What are the characteristics of laryngeal cancer?

In recent years, laryngeal cancer has become a major disease that endangers human life. It has brought great pain and distress to mankind. Do you know the characteristics of laryngeal cancer? The following experts will introduce us to the characteristics of laryngeal cancer.

Characteristics of laryngeal cancer 1. Supraglottic type includes cancers originating from the parts above the vocal cords, such as the epiglottis, aryepiglottic folds, ventricular zone and laryngeal ventricle. This type of cancer is poorly differentiated and develops rapidly. Because the lymphatic vessels in this area are abundant, it is easy to metastasize to the lymph nodes of the deep upper neck group located at the bifurcation of the common carotid artery. The early symptoms include a foreign body sensation in the throat and discomfort in the throat. When the surface of the cancer ulcerates, there will be throat swelling, which can be reflected to the ears and even affect swallowing. In the late stage, after the cancer erodes the blood vessels, blood is present in the sputum, and there is often smelly sputum. When the vocal cords are invaded, there will be hoarseness and difficulty breathing.

Characteristics of laryngeal cancer 2. Glottic type: Cancer limited to the vocal cords. Previously, there were more tumors in the middle 1/3, which were well differentiated and belonged to grades I and II. They developed slowly. Since there were fewer lymphatic vessels in the vocal cords, they were not easy to metastasize to the cervical lymph nodes. The main symptom was hoarseness, which gradually worsened. When the tumor grew larger, it blocked the glottis, which could cause laryngeal wheezing and dyspnea. In the late stage, there were bloody sputum and laryngeal obstruction.

The 3rd characteristic of laryngeal cancer is the subglottic type, which is a tumor located below the vocal cords and above the lower edge of the cricoid cartilage. Because this area is relatively hidden, it is not easy to be found in routine laryngoscopy. There may be no symptoms in the early stage, but cough and bloody sputum may occur later. In the late stage, due to the blockage of the subglottic area by the tumor, breathing difficulties are common. It may also penetrate the cricothyroid membrane, invade the thyroid gland and the anterior soft tissue, and may also infiltrate along the anterior wall of the esophagus.

Characteristics of laryngeal cancer 4. Paraglottic type: refers to cancer originating from the laryngeal cavity, also known as transglottic cancer. This area is very hidden. There may be no symptoms in the early stage, and it is very easy to spread to the lateral paraglottic space. Its clinical characteristics are: hoarseness is the first symptom, and the vocal cords are often fixed first, but no tumor is seen. Later, as the cancer spreads to the paraglottic space, infiltrates and destroys the laryngeal cartilage, there may be sore throat. If it invades the thyroid cartilage wing plate and cricothyroid membrane on one side, the laryngeal cartilage support can be felt on that side, and there is an irritating dry cough. Generally, it is not confirmed until it develops to two areas.

The above is what experts have introduced to us about the characteristics of laryngeal cancer.
