Notes:
Age-Adjusted Rates are per 100,000 population. Age-adjusted rates are computed by the direct method, using as the standard population the age distribution of the total population of the United States for the year 2000. Adding and subtracting the number shown after the ± symbol from the rate creates a confidence interval indicating that the true rate lies between the lower and upper bounds of this interval with 95 % statistical confidence. COVID-19 Pandemic: In 2020, the highly publicized impact of the COVID-19 pandemic on health services and the consequential delays and reductions in cancer screening and diagnosis led to a decline in the 2020 incidence rates for most cancer sites. Because 2020 was a temporary, anomalous year, it can bias estimates such as cancer incidence trends. Average Number is the number of new invasive cancer cases diagnosed in the period, divided by the number of years in the period. : A rate is not calculated when there are fewer than 20 events, because the width of the confidence interval would negate any usefulness for comparative purposes.
