Oral cancer, also known as mouth cancer, can develop in various parts of the mouth, including the lips, tongue, cheeks, gums, and the roof or floor of the mouth. According to the American Cancer Society, early detection of oral cancer significantly improves the chances of successful treatment. Unfortunately, the initial signs are often subtle and easy to overlook, making awareness crucial for early intervention.

1. Persistent Sores That Don’t Heal

A mouth sore that does not heal within two weeks is one of the most common early signs of oral cancer. According to the National Cancer Institute, these sores may occur on the lips, gums, or inner lining of the mouth. Initially, they might not cause pain, but they should not be ignored, especially if they persist without clear cause.

What to do: Any sore that lasts longer than two weeks without signs of healing should be evaluated by a dentist or doctor.
