Oral cancer screening is a process of examining the mouth and throat for signs of cancerous or precancerous conditions. This can include a visual examination of the mouth, throat, and neck, as well as various diagnostic tests such as biopsies or imaging scans. Early detection of oral cancer is important for successful treatment and improved outcomes. Screening for oral cancer is typically recommended for individuals who are at higher risk, such as smokers, heavy drinkers, or those with a family history of oral cancer.
