Preventive tests are medical examinations conducted to detect potential health issues before symptoms appear. These tests aim to identify diseases early, allowing for timely intervention and better treatment outcomes. Common examples include screenings for breast cancer, colon cancer, and high blood pressure. Regular preventive tests can help individuals maintain their health and reduce the risk of serious conditions. Health professionals often recommend these tests based on age, gender, and family history. By participating in preventive testing, people can take proactive steps toward a healthier future and improve their overall well-being.
