A large medical center’s oncology program reported an increased number of cases of pancreatic cancer during a certain month. The hospital’s epidemiologist decided to research the problem. Tumor registry records were searched to identify all cases of pancreatic cancer during a five-year period; cancer patients were matched with patients treated for other diseases during the same five-year period. All subjects in the study were questioned about lifestyle factors including alcohol, tea, and coffee consumption. The resulting data are as follows:

Total number of male cancer patients = 200.Total number of female cancer patients = 150.Total number of male patients (other diseases) = 300.Total number of female patients (other diseases) = 300. Which number best approximates risk associated with alcohol drinking in women?
