The goal of oral cancer screening is to detect [[mouth]] cancer or [[precancerous]] lesions that may lead to mouth cancer but no studies have proved that oral cancer screening saves lives. People with a high risk of oral cancer may be more likely to benefit from oral cancer screening. There is inadequate evidence to establish whether screening would result in a decrease in [[mortality]] from oral cancer.

Screening for oral cancer may be done during a routine check-up by a dentist or medical doctor. The exam will include looking for [[lesions]], including areas of [[leukoplakia]] (an abnormal white patch of cells) and [[erythroplakia]] (an abnormal red patch of cells). Leukoplakia and erythroplakia lesions on the mucous membranes may become cancerous.

*Toluidine blue stain: A procedure in which [[lesions]] in the mouth are coated with a blue dye. Areas that stain darker are more likely to be cancer or become cancer.
*Fluorescence staining: A procedure in which lesions in the mouth are viewed using a special light. After the patient uses a [[fluorescent]] mouth rinse, normal tissue looks different from abnormal tissue when seen under the light.
*Exfoliative [[cytology]]: A procedure to collect cells from the lip or oral cavity. A piece of cotton, a brush, or a small wooden stick is used to gently scrape cells from the lips, [[tongue]], mouth, or throat. The cells are viewed under a microscope to find out if they are abnormal.
*Brush biopsy: The removal of cells using a brush that is designed to collect cells from all layers of a [[lesion]]. The cells are viewed under a microscope to find out if they are abnormal.
More than half of oral cancers have already spread to lymph nodes or other areas by the time they are found.

Overview

There is insufficient evidence to recommend routine screening for oral cancer.

Screening

  • There is insufficient evidence to recommend routine screening for oral cancer.[1]
  • There is no country that has any routine screening program for oral cancer.
  • There is insufficient evidence to support any screening modality that might decrease mortality in oral cancer.
