Oral cancer, also called mouth cancer, can develop in many areas of the mouth, including the lips, tongue, cheeks, gums, and even the roof or floor of the mouth.
The American Cancer Society stresses that early detection greatly improves treatment outcomes.
The challenge is that early signs are often subtle and easy to overlook.
This makes awareness—and routine dental visits—essential for catching problems before they progress.
One of the most common warning signs is a sore in the mouth that doesn’t heal within two weeks.
These sores may appear on the lips, gums, or inner cheeks and might not hurt at first, but they require medical attention.
Changes in tissue color are another red flag.
White patches (leukoplakia), red patches (erythroplakia), or a mix of both can indicate abnormal growth.
Persistent patches should always be checked by a dentist or doctor.
Other symptoms include unexplained bleeding, lumps or thickened areas, and rough patches in the mouth or throat.
While they are often painless in the beginning, they can grow over time. Persistent numbness, tingling, or discomfort in the lips, chin, or tongue may also signal nerve involvement.
