Question 72
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:

Explanation / Answer
Total number of femals cancer patient drinking tea = 110
Total NUmber of femal cancer patient = 150
Risk associated with tea drinking in femals = 110/150
approximately answer D
If we combine female drinking tea with other diseases then
=225/300
=0.75
Totalling the both =0.75+0.73
approximately answer B
