Population screening, selective detection of the population screening or early diagnosis can be defined as the set of activities  applied to large, unselected populations, which aims to detect the disease before it manifests itself clinically and thus be able to start treatment early in order to improve the prognosis.

1. breast cancer

2. cervical cancer

3. Colorectal cancer.

The benefit of a screening must be measured by the reduction in mortality.
