A statistical method allowing comparisons of populations that takes into account age-distribution differences between populations. Most incidence and death data in SEER are age-adjusted, although some [..]

A term related to lifetime risk. The probability of developing cancer starting at a specific age and during a specified number of years.

The rate of incidence or mortality of a specific age group, calculated per 100,000 people.

The average annual percent change over several years. The APC is used to measure trends or the change in rates over time. For information on how this is calculated, go to Trend Algortihms in the SEER* [..]

An annual update of cancer death rates, incidence rates (new cases), and trends in the United States. The Centers for Disease Control and Prevention, the American Cancer Society, the National Cancer I [..]

An estimate of the financial, emotional, or social impact that cancer creates within the population. Different racial, ethnic, geographic, and age groups in the United States do not share the burden o [..]

An annual report containing the most recent incidence, mortality, and survival statistics, published by the Cancer Statistics Branch of the NCI. It presents a broad profile of the cancer burden.

A joint effort by several organizations to develop standard computerized methods for determining the stage of cancer based on tumor size, extension of the primary tumor, lymph node involvement, and me [..]

An estimated range of values which is likely to include an unknown population parameter. The 95% (p-value = .05) and 99% (p-value = .01) confidence intervals are the most commonly used. If an estimate [..]

The crude probability of death measures the mortality patterns actually experienced in a cohort of cancer patients on which many possible causes of death are acting simultaneously.
