5 Warning Signs of Oral Can.cer You Should Never Ignore

Occasional mouth ulcers are common, especially after accidentally biting your cheek or eating spicy foods. However, a sore that remains for more than two weeks without healing should never be ignored.

These ulcers may appear on the lips, gums, tongue, or inner cheeks. They can gradually become larger, more painful, or begin to bleed.

2. White or Red Patches Inside the Mouth

White patches (leukoplakia) or bright red patches (erythroplakia) inside the mouth can sometimes indicate abnormal cell changes.

Although these patches are not always can.cerous, they should be evaluated by a healthcare professional—especially if they persist or continue to grow.

3. Lumps or Thickened Areas

A persistent lump inside the mouth, on the gums, under the tongue, or at the back of the throat may indicate abnormal tissue growth.

Some people describe the feeling as though something is constantly stuck in the mouth or throat.
