Preventative healthcare refers to the various measures adopted to prevent disease. It has recently gained importance since people are more empowered about their own health and know how important check-ups and screening tests are for early detection and treatment of disease. Check-ups and screening tests are also important in public health since early diagnoses help to reduce costs in tests and treatments. Many factors, such as age, health, family history, and lifestyle choices impact on how often you will need check-ups.
