Question 1

What is Head and neck cancer?

Accepted Answer

Head and neck cancer refers to a broad category of malignant tumours that develop in the mucosal surfaces, glands, or soft tissues of the head and neck region, most commonly of squamous cell origin. The specific site, cell type, and extent of disease are critical factors that guide all subsequent decisions about care.

Question 2

What are the symptoms and health risks of Head and neck cancer?

Accepted Answer

Common warning signs include a persistent sore throat or hoarseness, difficulty or pain when swallowing, a lump or swelling in the neck that does not resolve, unexplained weight loss, a non-healing sore in the mouth, changes in voice quality, or unilateral ear pain and hearing loss. Depending on the tumour location, patients may also experience nasal obstruction, nosebleeds, or facial numbness. These symptoms can overlap with many benign conditions, so their presence alone does not establish a cancer diagnosis and a formal clinical evaluation is always required.

Question 3

How is Head and neck cancer diagnosed?

Accepted Answer

Diagnosis typically begins with a detailed history and a physical examination that includes flexible nasopharyngolaryngoscopy to visualise the upper airway and mucosal surfaces directly. Imaging studies — most commonly contrast-enhanced CT, MRI, and PET-CT — are used to define the extent of the primary tumour and to identify lymph node involvement or distant metastases. A tissue biopsy (which may be taken endoscopically or via fine-needle aspiration of a neck node) is necessary for histological confirmation, and tumours are staged using the AJCC/TNM system (Stage I–IV), with HPV or EBV status also recorded where relevant, as this influences prognosis and treatment planning.

Question 4

How is Head and neck cancer treated?

Accepted Answer

Treatment is highly individualised and depends on the tumour site, histological type, TNM stage, HPV/EBV status, and the patient's overall health and functional priorities. Early-stage disease (Stage I–II) may be managed with surgery alone, or with definitive radiation therapy alone, while locally advanced disease (Stage III–IVB) typically requires combined-modality treatment such as concurrent chemoradiation — often delivered using Intensity-Modulated Radiation Therapy (IMRT) and Image-Guided Radiation Therapy (IGRT) to maximise precision and reduce dose to surrounding structures. The appropriate combination and sequence of treatments is determined through individual assessment by a qualified specialist team.

Question 5

Can Head and neck cancer be treated without a procedure?

Accepted Answer

Non-surgical pathways are a well-established and often preferred option for many head and neck cancers, particularly those of the oropharynx, nasopharynx, and larynx, where organ preservation is a clinical priority. Definitive chemoradiation using advanced techniques such as IMRT and IGRT can achieve disease control comparable to surgery for appropriately selected patients while preserving swallowing and speech function. Systemic therapies including platinum-based chemotherapy, targeted agents such as cetuximab, and — in recurrent or metastatic disease — immune checkpoint inhibitors may also be incorporated into the treatment plan based on individual clinical assessment.

Question 6

When is Intensity-Modulated Radiation Therapy (IMRT) considered for Head and neck cancer?

Accepted Answer

Intensity-Modulated Radiation Therapy (IMRT) may be considered only when it is appropriate for the confirmed diagnosis and the expected benefit outweighs the individual risks. The decision may depend on symptom severity, investigation results, previous treatment, overall health and the patient's goals. A specialist should discuss alternatives and recovery before any procedure is planned.

Question 7

Which doctor treats Head and neck cancer?

Accepted Answer

Head and neck cancers are evaluated and managed by a multidisciplinary team that typically includes a head and neck surgical oncologist (or otolaryngologist with oncology subspecialty training), a radiation oncologist, and a medical oncologist. Additional specialists such as a maxillofacial surgeon, speech-language pathologist, dietitian, and dental oncologist often contribute to comprehensive care, particularly when organ-preserving or reconstructive approaches are planned.

Question 8

How do I choose a doctor for Head and neck cancer?

Accepted Answer

When comparing providers, look for a centre with a dedicated head and neck multidisciplinary tumour board, a radiation oncology team experienced in IMRT and IGRT for mucosal head and neck cancers, and clear pathways for rehabilitation support — including swallowing therapy and nutritional management — throughout and after treatment. Asking about case volume for your specific tumour site, access to HPV/EBV molecular testing, and the availability of reconstructive surgery and dental oncology services will help you make a better-informed comparison.

Question 9

What documents do international patients need to share for a medical evaluation?

Accepted Answer

Share a concise medical summary, symptom timeline, previous diagnoses, investigation and imaging reports, procedure or biopsy reports where relevant, current medicines, allergies and related treatment records. Provide clear copies with translations when needed. The reviewing doctor may request additional information before giving an opinion.

Question 10

How does GAF Healthcare help international patients plan treatment in India?

Accepted Answer

Our care coordination team can review the initial information, help identify suitable doctors and hospitals, request a medical opinion where available, explain next steps and indicative cost information, and support practical planning before travel. A remote opinion does not replace an in-person examination or emergency care.
