Scientific studies have indicated that even at very low doses, BPA can increase breast and ovarian cancer growth and the growth of some prostate cancer cells in animals. Health Canada has posted the data on its website but down play their findings. The soft drink industry has told consumers their canned products don't expose drinkers to BPA.

BPA leaches into drinks from the lining of pop cans, which prevent soft drinks from coming into contact with metal. The highest concentration of BPA detected in a single serving of pop was 4.5 parts per billion. BPA was detected in energy drinks, ginger ales, diet colas, root beers and citrus-flavored sodas.
