Screening tests are medical procedures used to detect potential health disorders or diseases in individuals who do not yet show symptoms. These tests aim to identify conditions early, allowing for timely intervention and better health outcomes. Common examples include mammograms for breast cancer and cholesterol tests for heart disease. The importance of screening tests lies in their ability to catch diseases at an early stage when they are often more treatable. Regular screenings can lead to improved survival rates and overall health. Health professionals recommend specific screening tests based on age, gender, and risk factors.
