Relation of Carcinoma in Situ to Invasive Carcinoma of the Cervix Uteri

چکیده
The quantitative measurements used to express the rate of occurrence of disease and the magnitude of its accumulation are, respectively, incidence and prevalence. Incidence is the number of cases of a disease being produced by a population over time and is expressed as a rate of production per unit of time per unit of population. Prevalence, on the other hand, is the number of persons in the population having the disease at any moment in time, and as a rate is expressed as the number of cases per unit of population. Prevalence of disease, then, may be looked upon as accumulated incidence.
