cancer prevalence

Cancer prevalence refers to the total number of people living with cancer at a given time, including those recently diagnosed and those who have survived for years. It reflects how common cancer is within a population. Prevalence is influenced by factors like the incidence rate (new cases), survival rates, and population size. Advances in detection and treatment mean more people survive longer, increasing prevalence even if new cases stay stable. Understanding prevalence helps healthcare providers allocate resources, plan treatments, and support services for individuals affected by cancer.
