What are the early signs of salivary gland tumours?

Reviewed: 8 November 2026 By: Xiangpeng Liu, MD Topic: Salivary Gland Tumours Answer length: short, citable
Quick answer

The common early signs are a painless, slowly growing lump in front of or below the ear (parotid) or under the jaw, weakness or asymmetry of facial movement — a warning sign for malignant invasion, rapid growth, pain, skin fixation, ulceration or numbness and a swelling on the palate, inside the cheek or on the upper lip (minor salivary glands). 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, slowly growing lump in front of or below the ear (parotid) or under the jaw
  • Weakness or asymmetry of facial movement — a warning sign for malignant invasion
  • Rapid growth, pain, skin fixation, ulceration or numbness
  • A swelling on the palate, inside the cheek or on the upper lip (minor salivary glands)
  • Difficulty opening the mouth or swallowing with deep-lobe tumours
  • Hard lumps in the neck from nodal spread in high-grade cancers
