What are the early signs of nasopharyngeal carcinoma?

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

The common early signs are a painless lump in the upper neck (the most common presenting sign), unilateral nasal obstruction, discharge or nosebleeds, one-sided middle-ear effusion, muffled hearing, tinnitus or a blocked-ear sensation in an adult and persistent headache, facial numbness or double vision from skull-base involvement. 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 painless lump in the upper neck (the most common presenting sign)
  • Unilateral nasal obstruction, discharge or nosebleeds
  • One-sided middle-ear effusion, muffled hearing, tinnitus or a blocked-ear sensation in an adult
  • Persistent headache, facial numbness or double vision from skull-base involvement
  • Sore throat, changes in voice, or difficulty opening the mouth in advanced disease
  • Unexplained weight loss; rarely, cranial nerve palsies affecting eye movement
