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:
