How does laryngeal cancer spread and metastasize

In recent years, laryngeal cancer has become one of the major diseases that endangers society and human health, and it has brought great pain and distress to humans. In order to reduce the incidence of laryngeal cancer, we humans should understand the spread and metastasis of laryngeal cancer:

① Direct spread: Advanced laryngeal cancer often spreads by infiltration to the submucosal membrane. Supraglottic cancer located in the epiglottis can invade the pre-epiglottic space, vallecula and tongue root forward. Arpygeal fold cancer spreads outward to the pyriform sinus and lateral wall of the hypopharynx. Glottic cancer can invade the anterior commissure forward and spread to the contralateral vocal cord; it can also destroy the thyroid cartilage forward, causing the laryngeal body to swell, and infiltrate the soft tissue of the anterior neck. Subglottic cancer spreads downward to the trachea, and can also penetrate the cricothyroid membrane to the anterior cervical muscle layer, develop to both sides, invade the thyroid gland; and affect the anterior wall of the esophagus backward.

② Lymphatic metastasis: The metastatic site is often seen in the lymph nodes at the bifurcation of the common carotid artery in the deep upper neck, and then develops along the internal jugular vein to the upper and lower lymph nodes. Subglottic cancer often metastasizes to the paraglottic lymph nodes.

③ Vascular metastasis: It can be transferred throughout the body through the blood circulation to the lungs, liver, kidneys, bones, pituitary gland, etc.

The above is the spread and metastasis of laryngeal cancer. Expert Tip: If you have symptoms of illness, do not delay diagnosis and go to a regular hospital for treatment in time to avoid delaying the disease and causing serious consequences.
