Mouth Ulcer Not Healing? 7 Oral Cancer Warning Signs You Must Never Ignore

• Mouth cancer involves uncontrolled growth of abnormal cells in the oral cavity, affecting lips, cheeks, gums, tongue, roof, or floor of the mouth.
• Unhealed mouth ulcers lasting over three weeks are a primary warning sign, unlike normal ulcers that heal naturally.
• Red (erythroplakia) or white (leukoplakia) patches inside the mouth can indicate pre-cancerous changes, increasing cancer risk if untreated.
• A noticeable, unusual, or hard lump inside the mouth or on the lips that gradually increases in size.
• Other critical signs include changes in voice or speech, persistent mouth pain, difficulty swallowing, and unexplained weight loss.
