In recent years, the incidence of laryngeal cancer is getting higher and higher, which seriously endangers people's healthy life. Laryngeal cancer is easy to be found in the early stage, so it can be treated in time to reduce the harm to patients. Understanding the symptoms of laryngeal cancer is very helpful for treatment. So it is very important to understand the early performance. Let's look at the early symptoms of laryngeal cancer.
First, hoarseness: it is the most common symptom of laryngeal cancer. Laryngeal cancer is a tumor that grows on vocal cords. Even if it is very small, it will affect the voice and cause hoarseness. Therefore, if you have hoarseness for unknown reasons and it lasts for more than two weeks, you should do a careful throat examination and don't take it lightly.
Second, abnormal laryngeal sensation: foreign body sensation or swallowing discomfort, which is a symptom of supraglottic laryngeal cancer. But this type of cancer, at the beginning, the symptoms are often not obvious, and it is not discovered until later. Tracing his medical history may last for several months.
Third, bloody cough in sputum: Because tumor stimulation can produce irritating dry cough, patients often have a sticky feeling of mucus, so they always like it? Clear your throat? It is also a common symptom of laryngeal cancer. When you take a deep breath and clear your throat, you will find blood in your phlegm. Generally, cough will continue in the middle stage, and symptoms such as blood in sputum will appear in the later stage.
Therefore, in the process of physical examination, patients in the following situations should focus on the examination and investigation of laryngeal cancer.
Any unexplained hoarseness or foreign body sensation in the throat will not be relieved after symptomatic treatment, especially for patients over 46 years old, accompanied by irritating dry cough, blood in sputum, sore throat, headache and earache, and dyspnea, so we should be highly vigilant; Cervical mass, excluding thyroid cartilage contour, thyrohyoid periosteum, upper corner of thyroid cartilage, cricothyroid membrane, thyroid gland and other variations should also be examined; The lymph nodes were swollen downward from the mandibular angle along the anterior edge of sternocleidomastoid muscle, which were hard without tenderness and decreased in activity. For long-term smoking, family history of cancer, some occupations, exposure to radioactive substances and asbestos dust, dichromate, etc. Attention should be paid to general survey and diagnosis.
? So, what are the causes of laryngeal cancer?
(1) Smoking: Tobacco burning can produce tobacco tar, among which benzopyrene can cause cancer; Tobacco smoke can stop or slow down cilia movement, make mucous membrane hyperemia and edema, make epithelial hyperplasia thicker and squamous metaplasia, and become the basis of cancer.
(2) Excessive drinking: Long-term stimulation of mucosa can denature it and cause cancer. When smoking and drinking coexist, additive and overlapping carcinogenic effects may occur.
(3) chronic inflammatory stimuli, such as chronic laryngitis or respiratory inflammation.
(4) Air pollution: Long-term inhalation of harmful gases such as sulfur dioxide and productive industrial dust such as chromium and arsenic can easily cause laryngeal cancer.
(5) Virus infection: It is closely related to the occurrence of cancer. It is generally believed that viruses can change the nature of cells and cause abnormal division; Viruses can attach to genes and pass them on to the next generation of cells to become cancerous. Human papillomavirus-16 and 18 have always been considered to be related to the occurrence and development of laryngeal cancer.
(6) Precancerous lesions: laryngeal keratosis and laryngeal benign tumors, such as laryngeal papilloma, can become cancerous after repeated attacks.
(7) Radiation: Radiation can cause cancer when treating cervical tumors.
(8) Sex hormones: Related experiments showed that the percentage of estrogen receptor positive cells in patients with laryngeal cancer increased significantly.
Therefore, we should have regular physical examinations to ensure our health. After all, health is the most important thing.
