Section 01
What is Head & Neck Cancer?
Head and neck cancer is a broad term for cancers that begin in the mouth, throat, voice box, sinuses, salivary glands, or the upper part of the throat behind the nose. More than 90% of these cancers are squamous cell carcinomas, arising from the thin, flat cells that line these moist surfaces.
Head and neck cancer is one of the most strongly preventable cancer groups, since the overwhelming majority of cases are linked to tobacco use, alcohol consumption, or HPV infection. In India specifically, the widespread use of smokeless tobacco products such as gutkha, khaini, and betel quid has made oral cavity cancer a disproportionately large public health problem.
Section 02
Types of Head & Neck Cancer
Head and neck cancer is not a single disease. The exact site of origin significantly affects symptoms, treatment approach, and prognosis. Dr. Aditya Sarin evaluates each case individually to determine the precise site and stage.
Most Common in India
Oral Cavity Cancer
Affects the lips, tongue, gums, inner cheek lining, floor of the mouth, and hard palate. Strongly linked to smokeless tobacco and betel quid.
HPV-Linked (West)
Oropharyngeal Cancer
Affects the base of the tongue, tonsils, and soft palate. Increasingly linked to HPV in Western countries, though tobacco dominates in India.
Voice Box
Laryngeal Cancer
Strongly linked to smoking and alcohol use, often presenting with voice changes.
Often Late-Diagnosed
Hypopharyngeal Cancer
Affects the lower throat, just above the oesophagus. Often diagnosed late since early symptoms are subtle.
EBV-Linked
Nasopharyngeal Cancer
Affects the upper part of the throat behind the nose. Linked to Epstein-Barr virus infection.
Less Common
Salivary Gland Cancer
A less common group with a wider range of subtypes and generally different risk factors than tobacco-linked head and neck cancers.
Section 03
Symptoms of Head & Neck Cancer
Symptoms depend on the exact site affected, but several warning signs are common across head and neck cancers and should never be dismissed, particularly in tobacco or gutkha users.
A mouth ulcer or sore that does not heal within three weeks
A white or red patch inside the mouth
A lump or thickening in the cheek, neck, or mouth
Persistent sore throat or feeling something is stuck
Difficulty chewing, swallowing, or moving the tongue or jaw
Hoarseness or voice changes lasting more than a few weeks
Numbness in the mouth or face
Unexplained loosening of teeth or a poorly fitting denture
A persistent lump in the neck
Note: Many of these symptoms overlap with minor, non-cancerous conditions, but persistence beyond two to three weeks, especially in a tobacco or gutkha user, warrants prompt evaluation.
Section 04
Causes & Risk Factors
Head and neck cancer, and oral cavity cancer in particular, is among the most strongly preventable cancer groups, with the large majority of cases linked to identifiable, modifiable risk factors.
Smokeless Tobacco & Gutkha
Gutkha, khaini, and betel quid contain tobacco-specific nitrosamines that directly damage DNA. The leading cause of oral cancer in India.
Smoked Tobacco
Cigarettes, bidis, and other smoked tobacco significantly increase risk across all head and neck sites, particularly the larynx.
Alcohol Consumption
Alcohol independently increases risk, and combined with tobacco, multiplies risk well beyond either factor alone.
HPV Infection
HPV-16 is a growing cause of oropharyngeal cancer, especially in patients without a tobacco history.
Betel Quid & Areca Nut
Independently increases oral cancer risk and is strongly linked to oral submucous fibrosis, a precancerous condition.
Poor Oral Hygiene
Chronic irritation from ill-fitting dentures, sharp teeth, or poor oral hygiene contributes to oral cavity cancer risk.
Having one or more risk factors does not guarantee a person will develop head and neck cancer, but the combination of tobacco, alcohol, and areca nut use — common in India — substantially compounds risk.
Section 05
Head & Neck Cancer Screening & Early Detection
Unlike many internal cancers, the oral cavity is directly visible, which makes self-examination and dental or ENT checks genuinely effective tools for early detection, particularly for tobacco and gutkha users.
Self-Oral Examination
Regularly check the mouth, tongue, and inner cheeks for ulcers, patches, or lumps that do not resolve within three weeks.
Dental or ENT Examination
Routine dental visits often detect early, asymptomatic lesions before patients notice them.
Biopsy
A tissue sample from any suspicious ulcer, patch, or lump is required to confirm a cancer diagnosis.
Imaging
CT, MRI, or PET-CT scans assess the extent of the tumour and whether it has spread to lymph nodes or beyond.
There is no blood test or population-wide screening programme for head and neck cancer. Because the oral cavity is visually accessible, community-based visual screening programmes are among the most effective tools available for early detection in India.
Section 06
Staging of Head & Neck Cancer
Staging describes how far the cancer has spread and directly determines the treatment approach. Most head and neck cancers are staged using the AJCC TNM system, based on tumour size, lymph node involvement, and distant spread. Oropharyngeal cancer has a separate staging system depending on HPV (p16) status. This staging guidance is current as of 2026.
Stage
What it means
Stage I
A small tumour with no lymph node involvement.
Stage II
A larger tumour, still with no lymph node involvement.
Stage III
A tumour with limited spread to a single nearby lymph node, or a larger tumour without node involvement.
Stage IV
Locally advanced disease with more extensive lymph node involvement, spread to nearby structures, or distant metastasis.
Lymph node involvement significantly worsens prognosis at any tumour size, which is why a persistent neck lump should never be dismissed, particularly in a tobacco or gutkha user.
Survival statistics are population averages. They describe outcomes across large groups of patients and do not predict what will happen to any individual patient.

Treatment is tailored to the exact site, stage, and, where relevant, HPV status. Dr. Aditya Sarin develops a comprehensive, personalised treatment plan for every patient, working within a multidisciplinary team.
Surgery
Removal of the tumour and, where needed, affected lymph nodes, often the primary treatment for oral cavity cancer.
Radiation Therapy
Used alone for early-stage disease or combined with other treatments for more advanced cancers.
Chemotherapy
Often combined with radiation for locally advanced disease, or used for cancer that has spread.
Immunotherapy
Checkpoint inhibitors, now used both around the time of surgery for resectable disease and for recurrent or metastatic disease.
Targeted Therapy
Drugs that act on specific molecular features of the tumour, used in select advanced cases.
Reconstructive Surgery
Often performed alongside tumour removal to restore function and appearance, particularly for larger oral cavity resections.
Speech & Swallowing Therapy
An essential part of recovery for many patients, particularly after laryngeal or oral cavity surgery.
Tobacco Cessation Support
A critical part of treatment, since continued tobacco use after diagnosis worsens both treatment response and risk of a second cancer.

Latest Advances in Head & Neck Cancer Treatment
Head and neck cancer treatment has changed meaningfully over the past year, particularly with immunotherapy moving earlier into the treatment course. As of 2026, notable developments include the following.
1
FDA Approval · June 12, 2025 · Perioperative
Immunotherapy before and after surgery
On June 12, 2025, the FDA approved pembrolizumab as a perioperative treatment — before and after surgery — for adults with resectable, locally advanced head and neck squamous cell carcinoma whose tumours express PD-L1. This was the first new approval for this cancer type in six years and the first perioperative immunotherapy approval for locally advanced disease, based on the Phase 3 KEYNOTE-689 trial, which showed a significant improvement in event-free survival.
FDA Approval · Early 2026 · Nasopharyngeal Carcinoma
A new frontline option for nasopharyngeal carcinoma
In early 2026, the FDA approved penpulimab in combination with cisplatin or carboplatin and gemcitabine for the first-line treatment of adults with recurrent or metastatic nonkeratinizing nasopharyngeal carcinoma, expanding immunotherapy options for this specific head and neck cancer subtype.
Whether either of these developments applies to a given patient depends on tumour site, PD-L1 or HPV status, and disease stage, and should be discussed directly with an oncologist.
Section 10
Living with Head & Neck Cancer
A head and neck cancer diagnosis affects eating, speaking, and appearance in ways that few other cancers do, making comprehensive support an integral part of treatment at every stage.
Speech & Swallowing Rehabilitation
Specialised therapy to restore or adapt speech and swallowing function after surgery or radiation.
Nutrition Support
Dietary guidance to manage eating difficulties during and after treatment, which are common with this cancer type.
Counselling & Support Groups
Professional emotional support and peer groups for patients and families, given the visible and functional impact of this cancer.
Section 11
Why Early Detection Matters
The mouth is one of the few places in the body a patient can actually see for themselves. In our tobacco- and gutkha-using population, that self-check can be the difference between a Stage I cure and a Stage IV fight.
— Dr. Aditya Sarin, Medical Oncologist
Localised oral cavity and pharynx cancer has an 87% 5-year survival rate, compared with 39% for distant-stage disease.
Nearly half of oral cancer cases in India are still diagnosed at a later stage, despite the mouth being directly visible.
A mouth ulcer, white patch, or lump that does not resolve within three weeks should always be checked.
A persistent lump in the neck should never be dismissed as a minor swelling.
Quitting tobacco and gutkha, even after years of use, meaningfully reduces future risk and improves treatment outcomes.

Frequently Asked Questions about Head & Neck Cancer
What is the first sign of oral cancer?
A mouth ulcer or white or red patch that does not heal within three weeks is one of the most common early signs, along with a persistent lump in the cheek, mouth, or neck.
Why is oral cancer so common in India?
Widespread use of smokeless tobacco products such as gutkha, khaini, and betel quid, often combined with poor awareness of early warning signs, makes oral cavity cancer disproportionately common in India compared with most other countries.
Can oral cancer be cured?
When caught at an early stage, oral cavity and pharynx cancer has a survival rate as high as 87 to 90 percent. Outcomes drop substantially once the cancer has spread to lymph nodes or distant sites, which is why early detection matters enormously for this cancer.
Does quitting gutkha or tobacco help after a diagnosis?
Yes. Continuing to use tobacco or gutkha after a head and neck cancer diagnosis worsens treatment response, increases complication risk, and raises the risk of a second cancer. Quitting at any stage improves outcomes.
Is HPV a cause of head and neck cancer?
Yes, particularly for oropharyngeal cancer. HPV-related cases are more common in Western countries, though tobacco and smokeless tobacco remain the dominant cause of head and neck cancer in India.
What is the difference between a mouth ulcer and oral cancer?
Most mouth ulcers heal within one to two weeks and have an identifiable cause, such as minor trauma. An ulcer, patch, or lump that persists beyond three weeks, especially in a tobacco or gutkha user, should be evaluated by a doctor.
