What is the throat cancer?

Throat cancer is a general term that usually refers to cancer of the pharynx and/or larynx. Regions included when considering throat cancer include the nasopharynx, oropharynx, hypopharynx, glottis, supraglottis and subglottis; about half of throat cancers develop in the larynx and the other half in the pharynx. Consequently, any cancers (growth and/or spread of abnormal cells that form tumors or metastasize) that develop in these regions of the throat are considered throat cancers.

Some investigators consider throat cancers a subset of esophageal cancers. For this article, only throat cancers will be discussed. Esophageal cancers include additional potential symptoms of burning or pain (pressure) in the throat and/or chest pain since they can extend from just below the pharynx to the junction of the esophagus and stomach. Moreover, esophageal cancers may include all of the throat cancer signs, symptoms, and most diagnostic and treatment protocols discussed in this article -- particularly when they are located high in the esophagus.

Throat Cancer Symptoms and Signs

Throat cancers may not cause any symptoms if they are very small and have not spread at the time of diagnosis. Sometimes, an area of irritation or discoloration on the lining issues of the throat is the only sign of an abnormality. Depending upon the extent of spread of the cancer, other symptoms can include:

  • swelling of nearby tissues,
  • enlarged lymph nodes,
  • trouble breathing,
  • difficulty speaking,
  • neck or throat pain,
  • ear pain,
  • painful swallowing, and
  • headache.

Pain or ringing in the ears may occur in some cases. Bleeding can occur from some throat cancers.
