Oral cancer can appear in the lips, tongue, gums, cheeks, or mouth lining. The American Cancer Society notes that “early detection…significantly improves the chances of successful treatment,” yet its first signs are often subtle.
One warning sign is a sore that doesn’t heal within two weeks. The National Cancer Institute says these sores may be painless but should not be ignored. Another is white or red patches inside the mouth. Mayo Clinic explains that “leukoplakia” (white patches) and “erythroplakia” (red patches) may indicate precancerous changes.
Other early symptoms include unexplained bleeding, lumps or thickened areas, persistent numbness, difficulty swallowing, or bad breath that does not improve with hygiene. The CDC warns that growths or rough patches in the mouth require attention.
Risk factors include tobacco, heavy alcohol use, HPV infection, excessive sun exposure, poor diet, and being over 40. Regular screenings are essential, as dentists can detect early signs during exams.
In short, any sore, patch, or discomfort lasting over two weeks should be checked. Awareness and routine dental visits can make a life-saving difference.
