The oncology program of a large medical center reported an increase in the number of pancreatic cancer cases during a given month. The hospital epidemiologist decided to investigate the problem. Tumor registries were searched to identify all cases of pancreatic cancer over a five-year period; cancer patients were matched with patients treated for other diseases during the same five-year period. All study subjects were asked about lifestyle factors, including alcohol, tea, and coffee consumption. The resulting data is as follows:

DATA
	cancer patients		other patients
	Men	Women	Men	Women
LIFESTYLE VARIABLE
Alcohol	185	120	270	260
drink tea	140	110	230	225
drink coffee	190	140	270	240

Note: Total number of male cancer patients = 200.

Total number of women with cancer = 150.

Total number of male patients (other diseases) = 300.

Total number of female patients (other diseases) = 300.
