Screening Test
Definition
A screening test is a procedure that is performed to detect the presence of a specific disease. The individual or group of individuals (as in mass screenings) does not present any symptoms of the disease.
Purpose
The purpose of a cancer screening test is to identify the presence of a specific cancer in an individual that does not demonstrate any symptoms. Screening allows for early detection of cancer and can save the life of the person who might have died if the cancer was not detected by screening. If cancers are detected early, the treatment can be more effective and often less costly than if the cancer had progressed and needed drastic treatment.
