Head & Neck Cancer Symptoms & Early Signs

Start Here

Most of the symptoms on this page turn out to have ordinary, non-cancerous causes. A neck lump is far more often an infection than a tumour. A sore throat is usually just a sore throat.

What matters is persistence. Head and neck cancers are highly treatable when found early, and the single most useful rule is this:

Any of these symptoms lasting more than three weeks should be examined by a specialist.

Three weeks is long enough for infections and irritation to settle, and short enough that early cancers remain very treatable. This page explains which symptoms matter, and why.

What Is Head and Neck Cancer?

Head and neck cancer is a group of cancers arising in the mouth, throat, voice box, nose and sinuses, and salivary glands. It does not include brain cancer or thyroid cancer, which behave differently and are managed separately.

In India, oral cavity cancer — cancer of the mouth and tongue — is the most common type, and India accounts for a large share of the world's cases. This is closely linked to chewing tobacco, gutkha, paan and areca nut.

Early Signs by Symptom

A Lump in the Neck

The most frequent first sign. Cancer of the mouth or throat often spreads first to the lymph nodes of the neck, and occasionally the neck lump appears before any other symptom.

More concerning if the lump is: painless, firm or hard, fixed rather than moving freely, growing, or present for more than three weeks in an adult.

Usually less concerning: tender, soft, rapidly appearing alongside a sore throat or dental infection, and shrinking within two to three weeks.

Neck lumps have many causes — infection, tuberculous lymphadenitis, which is common in India, and reactive lymph nodes. See neck lump — causes and when to worry for the full picture.

A Mouth Ulcer That Will Not Heal

Ordinary mouth ulcers heal within two weeks. An ulcer still present after three weeks needs examination, particularly if it is painless, has raised or irregular edges, bleeds easily, or sits on the side of the tongue.

Painlessness is often what delays diagnosis — people assume pain means serious and no pain means safe. With oral cancer, the reverse is frequently true. See non-healing mouth ulcer warning signs.

White or Red Patches in the Mouth

• Leukoplakia — a white patch that cannot be scraped off
• Erythroplakia — a red, velvety patch, less common but carrying a higher risk

Both are pre-cancerous changes, not cancer itself. Identified and monitored early, they can often be treated before any cancer develops. See white patch in the mouth.

Hoarseness or Voice Change

A voice change lasting more than three weeks warrants a laryngoscopy — a quick outpatient examination of the voice box. Laryngeal cancer often causes hoarseness early, which is why it is frequently caught at a curable stage. See hoarseness that will not go away.

Difficulty or Pain on Swallowing

Persistent difficulty swallowing, a sensation of food sticking, or pain radiating to the ear on swallowing. One-sided ear pain with a normal-looking ear is a classic referred-pain pattern from a throat tumour and is easy to dismiss. See difficulty swallowing.

Other Signs

• Persistent one-sided nasal blockage, especially with bleeding
• A lump in the cheek or below the ear — possible salivary gland tumour
• Loose teeth with no dental cause, or dentures that stop fitting
• Numbness of the lip, tongue or face
• Persistent one-sided sore throat
• Unexplained weight loss
• Coughing up blood, or blood-stained saliva

Who Is at Higher Risk?

• Tobacco in any form — smoking, and especially chewed tobacco, gutkha, paan and areca nut, which drive India's high rate of oral cancer
• Alcohol, which multiplies rather than adds to tobacco risk
• HPV infection, an increasing cause of oropharyngeal cancer, often in younger non-smokers
• Age over 40, though HPV-related cancers appear earlier
• Prior pre-cancerous lesions such as leukoplakia
• Chronic irritation from a sharp tooth or poorly fitting denture

Risk factors raise probability; they do not determine outcome. Head and neck cancer does occur in people with none of them — which is why a persistent symptom should be checked regardless of history. If you use tobacco, what it does to the ear, nose and throat is worth reading.

What Happens at Assessment

Evaluation is usually completed quickly, often within one or two visits:

1. Examination — of the mouth, throat and neck, including a flexible endoscope passed through the nose to view the throat and voice box. It takes a minute or two and requires no anaesthetic.
2. Ultrasound and FNAC — for a neck lump, ultrasound plus a fine needle sample, generally done the same day with results in a few days.
3. Biopsy — a small tissue sample from any suspicious ulcer or patch. This is what confirms or excludes cancer. See what to expect from an oral biopsy.
4. Imaging — CT or MRI if cancer is confirmed, to determine extent and plan treatment.

Most people who go through this process do not have cancer. The purpose is to settle the question quickly.

If It Is Cancer

Head and neck cancers found early are frequently curable. Treatment is planned by a multidisciplinary team and may involve:

• Surgery, including minimally invasive robotic (TORS) and laser approaches
• Neck dissection when lymph nodes are involved
• Reconstruction to restore appearance, speech and swallowing
• Radiotherapy and chemotherapy, alone or alongside surgery
• Rehabilitation — speech and swallowing therapy as part of recovery, not an afterthought

The Takeaway

Do not wait for pain. Several head and neck cancers are painless in their early stages, and waiting for a symptom to hurt is the most common reason for late diagnosis.

Three weeks is the threshold. If a lump, ulcer, patch, voice change or swallowing problem has lasted longer, have it examined. Most such examinations end in reassurance — and the ones that do not are far better caught now.

Who You Would See

Head and neck cancer is managed by a head and neck oncosurgeon — a super-speciality within ENT requiring training beyond a general ENT qualification (an MCh in Head & Neck).

At THANC, this team is led by Dr. Vidhyadharan S, MCh (Head & Neck), whose practice covers head and neck surgical oncology, microvascular reconstruction, and transoral robotic surgery (TORS). Care is planned by a multidisciplinary team, with speech and swallowing rehabilitation built into recovery.

If you are not sure whether your symptom needs this level of care, a general ENT consultation is the right starting point — you will be referred internally if further expertise is needed.
