Screening is a form of examination in which people are tested for a disease or condition, even if they have no symptoms yet. The goal is to detect a condition early, when treatment can often be more effective. Screening can consist of blood tests, imaging, or genetic testing, depending on the disease being screened for. On this site, the word appears because screening is used in some incurable diseases to identify the disease early or to detect an increased risk.
