Screening guidelines are recommendations designed to help identify diseases or health conditions in individuals who may not yet show symptoms. These guidelines are typically developed by health organizations, such as the U.S. Preventive Services Task Force, based on research and evidence about the effectiveness of various screening tests. The purpose of screening is to detect potential health issues early, allowing for timely intervention and better health outcomes. Common screenings include tests for breast cancer, cervical cancer, and high blood pressure, among others. Following these guidelines can help individuals make informed decisions about their health care.
