Throat cancer is cancer that develops in a person’s throat. Signs of throat cancer include vocal changes, difficulty swallowing and breathing, and a lump on the neck.There are two main types of throat cancer: pharyngeal cancer and laryngeal cancer.Pharyngeal cancer develops in the pharynx, which is the part of the throat that sits behind the mouth and nasal cavity. Laryngeal cancer develops in the voice box, or larynx. The larynx is a tubular structure that sits at the top of the windpipe.Throat cancer is uncommon in the United States. In fact, according to the National Cancer Institute, pharyngeal cancers — along with oral cancer — account for around 3% of all cancer diagnoses. Laryngeal cancer accounts for around 0.7% of all cancer diagnoses.Keep reading for more information on the symptoms, signs, and causes of throat cancer.

A laryngoscope is an instrument that allows a doctor to see inside a person’s throat in order to identify any abnormalities.During a laryngoscopy, the doctor may take a biopsy of the throat tissue. They will then send the tissue sample to a laboratory technician, who will examine it for signs of cancer.There are three types of biopsy:a conventional biopsy, which involves cutting away a piece of the tissuean endoscopic biopsy, which involves removing a piece of tissue using a flexible tube, or endoscope, inserted through the moutha fine needle aspiration, which uses a needle to extract cells from a tumorCancer stagingIf the biopsy returns a positive result for throat cancer, the doctor assigns it a stage that indicates how advanced the cancer is.The five stages of throat cancer are:Stage 0: Abnormal cells are present within the lining of the throat.Stage 1: A tumor is present and measures 2 centimeters (cm) or less. It has not spread to a lymph node.Stage 2: The tumor is 2–4 cm. It has not spread to a lymph node.Stage 3: The tumor is larger than 4 cm or has spread to a lymph node on the same side of the neck. If the cancer has spread to a lymph node, it is smaller than 3 cm.Stage 4: The cancer has spread to several lymph nodes or other tissues and organs within the body.Throat cancer is a rare type of cancer that develops in a small percentage of people each year.Although symptoms can vary, they may include vocal changes, difficulty swallowing, a lump on the neck, and difficulty breathing.A person may wish to contact a doctor if they experience any symptoms of throat cancer for longer than 3 weeks.
