^aCases with unknown county were excluded

^bFemale population estimates were obtained from US Census Bureau's Population Estimates Program

^cIncidence rate was number of cases per 100,000 population, and was age adjusted to the 2000 US population

^dBreast cancer early stage includes in situ and localized. Late stage includes regional and distant
