Getting regular checkups and preventive screening tests are among some of the most important things you can do for yourself. "Health screenings are tools for preventing disease and determining if people are at risk for developing a medical condition that could eventually affect their health or lifestyle," explained Family Practice physician Libre Johnson, M.D. "Heart disease, stroke, diabetes and other diseases may be treated or prevented if they are found early. Health screenings refer to a test or exam that is performed to find a medical condition in its early stages, when it is easier to treat. The types of screenings a person needs depends on his or her age, sex, family history and whether there are risk factors for certain diseases." According to the U.S. Preventive Services Task Force (USPSTF), the screening tests that follow are recommended as tools for the early detection of disease, since they can lead to prevention and treatment that saves lives.
