Prevalence is a statistic of primary interest in public health because it identifies the level of burden of disease or health-related events on the population and health care system. Prevalence represents new and preexisting cases alive on a certain date. In contrast, incidence reflects new cases of a condition diagnosed during a given period of time. Prevalence is a function of both the incidence of the disease and survival. More information about cancer prevalence estimates and available statistics can be accessed from the Overview of Cancer Prevalence Statistics:
The ComPrev software calculates complete prevalence estimates, based on limited-duration prevalence statistics calculated on SEER cancer data. The ProjPrev software combines populations and prevalence proportions to obtain/project new prevalence proportions. This software is useful to obtain US prevalence proportions for all races combined from race-specific SEER prevalence proportions and race-specific US populations.
