Exercise 35

Breast cancer, the most lethal form of cancer for women, is associated with exposure to chemicals called PAHs (from car exhaust, tobacco smoke, and industrial air pollution), alcohol, pesticides on food and in drinking water, styrene from food containers, PCBs, dioxin, ionizing radiation, hormone supplements, and solvents in household chemicals. Design an experiment that would test the hypothesis that any one of these chemicals causes breast cancer.
