Laryngeal Cancer

Laryngeal cancer is a type of head and neck cancer that affects your larynx, or voice box. When not treated quickly, this type of cancer can damage your voice. It may also spread to other parts of the body.

There are three main parts of the larynx:

  • Supraglottis: the upper part of the larynx above the vocal cords, including the epiglottis— the flap that covers the trachea during swallowing so that food does not enter the lungs
  • Glottis: the middle part of the larynx where the vocal cords are located
  • Subglottis: the lower part of the larynx between the vocal cords and the trachea (windpipe)

Most laryngeal cancers form in squamous cells, the thin, flat cells lining the inside of the larynx.

Risk Factors of Laryngeal Cancer

Anything that increases your risk of getting a disease is called a risk factor. Risk factors of laryngeal cancer may include:

  • Smoking and/or chewing tobacco
  • Moderate or heavy alcohol use (more than 1 drink a day)
  • Poor nutrition
  • Human papillomavirus (HPV) exposure
  • Certain genetic mutations
  • Workplace exposures to certain fumes and chemicals
  • Gender (more common in men than women)
  • Age (more common among patients age 65 and older)
  • Race (more common among African Americans and caucasians)
  • Gastroesophageal reflux disease (GERD)

Keep in mind that having a risk factor does not mean that you will get laryngeal cancer. Likewise, not having risk factors doesn't mean that you will not get the disease. Talk with your doctor if you think you may be at risk.

Signs and Symptoms of Laryngeal Cancer

These and other signs and symptoms may be caused by laryngeal cancer or by other conditions. Check with your doctor if you have any of the following:

  • A sore throat or cough that does not go away
  • Trouble or pain when swallowing
  • Ear pain
  • A lump in the neck or throat
  • A change or hoarseness in the voice

Again, these symptoms could be related to something other than laryngeal cancer. However, should you experience any of these for more than three weeks, it is a good idea to be checked by a doctor. If it is cancer, early detection can give you better treatment results.
