What are the common clinical symptoms of laryngeal cancer ? The following is an introduction to the clinical symptoms of various types of laryngeal cancer.

1. Paraglottic type: Clinical symptoms of laryngeal cancer refer to cancer originating from the laryngeal cavity, also known as transglottic cancer. There may be no clinical symptoms of laryngeal cancer in the early stage, and it is easy to spread to the lateral paraglottic space. The clinical symptoms of laryngeal cancer are characterized by: hoarseness is the first symptom of laryngeal cancer, and the vocal cords are often fixed first, but no tumor is found. Later, as the cancer spreads to the paraglottic space, infiltrates and destroys the laryngeal cartilage, there may be sore throat.

2. Glottic type: Clinical symptoms of laryngeal cancer are limited to the tumor of the vocal cords, which are more common in the anterior and middle 1/3. The clinical symptoms of laryngeal cancer develop slowly. Since the vocal cords have fewer lymphatic vessels, it is not easy to metastasize to the cervical lymph nodes. The main clinical symptoms of laryngeal cancer are hoarseness, which gradually worsens.

3. Supraglottic type: This includes the clinical symptoms of laryngeal cancer that originates above the vocal cords. Because this area is rich in lymphatic vessels, it is easy to metastasize to the deep upper neck lymph nodes located at the bifurcation of the common carotid artery. The clinical symptoms of early laryngeal cancer include a foreign body sensation in the throat and discomfort in the pharynx.

4. Subglottic type: Clinical symptoms of laryngeal cancer are cancer below the vocal cords and above the lower edge of the cricoid cartilage. There may be no clinical symptoms in the early stage of laryngeal cancer, but later symptoms of laryngeal cancer include coughing and bloody sputum. In the late stage, due to the blockage of the subglottic area by the cancer, there are often clinical symptoms of laryngeal cancer such as difficulty breathing.
