A new screening program was instituted in a certain country. The program used a screening test that is effective in detecting cancer Z at an early stage. Assume that there is no effective treatment for this type of cancer and, therefore, that the program results in no change in the usual course of the disease. Assume also that the rates noted are calculated from all known cases of cancer Z and that there were no changes in the quality of death certification of this disease. What will happen to the apparent incidence rate of cancer Z in the country during the first year of this program?

a. Incidence rate will increase

b. Incidence rate will decrease

c. Incidence rate will remain constant
