Screening Tests | Community Health

Screening tests are medical exams or procedures used to detect diseases or conditions in their early stages, often before symptoms appear. These tests can help identify individuals who are at risk of developing a particular disease, allowing for early intervention and potentially improving treatment outcomes. According to the [[world-health-organization|World Health Organization]] (WHO), screening tests can be used to detect a wide range of conditions, including [[cancer|cancer]], [[diabetes|diabetes]], and [[heart-disease|heart disease]]. For example, [[colonoscopy|colonoscopy]] is a screening test used to detect [[colorectal-cancer|colorectal cancer]], which is the third leading cause of cancer deaths worldwide, as reported by the [[national-cancer-institute|National Cancer Institute]]. The [[centers-for-disease-control-and-prevention|Centers for Disease Control and Prevention]] (CDC) recommends regular screening tests for various diseases, including [[breast-cancer|breast cancer]] and [[cervical-cancer|cervical cancer]]. By detecting diseases early, screening tests can help reduce the risk of complications and improve treatment outcomes, as seen in the case of [[pap-smear|Pap smear]] tests, which have been shown to reduce the incidence of cervical cancer by up to 80%, according to the [[american-cancer-society|American Cancer Society]].
