The image below illustrates the different parts that get affected by head and neck cancers.
The below pictures depict (a) the anatomy of a larynx and (b) what a laryngeal cancer looks like.
The type of head and neck cancer begins in the tissues of the hypopharynx. Hypopharyngeal cancer is likely to grow and spread to many different parts including cartilage around the thyroid and trachea, bone under the tongue (hyoid bone), the trachea, the thyroid, and the esophagus. The cancer may also metastasise to the lymph nodes in the neck, the carotid artery, various tissues around the upper part of the spinal column, tissues lining the chest cavity and various other parts of the body.
