  • a lump or growth on the lips, in the mouth or on the tongue
  • thickening of the inner cheek lining (the buccal mucosa)
  • bleeding in the mouth
  • earache that doesn’t go away
  • loose teeth
  • dentures that no longer fit
  • slurred speech
  • swollen salivary glands
  • swollen lymph nodes in the neck (called cervical lymph nodes)
