Abstract

Conventional cancer incidence rates reported in the United States represent the number of newly diagnosed cases in a given year divided by the mid-year population for that year (1). Incidence rates have been reported on an annual basis in the United States since 1973, when the National Cancer Institute initiated the Surveillance, Epidemiology, and End Results (SEER) Program (2). Population-based site-specific cancer incidence rates are commonly thought of as measures reflecting the average risk of developing the disease (3). However, this assumes that the rate calculation includes new cases of the cancer in the numerator and the at-risk population for developing the cancer in the denominator. In other words, a measure of the risk of developing a given cancer should be new cases of the disease divided by those who have never had the disease but are at risk of developing it (4).
