A large medical centers oncology program reported an increased number of cases of pancreatic cancer during a certain month. The hospitals 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:

	Cancer Patients	Other Patients
	Men	Women	Men	Women
LIFESTYLE VARIABLE
Alcohol	185	120	270	260
Tea Drinking	140	110	230	225
Coffee Drinking	190	140	270	240

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.
