What are the early signs of laryngeal cancer?

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

The common early signs are hoarseness or a change in voice lasting more than 2–3 weeks (classic for glottic cancer), persistent sore throat, pain on swallowing or pain referred to one ear, a lump in the neck (more typical of supraglottic tumours) and difficulty swallowing, choking or coughing when eating. 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.

  • Hoarseness or a change in voice lasting more than 2–3 weeks (classic for glottic cancer)
  • Persistent sore throat, pain on swallowing or pain referred to one ear
  • A lump in the neck (more typical of supraglottic tumours)
  • Difficulty swallowing, choking or coughing when eating
  • Coughing up blood, noisy breathing (stridor) or progressive breathlessness in advanced disease
  • Unexplained weight loss and reduced exercise tolerance
