Examining and/or testing a large number of people who have no symptoms of a particular disease, to identify anyone who may have that disease. This enables the disease to be treated at an early stage, when cure is more likely. Examples include Pap tests to detect precancerous changes of the cervix, and mammography to screen women for early breast cancers.

Screening Test

A test done on all people at risk of developing a certain disease, even if they have no symptoms. Screening tests predict the likelihood of someone having or developing a particular disease. The Pap test is a screening procedure to look for changes that might lead to cancer of the cervix. It is up to 90% accurate and the best way to prevent squamous cancer of the cervix.
