant contribution to the development of the disease.
