What should I check for throat square dance

Which three symptoms of the throat recur, so we should be vigilant and screen lung cancer in time? The question is, what symptoms of the throat may be related to lung lesions? 1, feeling a foreign body irritation in the throat, dry cough: According to the materials mastered in clinical medicine at this stage, cough is a typical and very common first symptom of lung cancer. This kind of cough is different from common respiratory diseases, which is caused by the stimulation of cancer and the metabolic changes of bronchial mucosa. Therefore, patients often have dry or choking cough due to similar dirty things, and the drugs for relieving cough and resolving phlegm are not easy to operate. The cough degree of patients will gradually deepen, the frequency will become more and more frequent, and the cough characteristics will also change;

2, expectoration: The early stage of lung cancer is mainly characterized by a good dry cough, but with the continuous increase of bronchial mucosal metabolism, it will gradually develop from dry cough to expectoration. At the same time, because the tumor tissue is rich in blood supply, but the capillaries are relatively sensitive, it is easy to cause blood vessel rupture and bleeding in the case of coughing. While coughing and expectoration, patients may have symptoms such as intermittent or continuous sputum with blood and a little hemoptysis, and even massive hemoptysis that is difficult to control due to blood vessel rupture;

3, hoarseness: Compared with the above two symptoms, hoarseness caused by lung cancer is actually less specific, which is very easy to cause patients' caution. According to the materials available in clinical medicine at this stage, nearly 5~ 18% of lung cancer patients have hoarseness in the early stage, usually accompanied by cough.

Different from the hoarseness caused by tonsillitis, this kind of hoarseness progresses very fast, drugs can not be effectively controlled, and patients may even lose their voice completely. This is often the case because lung cancer has grown to a certain extent, squeezing the recurrent laryngeal nerve in the same direction, resulting in paralysis of the left vocal cord and hoarseness. In more serious cases, it may even develop into upper respiratory tract obstruction.
