Verified By Dr. Saurabh Bansal | 13-Dec-2025

Dr. Saurabh Bansal, Consultant & Head, Department of Radiation Oncology at Kailash Hospital, Dehradun, reviews a diagnostic scan with a seasoned eye. "In my clinic, the most common and dangerous phrase I hear is, 'I thought it would go away.' Patients often endure subtle symptoms for months, dismissing them as a persistent cold or acidity. This delay is our greatest adversary in the fight against throat cancer. Recognizing the early signs is not about inducing fear; it is about empowering individuals with knowledge that can lead to a timely, and often lifesaving, diagnosis."

Throat cancer, which includes cancers of the oropharynx and larynx, can be a stealthy disease. Its early symptoms are frequently mistaken for common, benign conditions. This comprehensive guide, drawing on the extensive expertise of Dr.Saurabh Bansal and the multidisciplinary oncology team at Kailash Hospital, Dehradun, aims to demystify the symptoms and provide a clear, clinical roadmap for when to seek expert evaluation.

What Is Throat Cancer?

Throat cancer refers to malignant growths that develop in the tissues of the throat, voice box, or tonsils. It is broadly classified under head and neck cancers and is most commonly squamous cell carcinoma, arising from the flat cells lining the throat.

Depending on the location, throat cancer may involve:

• Pharyngeal cancer (nasopharynx, oropharynx, hypopharynx)
• Laryngeal cancer (voice box, vocal cords, epiglottis)
• Tonsillar cancer/Tonsillar fossa

Dr. Bansal notes, “The throat is involved in breathing, swallowing, and speech. Cancer in this region can disrupt all three, which is why symptoms often overlap and are sometimes ignored.”

Causes and Risk Factors of Throat Cancer: Understanding the Triggers

While the exact cause of any individual cancer is complex, several well-established risk factors significantly increase the likelihood of developing throat cancer. At Kailash Hospital, Dehradun, a patient's history is carefully reviewed to understand their risk profile.

Primary Modifiable Risk Factors:

• Tobacco Use: This is the single most significant risk factor. This includes smoking cigarettes, cigars, or pipes, as well as the use of smokeless tobacco products like khaini, gutka, and paan with tobacco. The carcinogens in tobacco directly damage the DNA in the cells lining the throat.
• Heavy Alcohol Consumption: Chronic, heavy alcohol use is a major independent risk factor. When combined with tobacco use, the risk multiplies—it is not just additive but synergistic, meaning the combined effect is far greater than the sum of individual risks.
• Human Papillomavirus (HPV) Infection: Infection with certain high-risk strains of HPV, particularly HPV-16, has become a leading cause of oropharyngeal cancer (tonsils, base of tongue) in younger, non-smoking individuals. This is a distinct type of throat cancer with different biological characteristics and often a better prognosis.

Other Contributing Factors:

• Poor Nutrition: A diet deficient in fruits and vegetables may increase risk.
• Gastroesophageal Reflux Disease (GERD): Chronic acid reflux, where stomach acid frequently flows back into the esophagus and throat, may irritate and damage the lining over time.
• Occupational Exposures: Exposure to certain substances like asbestos, wood dust, or chemical fumes in certain industries.
• Genetic Factors: While less common, a family history of head and neck cancers can play a role.

Dr.Saurabh Bansal emphasizes, "Understanding these risk factors is crucial for prevention. In our consultations, we don't just diagnose; we counsel. For many patients, addressing tobacco and alcohol use is the most powerful step they can take to prevent recurrence or a new primary cancer after treatment."

Decoding the Symptoms: From Common Complaint to Critical Concern

The early signs of throat cancer can be subtle and nonspecific. It is the persistence, progression, and combination of these symptoms that raise a red flag. Here are the key clinical indicators that warrant professional investigation.

1. The Persistent Sore Throat: A Duration That Demands Attention

A sore throat is universal, but its timeline is diagnostic.

• The Red Flag: A sore throat for 3 months or longer that does not resolve with standard treatments for allergies, reflux, or infection.
• Clinical Insight: "While a viral or bacterial infection typically resolves within two weeks, a malignancy causes persistent irritation and ulceration," explains Dr. Bansal. "When a patient presents with a chronic sore throat without an obvious infectious cause, it immediately prompts us to look deeper. This is the most frequent entry point to a diagnosis."

2. Hoarseness or a Change in Voice: The Vocal Cord's Distress Signal

The larynx, or voice box, is a common site for throat cancer.

• The Red Flag: Hoarseness or a noticeable change in voice quality—such as raspiness, weakness, or lower pitch—that persists for more than two weeks without a clear link to a respiratory infection or vocal strain.
• Clinical Insight: "For cancers affecting the glottis (vocal cords), hoarseness is often the very first sign of cancer of the throat. The tumor interferes with the smooth vibration of the cords, altering the voice at an early stage," notes Dr. Bansal.

3. Difficulty or Pain When Swallowing (Dysphagia/Odynophagia)

Swallowing is a complex mechanism easily disrupted by a growing mass.

• The Red Flag: A sensation of food "sticking" in the throat, persistent pain during swallowing, or a feeling of a lump (globus sensation). The pain may radiate to the ear on the same side, known as referred otalgia.
• Clinical Insight: This often indicates a tumor inside throat that is physically obstructing the pathway or causing ulceration in the mucosal lining.

5. A Lump in the Neck: The Telltale Node

This is often the first physically palpable sign.

• The Red Flag: A new, painless lump or swelling in the neck, typically firm and fixed to deeper tissues. This is usually an enlarged lymph node indicating that the body's immune system is responding to the cancer.
• Clinical Insight: "Not all neck lumps are cancerous, but a unilateral, non-tender, progressively enlarging node in an adult, especially when combined with other throat symptoms, requires immediate investigation to rule out metastasis," states Dr. Bansal.

5. Additional Supporting Symptoms

• Unexplained Weight Loss: Significant, unintentional weight loss without diet or lifestyle changes.
• Persistent Cough or Coughing Blood: A cough that doesn't resolve or the presence of blood in saliva or phlegm.
• Ear Pain: Persistent pain in one ear without signs of an ear infection.
• Chronic Bad Breath: Foul breath that is not related to dental hygiene.

The Diagnostic Pathway: From Symptom to Clarity at Kailash Hospital

If one or more of these symptoms are present, the next step is a structured medical evaluation. Self-diagnosis or prolonged observation is strongly discouraged. At Kailash Hospital, Dehradun, recognized as a leading best hospital in Dehradun, the diagnostic process is meticulous and patient-centric.

• Comprehensive Clinical Examination: An oncologist in Dehradun or an ENT surgeon will take a detailed history and perform a physical examination of the neck and oral cavity.
• Nasoendoscopy/Laryngoscopy: This is the cornerstone of diagnosis. A thin, flexible scope with a camera is passed through the nose to visualize the entire throat, larynx, and vocal cords without pain. This allows direct visualization of any tumor inside throat.
• Biopsy: If a suspicious lesion is seen, a small tissue sample is taken for pathological analysis. This is the only definitive way to confirm a cancer diagnosis.
• Imaging Studies: A CT scan, MRI, or PET-CT scan is used to determine the exact size, location, and extent (stage) of the cancer and to check for spread to lymph nodes or other organs.

Modern Treatment Modalities: A Personalized Approach at Kailash Hospital

Treatment for throat cancer is highly individualized, based on the exact location, stage, pathology (including HPV status), and the patient's overall health. At Kailash Hospital, Dehradun, a team of top oncologists in Dehradun collaborates to formulate the best plan, often combining modalities for maximum effectiveness.

The primary treatment options are:

1. Radiation Therapy

• Purpose: Uses high-energy beams (like X-rays or protons) to precisely target and destroy cancer cells.
• Advanced Techniques at Kailash Hospital: We employ Intensity-Modulated Radiation Therapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT). These technologies allow us to sculpt the radiation dose exactly to the shape of the tumor inside throat, minimizing exposure to critical nearby structures like salivary glands, the spinal cord, and healthy swallowing muscles. This precision is vital for preserving function and reducing side effects.

2. Surgery

• Purpose: To physically remove the cancerous tumor and, when necessary, affected lymph nodes in the neck (neck dissection).
• Modern Approaches: For eligible tumors, Transoral Robotic Surgery (TORS) or micro laser surgery is used. These minimally invasive techniques allow surgeons to operate through the mouth without external incisions, leading to less pain, faster recovery, and better functional outcomes in speech and swallowing compared to traditional open surgery.

3. Systemic Therapies

• Chemotherapy: Uses powerful drugs to kill cancer cells or stop their growth throughout the body. It is often given concurrently with radiation ("chemoradiation") to enhance the radiation's effectiveness, especially for advanced stages.
• Targeted Therapy: Drugs that specifically attack cancer cells based on their unique molecular markers (e.g., Cetuximab targets the EGFR protein).
• Immunotherapy: A groundbreaking approach that boosts the patient's own immune system to recognize and fight cancer cells. Drugs like Pembrolizumab are used for recurrent or metastatic disease.

Dr. Bansal explains the process: "Our weekly Multidisciplinary Tumor Board is where the plan takes shape. The surgical oncologist, radiation oncologist, medical oncologist and nuclear medicine review every scan and pathology reports together. For an early-stage vocal cord cancer, radiation or laser surgery alone might be curative. For a locally advanced HPV-positive tumor, a combination of chemotherapy and precision radiation may be the standard, aiming for cure while preserving the larynx. Our goal at Kailash Hospital, Dehradun, is always two-fold: to eradicate the cancer and to protect and to improve the patient's quality of life—their voice, their swallowing, their ability to connect with the world."
