What are the symptoms of lung cancer? 4 common symptoms of lung cancer

Many middle-aged and elderly people may suffer from lung cancer. Lung cancer has now become a malignant tumor with a high incidence and mortality rate. Many times it is caused by people's frequent smoking. Generally speaking, patients who have smoked for more than 20 years have a very high chance of suffering from lung cancer. Many male friends like to smoke very much, and some teenagers now think that smoking is a very cool thing, so they also start to smoke secretly. In fact, this is a very bad habit, because patients who smoke for a long time are likely to develop lung cancer. Many people suffer from lung cancer but don't know it. So, what are the symptoms of lung cancer? First, if people who smoke frequently do not have pharyngitis, bronchitis, or hoarseness when they have a cold, then they should pay attention. Because hoarseness is one of the most important early features of lung cancer. The hoarseness of people's voice caused by lung cancer is because the patient's lung cancer tissue has compressed the nerves in the patient's vocal cords, and sometimes this hoarseness occurs suddenly. Second, another obvious symptom of lung cancer patients is that the patient's body temperature will rise. In addition, many lung cancer patients will have the problem of coughing up blood. The amount of blood coughed up is not much, and it looks very bright red. This is because the surface of lung cancer tissue is very rich, so coughing up blood will occur. Third, according to scientific research, basically 30% of lung cancer patients will not show any symptoms, so these types of lung cancer patients can only be detected during physical examinations. Fourth, lung cancer patients will also have coughs, and when they cough, it is mainly an irritating choking cough, and there will be no sputum when they cough. The main symptoms of lung cancer patients are the above ones. The main cause of lung cancer is smoking, so here we strongly recommend that everyone quit smoking and drinking for the sake of their own health. If people’s city often has smog, it is recommended that people wear a mask when going out to prevent it.
