Oral cancer can affect various parts of the mouth, including the lips, tongue, cheeks, gums, and other areas. Early detection is crucial for successful treatment, but initial symptoms are often subtle and easy to overlook.

One of the main warning signs is a sore that does not heal within two weeks. These sores can appear on the lips, gums, or the inner lining of the mouth and might not cause pain at first, making them easy to ignore.

Changes in color are another important symptom. White patches, called leukoplakia, or red patches, known as erythroplakia, may indicate abnormal cell growth. Red patches are especially concerning because they are more likely to be cancerous. Additionally, persistent bleeding in the mouth without an obvious injury should raise concern.

Other signs include lumps or thickened, rough areas inside the mouth. Persistent numbness or pain in the lips, tongue, or chin should never be ignored, as these sensory changes can signal oral cancer. Difficulty chewing, swallowing, or moving the jaw may also be warning signs.

According to health experts like the National Cancer Institute, Mayo Clinic, and the American Dental Association, recognizing these early symptoms and seeking medical advice promptly can greatly improve outcomes.

Being aware of these signs and regularly checking your mouth can help catch oral cancer early, increasing the chances of successful treatment and reducing the risk of serious complications.
