Medical screening is a process that involves testing individuals for specific diseases or health conditions before they show symptoms in order to detect potential problems early and prevent further complications. Screening tests are often recommended based on risk factors such as age, family history, and lifestyle choices. The goal of medical screening is to identify individuals who may have a higher chance of developing a certain condition so that they can receive timely treatment or preventive measures. Examples of common medical screening tests include mammograms for breast cancer, Pap smears for cervical cancer, and cholesterol checks for cardiovascular disease.
