Oral Cancer screening

Oral Cancer screening aims to detect cancer before symptoms appear. This may involve blood tests, urine tests, other tests, or medical imaging.[1] The benefits of screening in terms of cancer prevention, early detection and subsequent treatment must be weighed against any harms.Universal screening, also known as mass screening or population screening, involves screening everyone, usually within a specific age group. Selective screening identifies people who are known to be at higher risk of developing cancer, such as people with a family history of cancer.
