The voice box, medically known as the larynx, is an essential structure located in the throat. It plays a crucial role in breathing, speaking, and protecting the airway during swallowing. Tumours that develop in the voice box can be benign (non-cancerous) or malignant (cancerous), with laryngeal cancer being the most serious form. Voice box tumours often arise from the cells lining the larynx, and they can significantly affect speech and breathing if not diagnosed and treated promptly.
Voice box tumours typically originate in the squamous cells that line the larynx. These tumours are most often seen in individuals over 50 years of age and are more common in men, although changing lifestyle patterns have led to increasing cases among women. The primary cause of laryngeal cancer is long-term exposure to tobacco smoke, though excessive alcohol consumption, poor nutrition, and infection with human papillomavirus (HPV) are also contributing factors.
Benign tumours such as polyps, nodules, and papillomas can also occur in the voice box. While not life-threatening, these growths can still affect vocal function and quality of life, particularly for individuals who use their voice professionally, such as singers or teachers.
The signs and symptoms of voice box tumours can vary depending on the location and stage of the tumour. Common symptoms include:
Persistent hoarseness or voice change: This is often the earliest and most noticeable symptom.
Chronic sore throat or cough: Especially when it doesn't respond to typical treatment.
Difficulty swallowing (dysphagia): Feeling that food is stuck in the throat.
Ear pain: Known as referred pain, it occurs due to shared nerve pathways.
A lump or mass in the neck: Often an indicator that cancer has spread to lymph nodes.
Breathing difficulties: Caused by the tumour narrowing the airway.
Unexplained weight loss: A common symptom of many cancers, including laryngeal.
These symptoms may initially be subtle and easy to overlook, but persistent changes should not be ignored.
Though not all voice box tumours can be prevented, several lifestyle choices can significantly reduce the risk:
Avoid tobacco use: Smoking and chewing tobacco are the leading risk factors for laryngeal cancer.
Limit alcohol intake: Excessive drinking, especially in combination with tobacco use, greatly increases risk.
Maintain vocal hygiene: Stay hydrated, avoid straining the voice, and rest it when hoarse.
Eat a healthy, balanced diet: A diet rich in fruits and vegetables may help lower the risk of many cancers.
Avoid exposure to harmful chemicals: Use protective gear when working in environments with chemical fumes or dust.
Get vaccinated against HPV: Some strains of HPV are linked to throat and voice box cancers.
It is essential to seek medical advice if you notice any of the following:
Hoarseness or voice change lasting more than two weeks.
Difficulty swallowing or a sensation of a lump in the throat.
Persistent throat pain, especially if associated with earache.
Any unexplained lump in the neck.
Ongoing cough or breathing difficulty without a clear cause.
Early consultation allows for timely diagnosis through laryngoscopy, imaging tests, and biopsy if necessary. The earlier a tumour is detected, the more treatment options are available, including surgery, radiation therapy, chemotherapy, or targeted therapy.
Voice box tumours, particularly malignant ones, can have a profound impact on communication and overall health. Awareness of symptoms, early diagnosis, and lifestyle modifications play a key role in improving outcomes. Anyone experiencing persistent voice changes or throat-related symptoms should consult a healthcare professional without delay, as early intervention often leads to better prognosis and a higher chance of full recovery.
