Discover the essentials of neck masses and what ENT exams reveal about growths in your neck. Learn more in our informative blog post.
An ENT doctor plays a crucial role in evaluating neck masses, aiming to determine if they are benign or linked to serious cancers. A thorough physical examination and detailed health history are essential first steps. The doctor may check areas such as the sternocleidomastoid muscle, tongue base, oral cavity, and neck sides. Ultrasound, magnetic resonance, and blood count tests may narrow the differential diagnosis. A fine needle aspiration biopsy or open biopsy may follow for clearer results. Possible causes include bacterial infections, dental infections, upper respiratory infections, or congenital anomalies. Risk factors for cancers include smoking, tobacco use, poor oral hygiene, HIV infection, and HPV. Symptoms like night sweats, sore throat, or nasal congestion can help identify the possible cause.
Common Causes of Neck Masses
Neck masses can come from many things. Some are not harmful and do not need treatment.
- Infections: Swollen lymph nodes most often happen because of a bacterial or viral infection.
- Thyroid Nodules: Growths in the thyroid gland can feel like lumps in the front part of the neck.
- Salivary Gland Disorders: If the salivary glands are blocked or have an infection, it can cause swelling and can feel uncomfortable or even hurt.
- Congenital Cysts: A congenital cyst is a fluid-filled sac that is there from birth.
- Tumours: A neck lump could come from a tumour. Some tumours are not cancer, but some can be.
How does palpation help identify the mass?
Palpation reveals the consistency, mobility, and tenderness of the lump.
| Characteristic | Clinical Implication |
|---|---|
| Soft and movable | Likely reactive lymph node due to infection |
| Hard and fixed | Possible malignancy or invasive growth |
| Tender to touch | Suggests inflammation or infection |
| Rubbery texture | May indicate lymphoma or chronic inflammation |
Nasopharyngoscopy and Imaging
An ENT specialist may perform a nasopharyngoscopy to identify potential neck cancer, thyroid cancer, or squamous cell carcinoma in deep neck regions. Advanced imaging techniques like ultrasound, CT scans, or MRI can provide a detailed view of the mass’s size, internal structure, and relationship to nearby areas. Imaging is especially important when assessing for salivary gland cancer, lung cancer, or head and neck cancers, especially in adults with a history of smoking, alcohol use, iodine deficiency, or HPV. Other potential diagnoses include congenital masses like thyroglossal duct cysts, branchial cleft cysts, or dermoid cysts. A thorough medical history, complete blood count, and imaging results can help determine appropriate treatment options, including surgical excision if malignancy or obstruction is suspected.
What is fine needle aspiration (FNA) biopsy?
FNA biopsy extracts cells from the neck mass to check for malignancy.
- Performed using a thin, hollow needle
- Minimally invasive and typically done in-office
- Evaluates cytology (cell appearance under microscope)
When is cancer suspected in a neck mass?
ENTs consider malignancy if the mass is painless, hard, fixed, and present for over 2 weeks.
Key warning signs include:
Non-tender lymphadenopathyns, evaluating acid reflux, or ruling out other hidden causes.
Unexplained weight loss
Persistent hoarseness
Difficulty swallowing
