What are the symptoms of laryngeal cancer in the early stages of the disease?

What are the symptoms of laryngeal cancer? I believe that many laryngeal cancer patients do not know much about the symptoms of laryngeal cancer. Even most patients delay treatment because they do not pay attention to the symptoms of early laryngeal cancer . Understanding the symptoms of laryngeal cancer plays a key role in whether patients can receive timely treatment.

Symptoms of laryngeal cancer include:

1. Glottic type: Cancers confined to the vocal cords, with more cases in the anterior and middle 1/3, better differentiated, and classified as grades I and II. They develop slowly, and are not easy to metastasize to the cervical lymph nodes due to the small number of lymphatic vessels in the vocal cords. The main symptom is hoarseness, which gradually worsens. When the tumor grows, it blocks the glottis, causing laryngeal wheezing and dyspnea, and bloody sputum and laryngeal obstruction in the late stage.

2. Paraglottic type: refers to cancer originating from the laryngeal ventricle, 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 the tumor is not 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.

3. Supraglottic type: includes cancers originating from the parts above the vocal cords, such as the epiglottis, aryepiglottic folds, ventricular bands and laryngeal ventricles. 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 later, 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, there will be blood in the sputum, and there will often be smelly sputum. When the vocal cords are invaded, there will be hoarseness and difficulty breathing.

4. Subglottic type: 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 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 cancer, 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.

The above are the symptoms of laryngeal cancer. Through the introduction of experts, I believe you have a certain understanding of the symptoms of laryngeal cancer. If you have any questions about the symptoms of laryngeal cancer, please consult our online experts.
