C00-C14: Malignant neoplasms of lip, oral cavity and pharynx

C13: Malignant neoplasm of hypopharynx

Malignant neoplasm of the hypopharynx describes a group of cancers that originate in the hypopharyngeal region, which is part of the throat situated just above the windpipe. These types of cancers are generally associated with certain risk factors such as excessive smoking, heavy alcohol consumption, and exposure to certain toxic or irritating substances. Common symptoms include difficulty in swallowing, voice changes, ear pain, and sometimes unexplained weight loss. Malignant neoplasm of the hypopharynx tends to occur mostly in older adults, particularly those in their sixties and seventies. Like most cancers, this condition may progress from early stages whereby it affects only a small portion of the hypopharynx, to more advanced stages, where it has spread to other areas of the throat, lymph nodes, or other distant sites in the body.
