Environmental Contaminants Linked to Breast Cancer

Researchers at Columbia Presbyterian Medical Center in New York have identified a link between exposure to certain environmental contaminants and breast cancer. The experimental study found that polycyclic aromatic hydrocarbons (PAH), environmental contaminants produced by gasoline and oil combustion and also found in cigarette smoke and broiled meat, damaged DNA and caused cancerous cells to develop. The research team found a significant correlation between PAH-DNA damage in breast tissue and breast cancer in women. The study, published in the July issue of Carcinogenesis, suggests that reducing exposure to environmental factors like PAH could help prevent breast cancer.
