Book: Clinical Oncology

Synopsis:

Frequency measures of this pathology play an important role in any epidemiological explanation; however, they can be confused with similar situations, which is why it is important to start by defining them correctly.

Prevalence measures describe the proportion of the population suffering from the pathology under analysis at a given time; these patients may be new cases or survivors of the pathology. Incidence measures, however, refer only to the number of new cases that appear within a defined period of time. Prevalence is of course dependent on incidence, as well as on the duration of oncological diseases, changes in recovery, or patient life expectancy.
