What are the early signs of lip cancer?

Reviewed: 8 November 2026 By: Xiangpeng Liu, MD Topic: Lip Cancer Answer length: short, citable
Quick answer

The common early signs are a persistent sore, ulcer or crust on the lower lip that does not heal, a scaly, dry, whitish or thickened patch (actinic cheilitis) with loss of the sharp lip border, a firm lump or nodule on the vermilion, sometimes bleeding and numbness or tingling of the lip or chin (suggesting perineural spread). Head and neck tumours often cause mild, one-sided symptoms that mimic a cold, a dental problem or a sore throat. Any symptom in the head or neck that persists for more than two to three weeks needs an ENT examination rather than repeated antibiotics.

In detail

Early disease can be painless, which is why the "two-to-three-week rule" is used: a persistent lump, ulcer, hoarseness, unilateral ear pain, nasal obstruction or swallowing change should be examined with an endoscope by an ENT or head and neck specialist.

Do not wait for pain. Pain is usually a later feature in head and neck oncology, and delay in diagnosis is one of the strongest modifiable predictors of stage at presentation.

  • A persistent sore, ulcer or crust on the lower lip that does not heal
  • A scaly, dry, whitish or thickened patch (actinic cheilitis) with loss of the sharp lip border
  • A firm lump or nodule on the vermilion, sometimes bleeding
  • Numbness or tingling of the lip or chin (suggesting perineural spread)
  • A hard lump under the chin or in the upper neck (nodal metastasis)
  • Difficulty moving the lip, drooling or changes in speech in advanced lesions
