What is Larynx Cancer?
Larynx cancer, also known as laryngeal cancer, is a type of cancer that affects the larynx, which is commonly referred to as the voice box. The larynx plays a crucial role in producing sound and helping us speak. Laryngeal cancer occurs when the cells in the lining of the larynx become malignant, leading to the formation of tumors.
Definition
Larynx cancer refers to the abnormal growth of cells in the larynx, specifically the vocal cords or other areas of the voice box. These cancerous cells can invade nearby tissues and spread to other parts of the body if left untreated.
Statistics
According to the American Cancer Society, laryngeal cancer is relatively uncommon compared to other types of cancer. In the United States, it is estimated that about 12,000 new cases of laryngeal cancer will be diagnosed in 2021, with approximately 3,750 deaths from the disease. Globally, larynx cancer affects both men and women, with a higher incidence in men.
Risk Factors
Several risk factors can increase the likelihood of developing larynx cancer. The most common risk factors include:
-
Tobacco use: Smoking tobacco, including cigarettes, cigars, and pipes, significantly increases the risk of larynx cancer. Chewing tobacco or using snuff is also associated with an increased risk.
-
Alcohol consumption: Heavy and long-term alcohol consumption is a risk factor for laryngeal cancer. The risk is even higher when combined with tobacco use.
-
Human papillomavirus (HPV) infection: Certain strains of HPV, a sexually transmitted infection, may increase the risk of developing laryngeal cancer.
-
Occupational exposure: Exposure to certain substances, such as asbestos, chemicals, and dust, in workplaces like construction sites or industrial settings, may increase the risk of larynx cancer.
It is important to note that while these risk factors can increase the chances of developing laryngeal cancer, not everyone who has these risk factors will develop the disease. Additionally, some individuals may develop larynx cancer without any known risk factors.
Types and Stages
Larynx cancer can be classified into different types based on the specific cells involved and the area of the voice box affected.
Squamous cell carcinoma
Squamous cell carcinoma is the most common type of laryngeal cancer, accounting for approximately 90% of cases. This type of cancer originates from the flat, thin cells lining the larynx.
Adenocarcinoma
Adenocarcinoma is a less common type of laryngeal cancer that develops from the glandular cells in the larynx.
Verrucous carcinoma
Verrucous carcinoma is a rare form of laryngeal cancer characterized by slow-growing, wart-like tumors.
Supraglottic cancer
Supraglottic cancer affects the upper portion of the larynx above the vocal cords. It includes structures such as the epiglottis and arytenoid cartilages.
Glottic cancer
Glottic cancer occurs in the vocal cords, which are situated in the middle part of the larynx. This type of cancer is more frequent in individuals who smoke.
Subglottic cancer
Subglottic cancer develops in the subglottis, which is the lower portion of the larynx just below the vocal cords. It is the least common type of laryngeal cancer.
Early-stage laryngeal cancer
Early-stage laryngeal cancer refers to cancer that has not spread beyond the larynx. It is usually easier to treat and has a higher chance of a successful recovery.
Advanced-stage laryngeal cancer
Advanced-stage laryngeal cancer indicates that the cancer has spread beyond the larynx, potentially invading nearby lymph nodes or distant organs. Treatment for advanced-stage cancer may be more challenging, but advancements in medical technology and treatment options have improved outcomes.
Causes and Prevention
Understanding the potential causes of larynx cancer can help individuals make informed decisions and take preventive measures to reduce their risk.

A persistent cough that does not improve over time could be an indication of larynx cancer. If you are experiencing continued coughing without any apparent cause, it is important to get it evaluated.
Difficulty swallowing
Difficulty or pain while swallowing, known as dysphagia, can be a symptom of laryngeal cancer. If you are having trouble swallowing or experiencing pain while eating or drinking, it is crucial to get a medical evaluation.
Ear pain
Some individuals with laryngeal cancer may experience referred pain in the ears. If you are having unexplained ear pain, it is advisable to consult a healthcare professional.
Lump in the neck
A visible or palpable lump in the neck may indicate the presence of enlarged lymph nodes due to cancer spreading from the larynx. If you notice a lump in your neck that persists for more than two weeks, it is important to have it checked by a medical professional.
Diagnosis
To diagnose larynx cancer, your healthcare provider will perform a thorough evaluation, which may include:
Biopsy
A biopsy is the definitive way to diagnose laryngeal cancer. It involves removing a small piece of tissue from the affected area of the larynx and examining it under a microscope to confirm the presence of cancerous cells.
Imaging tests
Imaging tests, such as computed tomography (CT) scans, magnetic resonance imaging (MRI), and positron emission tomography (PET) scans, may be performed to determine the size and extent of the cancer, as well as to check for the spread of the disease to other parts of the body.
Treatment Options
The treatment for larynx cancer depends on various factors, including the type and stage of cancer, overall health, and individual preferences. The primary treatment options for laryngeal cancer include:
Surgery
Surgical intervention may involve removing part or all of the larynx, depending on the stage and location of the cancer. The procedure may be performed using traditional open surgery or minimally invasive techniques, such as transoral laser microsurgery or robotic surgery.
Radiation therapy
Radiation therapy uses high-energy beams to target and kill cancer cells. It may be used as the primary treatment or in combination with surgery or chemotherapy. The aim of radiation therapy is to shrink the tumor, eradicate any remaining cancer cells, or provide palliative care to relieve symptoms and improve quality of life.
Chemotherapy
Chemotherapy involves administering drugs that kill cancer cells or inhibit their growth. It is often used in combination with surgery and/or radiation therapy to enhance the effectiveness of treatment. Chemotherapy may be given before surgery to shrink the tumor or after surgery to eliminate any remaining cancer cells.
