Oral cancer screenings are preventive examinations that help detect early signs of cancer or abnormal tissue changes in the mouth. Early detection is extremely important because it significantly improves the chances of successful treatment and recovery. During an oral cancer screening, the dentist carefully examines the mouth, lips, tongue, throat, and surrounding tissues for unusual lumps, sores, discoloration, or other abnormalities.

The screening is quick, painless, and usually performed during a routine dental checkup. Dentists visually inspect the oral tissues and may gently feel the neck, jaw, and throat areas to check for swelling or unusual growths. In some cases, specialized lights or screening tools may be used to identify abnormal cells that may not be easily visible to the naked eye.
