How do dentists and hygienists screen for oral cancer?

An initial oral cancer screening should take fewer than five minutes. A patient does not have to do anything special to prepare for an oral cancer screening. The oral healthcare provider will inspect all parts of the inside of the mouth. They will look for irregularities on all sides of the tongue and underneath. The dentists or hygienists will feel tissues in the mouth and neck for lumps or abnormalities. Early detection from an oral cancer screening could lead to follow up care and testing.
