The Hidden Danger to Your Voice Box
For decades, millions of workers unknowingly inhaled deadly asbestos fibers in shipyards, construction sites, manufacturing plants, and other industrial settings. These microscopic fibers, once lodged in the larynx, can trigger a cascade of cellular damage that eventually leads to cancer development—often decades after the initial exposure.
This comprehensive guide will explore the scientifically-proven connection between asbestos exposure and laryngeal cancer, help you recognize the warning signs, understand treatment options, and learn about the legal and financial support available to those affected by this preventable disease.
Understanding Laryngeal Cancer
Laryngeal cancer affects your larynx, part of your throat that helps you speak, breathe and swallow
What is Laryngeal Cancer?
The larynx, commonly known as the voice box or Adam's apple, is above the trachea and below the pharynx. It contains your vocal cords, which vibrate and make sound when air is directed against them.
Most laryngeal cancers form in squamous cells, the thin, flat cells lining the inside of the larynx. Laryngeal cancer is a type of head and neck cancer that accounts for one-third of all head and neck cancers.
More than one in three laryngeal cancers start here
More than half of laryngeal cancers start here, where your vocal cords are located

Current Statistics and Survival Rates
Incidence and Demographics
- In 2025, it is estimated that there will be 13,020 new cases of laryngeal cancer and an estimated 3,910 people will die of this disease
- Most people diagnosed with laryngeal cancer are 55 or older; the average age of people diagnosed is about 66
- Men are about five times more likely to develop this cancer, possibly because smoking and heavy alcohol consumption happen more among this group
- Laryngeal cancer represents 0.6% of all new cancer cases in the U.S.
Survival Rates
Early-stage laryngeal cancer is usually highly curable with surgical or radiation monotherapy, often preserving the larynx.
The Scientific Connection: How Asbestos Causes Laryngeal Cancer
Extensive research confirms that asbestos exposure increases laryngeal cancer risk by approximately 40%
Established Medical Evidence
Key Research Findings
- A 2006 report sponsored by the National Institutes of Health confirmed the connection between asbestos and laryngeal cancer
- Research shows asbestos exposure increases the risk of laryngeal cancer around 40%, with highly exposed workers having more than double the chance
- A significant 2016 meta-analysis revealed significantly increased SMR for laryngeal cancer (SMR = 1.69, 95% CI = 1.45-1.97) when subjects were exposed to asbestos
International Recognition
- EPA officials in March 2024 announced "a ban of ongoing uses of chrysotile asbestos to protect people from lung cancer, mesothelioma, ovarian cancer, laryngeal cancer"
- A comprehensive analysis published in March 2024 reported that asbestos fibers "have local carcinogenic effects on target organs (lungs, larynx, ovaries)"
- Researchers discovered in 2021 that 50% of workers with a history of occupational asbestos exposure had asbestos fibers near their tumor sites
The Biological Mechanism
Fiber Inhalation
Inhaled asbestos fibers can lodge in your voice box as they pass through your windpipe (trachea) on the way to your lungs
Chronic Inflammation
When asbestos fibers are inhaled, they can become lodged in the mucous membranes lining the respiratory tract, including the larynx
Immune Response
The presence of these fibers triggers a chronic inflammatory response as the body's immune system attempts to eliminate the foreign material
DNA Damage
This prolonged inflammation can lead to cellular damage and the production of reactive oxygen species (ROS), which can cause DNA damage and mutations in the epithelial cells of the larynx
Primary Sources of Asbestos Exposure Leading to Laryngeal Cancer
Understanding where and how exposure occurs is crucial for identifying at-risk individuals
Primary Industries
- Construction and Demolition: Workers handling asbestos-containing materials during construction, renovation, or demolition projects
- Shipbuilding: Navy personnel and shipyard workers exposed to asbestos insulation and fireproofing materials
- Manufacturing: Workers in plants producing asbestos-containing products like textiles, cement, and friction materials
- Mining: Asbestos miners and millers with direct exposure to raw asbestos
Additional High-Risk Occupations
- Railroad Industry: Workers exposed to asbestos in brake shoes, gaskets, and locomotive insulation
- Power Plants: Maintenance workers handling asbestos insulation around boilers and pipes
- Automotive: Mechanics working with brake pads and clutch components containing asbestos
- Firefighting: First responders exposed during building fires and emergency responses
Case Study
Recognizing Laryngeal Cancer Symptoms
Early detection significantly improves treatment outcomes. Persistent symptoms warrant immediate medical evaluation.
Early Warning Signs
Primary Symptoms
- Hoarseness or voice changes: The most common symptom that doesn't improve after a few weeks
- Persistent sore throat: A sore throat or cough that doesn't improve
- Difficulty swallowing: Pain or trouble swallowing food or liquids
- Persistent cough: A cough that won't go away, potentially with blood
- Breathing difficulties: Trouble breathing or noisy breathing
Additional Warning Signs
- Ear pain or discomfort
- Unexplained weight loss
- Lump in the throat or neck
- Bad breath that persists despite good oral hygiene
- Voice fatigue or changes in voice quality
- • Hoarseness is usually the first and most prominent symptom
- • Voice changes are noticeable early because cancer affects the vocal cords directly
- • Sore throat that doesn't improve
- • Difficulty swallowing
- • Ear pain
- • Voice changes may occur later in the disease progression
- • Breathing difficulties
- • Noisy breathing (stridor)
- • Voice changes typically occur later
When to Seek Medical Attention
If you experience the following symptoms, especially with a history of asbestos exposure, talk to a healthcare provider immediately:
- Hoarseness lasting more than two weeks
- Any combination of the above symptoms persisting for more than a few weeks
- Difficulty breathing or swallowing
- Unexplained lump in the neck
Diagnosis and Staging
Comprehensive diagnostic process to determine the extent and stage of laryngeal cancer
Diagnostic Process
Diagnosing laryngeal cancer involves a multi-step process that typically begins with recognizing signs and symptoms. The diagnostic process begins with a detailed medical history and physical examination, including questions about occupational exposure to harmful substances like asbestos.
Physical Examination
- • Detailed medical history including exposure to risk factors
- • Physical examination of the mouth, throat, and neck for abnormalities
- • Assessment of lymph nodes for swelling
Laryngoscopy Procedures
- • Indirect laryngoscopy: Using a small mirror placed at the back of the throat to visualize the larynx
- • Direct laryngoscopy: A more detailed examination using a laryngoscope inserted through the nose or mouth to visualize the larynx
- CT scans: To assess the extent of the disease and examine surrounding structures
- MRI scans: For detailed soft tissue evaluation
- PET scan: During a PET scan, a provider injects a small, safe dose of a radioactive substance into your vein to highlight areas with cancer cells
- Biopsy: A provider removes a small piece of abnormal tissue from your larynx to examine under a microscope
- Pathological examination: A specialist called a pathologist examines the cells and looks for certain protein markers
Cancer Staging
Part of a diagnosis involves staging the cancer to determine how severe the disease is and how far the tumor has grown. Staging is crucial because it determines treatment options and has a strong influence on the length of survival.
Early-Stage Laryngeal Cancer
Stages 0, 1, and 2
The tumor is small and cancer hasn't spread beyond your larynx
Advanced Laryngeal Cancer
Stage 3
Cancer has grown larger or spread to nearby lymph nodes
Stage 4
Stage 4 laryngeal cancer means the cancer may have spread into tissue outside the larynx such as the thyroid gland or food pipe
Comprehensive Treatment Options
Treatment strategies vary significantly based on the stage and location of the cancer
Early-stage laryngeal cancer is usually highly curable with surgical or radiation monotherapy, often preserving the larynx. The goal is to eliminate cancer while preserving voice function and quality of life.
Late-stage disease requires multimodal therapy and is associated with worse outcomes, frequently necessitating more extensive treatment that may not preserve the larynx.
Treatment Outcomes and Prognosis
Stage 1 glottic cancer survival rate
5-year survival in younger patients
5-year survival in older patients
The farther that cancer spreads beyond your larynx, the harder it becomes to treat
