Head and Neck Cancer: Are Persistent Headaches a Warning Sign?

Persistent or worsening headaches can be a symptom of certain head and neck cancers, particularly cancers that involve the sinuses and nasal cavity or the nasopharynx (the area behind the nose and above the throat). ^[1] Headaches related to these cancers often come with other local signs like nasal blockage that doesn’t clear, repeated sinus infections that don’t improve with antibiotics, nosebleeds, pain or swelling around the eyes, and upper tooth pain. ^[1] In some cases, nasopharyngeal carcinoma can present with headache as the first or only symptom, so ongoing head pain without a clear cause especially if new or progressive deserves medical evaluation. ^[2]

Why Headaches Can Occur

Head and neck cancers that start in or spread to the sinus region, nasal cavity, or nasopharynx can irritate nearby nerves or increase pressure in confined spaces, leading to pain perceived as a headache. ^[1] These tumors may also cause blocked sinuses and persistent congestion, which can trigger or worsen headache patterns. ^[1] Although many headaches are benign (like tension or migraine), new, persistent, or progressively worsening headaches accompanied by nasal or ear symptoms, facial pain, or a neck lump should be checked promptly. ^{[1] [3]}

Red‑Flag Symptoms That Need Urgent Evaluation

Any symptom that lasts longer than 2–3 weeks or is steadily getting worse should prompt a medical assessment, especially in people who use tobacco or alcohol or have high‑risk viral exposures (such as HPV or EBV). ^{[4] [5]} Below are warning signs linked to head and neck cancers:

• Neck lump or swelling: A firm, persistent lump in the neck can be a cancerous lymph node. ^[6] Swollen lymph nodes in one or more areas of the neck are common in mouth and throat cancers. ^[7]
• Sore in the mouth or throat that does not heal: Persistent ulcer or sore throat beyond two weeks is concerning. ^{[6] [8]}
• Voice changes (hoarseness): Ongoing hoarseness or voice change can indicate laryngeal (voice box) cancer. ^{[6] [9]}
• Difficulty or pain with swallowing (dysphagia or odynophagia): Trouble swallowing or pain when swallowing requires evaluation. ^{[6] [9]}
• Ear pain or hearing issues: Referred ear pain without obvious ear infection may be a sign of throat or laryngeal cancer. ^{[1] [9]}
• Nasal symptoms that persist: Blocked nose that doesn’t go away, recurrent nosebleeds, or sinus infections not responding to antibiotics can signal sinus or nasal cavity cancer. ^{[1] [10]}
• White or red patches in the mouth or throat: These patches can be precancerous changes and need assessment. ^{[3] [11]}
• Unintentional weight loss: Losing weight without trying can be an “alarm” symptom. ^[10]
• Trouble breathing or stridor: Breathing difficulty or noisy breathing is urgent. ^[3]
• Facial pain, numbness, or weakness: Persistent facial discomfort or nerve changes can indicate salivary gland or other head and neck tumors. ^{[12] [3]}

Headaches Plus Specific Clusters of Signs

When headaches occur with any of the following, the concern for head and neck cancer increases:

• Headache + nasal blockage, nosebleeds, upper tooth pain, or eye pain/swelling: Suggestive of sinus or nasal cavity tumors. ^[1]
• Headache as the primary or sole symptom (especially persistent for months): Recognized presentation of nasopharyngeal carcinoma; timely diagnosis leads to better symptom relief and outcomes. ^[2]
• Headache + ear fullness, hearing loss, or recurrent ear infections without a clear cause: Can reflect nasopharyngeal involvement affecting Eustachian tube function. ^[1]
• Headache + neck mass: Could indicate regional lymph node spread and warrants urgent imaging and specialist review. ^[7]

When to Seek Care

• Seek evaluation if symptoms last longer than two weeks. Many head and neck cancer symptoms resemble common colds or sinus infections, but persistence is a key differentiator. ^[4]
• Seek urgent care if symptoms are rapidly worsening, if there is bleeding (like recurring nosebleeds or coughing up blood), or if breathing or swallowing is compromised. ^{[10] [6]}
• People at higher risk (tobacco/alcohol use; prior or known HPV/EBV exposure) should be especially cautious and not delay assessment. ^[5]

What to Expect During Evaluation

A thorough exam includes inspection of the mouth, throat, and nasal passages, palpation of the neck for lymph nodes, and evaluation of the ears. ^[13] Depending on findings, your clinician may order imaging (CT/MRI) for sinuses, nasopharynx, or neck, and endoscopy to visualize deeper areas of the throat and nasal cavity. ^[13] Biopsy of suspicious areas or lymph nodes is essential for diagnosis. ^[14]

How Head and Neck Cancer Symptoms Vary by Location

• Larynx (voice box): Hoarseness, pain when swallowing, ear pain, and neck mass from lymph nodes. ^{[1] [9]}
• Oropharynx and hypopharynx (back of the throat): Persistent sore throat, pain with swallowing, feeling of something stuck, blood in phlegm, voice changes, breathing difficulty, and neck lumps. ^[15]
• Sinuses/Nasal cavity: Persistent sinus blockage, resistant sinus infections, nosebleeds, headaches, eye pain/swelling, and upper tooth pain. ^[1]
• Salivary glands: Facial pain that doesn’t go away, swelling near jaw or under the chin, facial numbness or weakness. ^[12]
• Oral cavity (mouth): Mouth ulcers that won’t heal, bleeding, numbness, loose teeth, denture fit changes, and lumps. ^{[8] [16]}

Practical Tips

• Track symptoms: Note duration, progression, and associated signs (nosebleeds, ear pain, swallowing issues, neck lumps).
• Do not self‑treat persistent symptoms: If a “sinus infection” or “sore throat” doesn’t improve after appropriate treatment, ask for re‑evaluation. ^{[1] [4]}
• Early assessment improves outcomes: Many head and neck cancers are curable, especially when found early, and prompt treatment often relieves symptoms like headache. ^{[4] [2]}

Key Takeaways

• Yes, persistent or worsening headaches can be a symptom of head and neck cancer, especially sinus, nasal cavity, and nasopharyngeal cancers, and are more concerning when paired with nasal blockage, nosebleeds, facial pain/swelling, or a neck lump. ^{[1] [2]}
• Seek urgent evaluation for symptoms lasting beyond two weeks or rapidly worsening, particularly hoarseness, a nonhealing mouth or throat sore, difficulty or pain with swallowing, ear pain without ear disease, a persistent neck lump, nasal symptoms that don’t resolve, or unexplained weight loss. ^{[6] [10] [4]}
