Is laryngeal cancer contagious?

Laryngeal cancer is just a type of squamous cell carcinoma, not an infectious disease. It is not contagious. It can be said that all cancers are not contagious, because cancer is not an infectious disease, nor does it belong to the category of infectious diseases. The cause of laryngeal cancer is still unclear. However, the incidence of laryngeal cancer is closely related to certain bad living habits.

Laryngeal cancer is a very serious malignant tumor disease. We cannot delay the treatment of laryngeal cancer. We should start treatment as soon as possible to seize the best treatment opportunity to recover earlier. To avoid such a disease from causing too much harm, in order to help patients, let's talk about whether laryngeal cancer is contagious.

Is the sputum of laryngeal cancer patients contagious?

Laryngeal cancer is a malignant tumor that occurs in the throat. It is a squamous cell carcinoma and is not an infectious disease. Laryngeal cancer is divided into three categories based on the location of the tumor: supraglottic cancer, glottic cancer, and subglottic cancer. The most common type is glottic cancer, which originates from the vocal cords.

Most laryngeal cancers can metastasize to the cervical lymph nodes and distant metastases. Some patients present with cervical lymph node metastasis and distant metastasis as the first symptom, which increases the difficulty of diagnosis and is easily misdiagnosed as vocal cord polyps, vocal cord paralysis, pharyngitis, etc. The duration can be as short as 2 weeks or as long as 2 years. Patients with laryngeal cancer often have symptoms such as hoarseness, cough, hemoptysis, abnormal throat pain, difficulty breathing, and lumps in the neck.

The cause of laryngeal cancer is still unclear. However, the incidence of laryngeal cancer is closely related to certain bad lifestyle habits. Surveys have found that people who smoke and drink a lot are more likely to develop laryngeal cancer. Excessive use of the vocal cords (mostly due to occupational reasons) and long-term consumption of betel nuts can increase the chance of developing laryngeal cancer. Laryngeal cancer patients are mainly middle-aged and elderly people, and men are more likely to develop laryngeal cancer than women.

The sensation of a foreign body in the throat or pain when swallowing are early symptoms of supraglottic laryngeal cancer, but once a tumor originating from the vocal cord develops to the middle or late stages, it will also cause a foreign body sensation in the throat or pain when swallowing. If you find hoarseness or foreign body sensation, go to a large regular hospital for a laryngoscopy to confirm the condition.

We can understand that laryngeal cancer is not contagious. We hope that in the future we can look at laryngeal cancer correctly. In addition to paying attention to the prevention of laryngeal cancer, we must also actively take treatment measures for the disease and not miss the best time for treatment.
