Pharyngeal cancer

Last updated: March 16, 2021

Summarytoggle arrow icon

Pharyngeal cancers include all malignant tumors arising in the nasopharynx, oropharynx, or hypopharynx. These cancers are most commonly squamous cell carcinomas. Alcohol and tobacco use are the two most important risk factors and are responsible for the majority of cases. Other risk factors include certain viral infections, poor oral hygiene, and workplace-related exposures, such as radiation. The clinical presentation depends on the location of the tumor. Symptoms may include a growing cervical lump, persistent sore throat, dysphagia, or a change in the voice. Diagnosis is confirmed based on tissue biopsy, whereas the extent of spread is determined via imaging modalities like CT or MRI. Treatment usually requires a combination of surgery, radiation therapy, and chemotherapy.
