How to prevent laryngeal cancer How to prevent laryngeal cancer

With the increasing number of people suffering from laryngeal cancer, laryngeal cancer has been taken seriously by many people. How do we prevent laryngeal cancer in our daily life? The following editor will introduce you to the methods of preventing laryngeal cancer, welcome to read.

Specific preventive measures for laryngeal cancer

1. No smoking

Smoking can directly damage the organ and cause laryngeal cancer. The longer you smoke, the higher the incidence of laryngeal cancer. Nicotine, coal tar and benzopyrene produced by cigarettes are all carcinogens.

2. Don’t drink too much

Long-term heavy drinking causes congestion and edema in the throat, and leads to malnutrition and low immune function, laying the foundation for the formation of cancer.

3. Prevent the harm of bad eating habits

Some people often eat hotpot, malatang and other stimulating foods with friends regardless of winter or summer. Such long-term eating habits are harmful not only to the throat, but also to the eyes, trachea, lungs, esophagus, stomach, etc., which can not only cause diseases, but also worsen and form cancer.

4. Stay away from chemical carcinogens

Chemical carcinogens related to laryngeal cancer include sulfur dioxide, chromium, arsenic, etc. The living and production environment is polluted by air. Inhaling the above harmful gases and dust will damage the throat, so protection must be done.

5. Pay attention to precancerous lesions

Laryngeal leukoplakia is a precancerous lesion of laryngeal cancer. It is a white patch on the mucosa of the vocal cords due to poor keratinization. It is a pathological change caused by upper respiratory tract infection, smoking, harmful gas stimulation, excessive voice use, etc. It is closely related to the formation of laryngeal cancer and must be actively prevented and treated. There are also laryngeal keratosis, chronic hypertrophic laryngitis, papilloma, etc., which need to be closely observed and actively prevented and treated.

6. Good sanitary environment to prevent virus infection

Develop a good hygiene environment and prevent viral infection, because viral infection is closely related to the occurrence of laryngeal cancer. It is generally believed that viruses can change the nature of cells and cause abnormal division. Viruses can attach to genes and be passed on to the next generation of cells, causing cancer.

7. Try to avoid air pollution

Long-term inhalation of harmful gases in severely polluted air, such as sulfur dioxide, and industrial dust, such as chromium and arsenic, can easily lead to laryngeal cancer.

8. Continuously improve the body's immune function

Pay attention to oral hygiene and prevent and treat respiratory diseases, avoid viral and bacterial infections; eat more fresh vegetables and fruits. Some studies have confirmed that the vitamin C and carotene contained in them can reduce the incidence of laryngeal cancer.

Early detection of tumors is most important

Hoarseness: This is the first symptom of laryngeal tumors. At first, it feels difficult to speak, followed by persistent hoarseness, which gradually worsens. The degree of hoarseness is more serious than chronic laryngitis.

Abnormal sensation in the throat: foreign body sensation, urgency or discomfort in swallowing in the throat are typical symptoms of supraglottic laryngeal cancer. Unfortunately, the early symptoms of this type of disease are not obvious and are not easy to detect with laryngoscopy until they develop into the second or third stage. If there is discomfort in the throat, a comprehensive and detailed examination should be done. Do not treat it only as abnormal sensation in the throat or chronic pharyngitis, so as not to delay the disease.

Cough and hemoptysis: Coughs are mostly irritating and dry, with blood in the sputum. When the tumor grows, it will make it difficult for secretions in the trachea to be discharged, which can easily cause respiratory infections.

Reflex pain: If a laryngeal tumor ruptures, is inflamed, or develops laryngeal cartilage periostitis, it can cause nerve reflex pain, manifested as headache or ear pain on the same side. This symptom is more common in patients with supraglottic tumors.

Neck lumps: Supraglottic laryngeal cancer often causes lumps to appear in the upper neck and behind the mandibular angle. Patients often do not have any obvious symptoms, but metastasis occurs early.
