Q6. What is the annual incidence rate (per 1,000 persons) of lung cancer, if it is diagnosed in 70 patients per year within a community of 30,000 unaffected individuals? (Please show your calculations) [ONE POINT]

Q7. Colon cancer is diagnosed in 20 patients per year within a community of 10,000 unaffected individuals. Half of the affected individuals die from colon cancer. What is the case fatality of colon cancer in this community? (Please show your calculations) [ONE POINT]

Q8. Breast cancer is diagnosed in 20 patients per year within a community of 10,000 unaffected individuals. A screening test is applied to all residents of this community. What is the sensitivity (in %) of the screening test, if it detects 9 of the breast cancers. What is the specificity if the test correctly determines that 9,900 of the unaffected persons do not have breast cancer? (Please show your calculations)

Q9. A physical examination and an audiometric test were given to 500 persons with suspected hearing problems, of whom 400 were actually found to have them. The results of the examinations were as follows:

C. The occurrence of illnesses of similar nature clearly in excess of the normal expectation for that population at that time (this helps in vigorous management of the disease at that time to prevent its spread)

Sensitivity is the ability of the test to correctly identify those individuals who have the disease. False negative is when testing equipment provides a negative result in a patient who has the disease (Gordis, 2009).

Example: a glucometer may show high level of glucose in a newly diagnosed Diabetic patient this is called sensitivity, while in the glucometer can show low blood glucose in a patient with high blood sugars.
