The pharynx, or throat, is divided into the nasopharynx, oropharynx, and hypopharynx, which is the lowest portion. Hypopharyngeal cancer is a type of cancer that occurs when the cells of the hypopharynx become abnormal and start to grow and divide more quickly than cells in healthy, normal tissue. This abnormal growth usually involves squamous cells, although other cells may be implicated.

Your pharynx is typically divided into three sections- the nasopharynx (top), oropharynx (middle), and hypopharynx (bottom). The hypopharynx is the beginning of the swallowing passage, wrapping around the voice box, and connects to the esophagus.
Hypopharyngeal cancer is a disease in which cancerous cells are found in the tissues of the hypopharynx.
