Cancer statistics are used to monitor the incidence of new cancer cases and the survival and mortality of cancer patients. The statistics of the Mass Screening Registry are used in evaluation and quality control of cancer screening.
Cancer research focuses on identifying the causes of cancer in the population, prevention and the early detection of cancer, together with factors affecting the survival of cancer patients.
Cancer screening is the systematic search for the precursors or early stages of cancer from among the population. The goal is to reduce deaths due to cancer among those screened.
