Cancer Prevalence: How Many People Have Cancer? Cancer prevalence is defined as the number of living people who have ever been diagnosed with cancer.

Population-Based Incidence and Prevalence of Systemic Lupus Erythematosus The overall age-adjusted incidence and prevalence (ACR definition) per 100,000 persons were 5.5 (95% confidence interval [95% CI] 5.0–6.1) and 72.8 (95% CI 70.8–74.8). Among females, the incidence was 9.3 per 100,000 persons and the prevalence was 128.7 per 100,000 persons. Only 7 cases were estimated to have been missed by capture–recapture, adjustment for which did not materially affect the rates.
