Some common symptoms of laryngeal cancer

Laryngeal cancer is a malignant tumor of the laryngeal mucosal epithelial tissue and is also a very common disease. It is related to factors such as long-term smoking, drinking and inhalation of harmful substances. So what are the common symptoms of laryngeal cancer ? The following is a detailed answer from relevant experts.

Supraglottic

This includes cancers that originate above the vocal cords, such as the epiglottis, aryepiglottic folds, ventricular zone and laryngeal ventricle. This type of cancer is poorly differentiated and develops quickly. Because this area is rich in lymphatic vessels, it is easy to metastasize to the lymph nodes in the deep upper neck located at the bifurcation of the common carotid artery. 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 swelling in the throat, which can be reflected to the ears and even affect swallowing. In the late stage, when the cancer erodes the blood vessels, there will be blood in the sputum, and there will often be smelly sputum. When it invades the vocal cords, there will be hoarseness and difficulty breathing. This is one of the common symptoms of laryngeal cancer.

Glottal type

Tumors confined to the vocal cords are more common in the anterior and middle thirds, are well differentiated, and are classified as grades I and II. They develop slowly, and are not easy to metastasize to the cervical lymph nodes because the vocal cords have fewer lymphatic vessels. The main symptom is hoarseness, which gradually worsens. When the tumor grows larger, it blocks the glottis, causing laryngeal wheezing and dyspnea. In the late stage, there are bloody sputum and laryngeal obstruction.

Subglottic

This refers to the cancer 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 find during 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 cancer, breathing difficulties are common. The cancer 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.

Paraglottal

: 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, and no larynx 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 an introduction to the common symptoms of laryngeal cancer. I believe everyone should have a certain understanding of laryngeal cancer. If you want to know more about laryngeal cancer, please consult online experts.
