Smoking cigarettes is one of the major preventable risk factors for laryngeal cancer, a type of cancer that develops in the larynx, commonly known as the voice box.
The larynx plays an important role in breathing, swallowing, and producing sound. Because cigarette smoke contains numerous toxic and cancer-causing chemicals, repeated exposure can damage cells in the tissues of the larynx and increase the likelihood of cancer developing.
How Smoking Can Damage the Larynx
When a person smokes, harmful substances in tobacco smoke pass directly through the mouth and throat and come into contact with the tissues of the upper respiratory system.
Repeated exposure can cause cellular damage and changes that may eventually contribute to the development of cancer.
The risk generally increases with the amount and duration of tobacco exposure. However, there is no completely safe level of cigarette smoking.
What Is Laryngeal Cancer?
Laryngeal cancer occurs when abnormal cells in the larynx begin growing uncontrollably.
Depending on where the cancer develops, it can affect a person’s voice, breathing, or ability to swallow.
Some possible warning signs include:
- A persistent or unexplained change in the voice or hoarseness
- A sore throat that does not go away
- Pain or difficulty when swallowing
- A lump or swelling in the neck
- Persistent coughing
- Ear pain without an obvious cause
- Difficulty breathing
- Unexplained weight loss
These symptoms can have many causes other than cancer, but persistent or worsening symptoms should be assessed by a healthcare professional.
Smoking Is a Preventable Risk Factor
One of the most important ways to reduce the risk of smoking-related disease is to avoid tobacco or quit smoking.
Stopping smoking can provide health benefits at any age. People who smoke and want to quit can speak with a doctor, pharmacist, or smoking-cessation service about available support and treatment options.
Avoiding tobacco can also reduce the risk of several other serious conditions, including cancers of the lung, mouth, throat and esophagus, as well as heart and respiratory diseases.
When Should You Seek Medical Advice?
A persistent change in your voice, unexplained difficulty swallowing, a neck lump, or other symptoms involving the throat should not be ignored—particularly if they continue for several weeks.
Having these symptoms does not necessarily mean that someone has cancer. Nevertheless, getting checked promptly can help identify the cause and, if cancer is present, allow treatment to begin as early as possible.
The Bottom Line
Cigarette smoking significantly increases the risk of laryngeal cancer. Avoiding tobacco is one of the most effective steps a person can take to lower that risk.
If you smoke, quitting can be an important investment in your long-term health. If you have persistent throat or voice symptoms, seek medical advice rather than waiting for them to disappear on their own.
