Screening

Definition: Using tests or other methods of diagnosis to find out whether or not a person has a specific disease or condition before it causes any symptoms. For many diseases (for example, cancers), starting treatment earlier leads to better results. The purpose of screening is to find the disease so that treatment can be started as early as possible.

Example: For example, a breast exam and a mammogram are both screening tests used to find small breast cancers.
