4. Suppose that you conduct a retrospective cohort study in a particular US state to examine whether a smoking increases the risk of breast cancer. The cumulative incidence of breast cancer is 700/100,000 among the exposed (those who smoke) and 500/100,000 among the unexposed (those who do not smoke). The overall incidence of breast cancer in the entire state is 562/100,000. a. What is the relative risk of breast cancer for a smoker? b. What is risk of breast cancer that can be attributed to smoking in this population?
