Laryngeal cancer (also called throat cancer or voice box cancer) develops in the larynx – the voice box in the throat. It accounts for approximately 2% of all cancers. Understanding the causes, recognising early symptoms, and knowing prevention strategies significantly improves outcomes. Early detection can lead to cure rates exceeding 80%.
The larynx is a voice box located at the top of the windpipe (trachea). It contains vocal cords that vibrate to produce sound. Cancer develops when cells in the larynx become malignant and grow uncontrollably.
Key Facts About Laryngeal Cancer
- Approximately 13,500 new cases diagnosed annually in India
- 4-5 times more common in men than women
- Average age at diagnosis: 65-70 years
- Strongly associated with smoking (85-90% of cases)
- Alcohol consumption increases risk 3-5x
- 5-year survival (early stage): 80-95%
- 5-year survival (advanced stage): 30-50%
Laryngeal Cancer: Causes & Risk Factors
Modifiable Risk Factors (Can Be Reduced):
- Smoking: Biggest single risk factor – 85-90% of cases. Risk increases with duration and cigarette quantity.
- Alcohol consumption: 3-5x increased risk. Combined smoking + alcohol = synergistic (multiplicative) risk.
- Occupational exposure: Asbestos, formaldehyde, mustard gas, HPV exposure
- Chronic reflux/GERD: Stomach acid exposure to larynx increases risk
- Poor diet: Low in fruits and vegetables
Non-Modifiable Risk Factors:
- Age: Risk increases with age (most common after 60)
- Gender: Men 4-5x more likely
- HPV infection: Increases squamous cell carcinoma risk
- Family history: Slight increase if relatives had cancer
Laryngeal Cancer Symptoms: Early Warning Signs
Early detection of laryngeal cancer offers excellent prognosis. Recognise these warning signs:
Early Symptoms (Seek immediate medical attention if present for >2 weeks):
- Persistent hoarseness or voice changes: Voice sounds rough, raspy, or strained
- Persistent sore throat: Lasts more than 2 weeks, not relieved by usual remedies
- Throat pain: May feel like ear pain
- Difficulty swallowing: Feels like something is stuck in throat
- Lump in neck: Enlarged lymph nodes
Advanced Symptoms:
- Persistent cough
- Difficulty breathing
- Coughing or spitting blood
- Weight loss without dieting
How to Avoid Laryngeal Cancer: Prevention Strategies
1. Stop Smoking – The Single Most Important Step
Smoking causes 85-90% of laryngeal cancers. Quitting at any age significantly reduces risk. Risk decreases by 50% within 5 years of quitting.
2. Limit Alcohol Consumption
Heavy alcohol use (3+ drinks daily) increases risk. The combination of smoking AND alcohol has multiplicative risk. Limit to 1-2 drinks daily maximum.
3. Avoid Occupational Exposures
If your occupation exposes you to asbestos, formaldehyde, or other chemicals, use appropriate protective equipment and follow safety protocols.
4. Manage Acid Reflux (GERD)
Chronic stomach acid exposure to the larynx increases cancer risk. If you experience frequent heartburn, consult a doctor.
5. Eat a Healthy Diet
A diet rich in fruits and vegetables (containing antioxidants) may help reduce cancer risk. Limit processed meats.
6. Practice Safe Sex
HPV (human papillomavirus) increases laryngeal cancer risk. Safe sex practices reduce HPV exposure.
Diagnosis & Treatment
How Laryngeal Cancer Is Diagnosed:
- ENT examination with laryngoscopy (direct visualisation)
- Biopsy of suspicious tissue
- CT or MRI imaging to determine stage
- PET scan to check for metastasis
Treatment Options:
- Radiation Therapy: Often first-line for early-stage disease
- Surgery: Endoscopic laser removal or partial laryngectomy
- Chemotherapy: For advanced stages
- Immunotherapy: Newer option for recurrent/metastatic disease

Frequently Asked Questions
Laryngeal Cancer
Is Laryngeal Cancer Curable?
Early-stage laryngeal cancer has excellent cure rates (80-95% 5-year survival). Advanced stages are more challenging but treatment can still control disease and extend survival.
What Is The Difference Between Laryngeal And Throat Cancer?
Laryngeal cancer specifically refers to cancer of the larynx (voice box). 'Throat cancer' is a broader term that can refer to pharyngeal cancer (other parts of the throat). They are related but distinct conditions.
How Can I Prevent Laryngeal Cancer?
Stop smoking, limit alcohol, avoid occupational hazards, manage GERD, eat a healthy diet, and practice safe sex. These are the most effective prevention strategies.
What Does Hoarseness From Cancer Feel Like?
Cancer-related hoarseness is persistent (lasting >2 weeks), progressive (worsening over time), and not relieved by rest or usual remedies. It may sound rough, raspy, or strained. Any persistent voice change warrants ENT evaluation.
