Data extracted from a regional cancer registry was used to investigate the extent
to which smoking increases the risk of breast cancer. The cumulative incidence
of breast cancer was estimated to be 700 cases of breast cancer per 100,000
population for current smokers and 500 cases of breast cancer per 100,000
among never smokers. The overall incidence of breast cancer in the regional
population was estimated to be 562 cases per 100,000.
(A)
What is the relative risk of breast cancer for a current smoker compared
with a non-smoker? Interpret this result - i.e. how strong of a risk factor
does smoking appear to be in the development of breast cancer?
(B)
Estimate the population risk difference / attributable risk of breast cancer
in this population. Interpret the meaning of this result.
