NCI: The use of any device, marker, or other means for the purpose of detecting the presence of disease, usually in asymptomatic individuals.,NCI: Checking for disease when there are no symptoms. Since screening may find diseases at an early stage, there may be a better chance of curing the disease. Examples of cancer screening tests are the mammogram (breast), colonoscopy (colon), Pap smear (cervix), and PSA blood level and digital rectal exam (prostate). Screening can also include checking for a person's risk of developing an inherited disease by doing a genetic test.
