In the early stage of laryngeal cancer, the general symptoms are atypical. Many people may regard it as a cold or pharyngitis, and may show symptoms of acute pharyngitis, such as foreign body sensation, sore throat and hoarseness. Some people may have nasal congestion, severe tinnitus, nosebleeds and unexplained headaches, but once these symptoms appear, they may mainly be foreign body sensation, voice change, severe cough and dyspnea. You can show symptoms.

1. Foreign body sensation in pharynx. In the early stage, there may be aversion to the throat in the morning, and there may also be phlegm cough without sore throat. In severe cases, nausea and vomiting may occur, and gastric acid secretion is excessive.

2. Refractory cough, manifested as irritating dry cough, and sometimes hemoptysis after frequent coughing will also be manifested as dyspnea, which is mostly related to tracheal obstruction after coughing and expectoration.

3. Acute dyspnea is generally related to tumor enlargement, airway compression and airway obstruction in the later stage. In severe cases, there will be difficulty breathing.

The 5-year survival rate of early laryngeal cancer can reach 85%, but the early symptoms of laryngeal cancer are not typical. I hope everyone will pay attention to the timely diagnosis and treatment of hoarseness. If you are over 40 years old and the symptoms of hoarseness last for more than one month, you should pay attention to it and go to the hospital as soon as possible to check the throat cancer. In addition, patients with sore throat, foreign body sensation in throat and blood in sputum should also go to regular hospitals in time. Because the incidence of laryngeal cancer has gradually increased in recent years, we only need to know the symptoms to help patients find and treat the disease early.

Hoarseness, foreign body sensation in the throat, dysphagia, sore throat, bloodshot sputum and dyspnea may all indicate the occurrence of laryngeal cancer, but they may be confused with "excessive internal heat" and "pharyngitis" in everyone's impression, thus missing the best treatment opportunity. Therefore, people with family history, long-term smoking and drinking history, and over 40 years old, especially men, once have hoarseness and sore throat. It often happens, and it is best to do electronic laryngoscopy after routine treatment in order to find traces of laryngeal cancer as soon as possible.
