Incidence – A cancer incidence rate is the number of new cancers of a specific site/type occurring in a specified population during a year, usually expressed as the number of cancers per 100,000 population at risk. That is,

Incidence rate = (New cancers / Population) × 100,000
The numerator of the incidence rate is the number of new cancers; the denominator is the size of the population.
