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:
Note: 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.
