Preventive screenings are medical tests performed to detect potential health issues before symptoms appear. These screenings can help identify conditions such as high blood pressure, diabetes, and certain types of cancer, allowing for early intervention and better treatment outcomes. Common examples include mammograms for breast cancer and cholesterol tests for heart health. Regular preventive screenings are essential for maintaining overall health and can vary based on age, gender, and risk factors. Health professionals often recommend specific screenings at certain intervals, ensuring individuals stay informed about their health status and can take proactive steps to prevent serious illnesses.
