Certain PCBs May Increase Breast Cancer Risk NEW YORK (Reuters Health) Although most studies have failed to detect a link between overall exposure to pollutants called PCBs and an increased risk of breast cancer, the results of a new study suggest that high levels of specific PCBs may be linked to the disease. "Our results suggest that some persistent environmental contaminants that accumulate in the body of women with age and are similar in structure to dioxin may be a risk factor for breast cancer," Dr. Pierre Ayotte, of Laval University in Beauport, Quebec, Canada, told Reuters Health. But Ayotte, who is a co-author of a report on the findings in the American Journal of Epidemiology, cautioned, "The final word is not in, and these results need to be confirmed." Ayotte added that the findings also highlight the importance of additional research "on the possible link between environmental contaminants that can mimic hormones or alter hormone metabolism and the risk of breast cancer."
