What are the symptoms of lung cancer?

Cough: this is one of the most common early symptoms of lung cancer, which is manifested as an irritating dry cough of unknown cause. Some will also have slightly white sputum. If you get up in the morning and cough, you will find small blood clots or tiny bloodshot in the sputum. When you find this situation, especially patients with a history of smoking, you must pay attention to it and go to a regular hospital for diagnosis in time. When the tumor grows, it will block the trachea, which will lead to the narrowing of the trachea. At this time, the cough will get worse, and this cough is persistent.

Hematemesis: This phenomenon is mainly due to the sufficient blood supply of tumor tissue, so lung cancer patients will have persistent or intermittent blood when coughing. Most of the sputum is bloody and bright red. When it is not serious, the area is small, and the cough is harsh and sharp. The more serious the illness, the sharper the cough, and with the development of the illness, there will be a large area of hemoptysis. At this time, it is necessary to make a diagnosis in time so as to get treatment at the first time.

Chest tightness and shortness of breath: this is because the lump blocks the trachea or hurts the pleura. Patients will feel chest tightness and shortness of breath, will be gentle when lying down and resting, and will cough when they are slightly active. Chest tightness is not obvious in the early stage of cancer, but they feel chest tightness. If they have bronchitis or emphysema, this feeling of chest tightness and shortness of breath is more obvious. Therefore, if they suffer from emphysema or bronchitis, they will feel chest tightness and shortness of breath.

Weight loss: The weight loss of lung cancer is not obvious in the early stage, but obvious in the middle and late stage, and the weight loss is rapid. In other words, the diet drops, and physically, I always feel tired and weak. Because of lack of physical strength, he is said to be taciturn. This is because the rapid growth of tumor will consume a lot of nutrients, and the patient's lack of food and sleep will weaken his physical strength, and his resistance will decline at this time.

Chest pain: the pain of lung cancer is manifested as unfixed, diffuse chest pain, back pain, chest pain and so on. This is caused by lung tumor invading pleura, ribs or chest wall. This kind of pain can be manifested as severe chest pain or dull pain, sometimes dull pain, but it will get worse when coughing, and this kind of cough is not affected by climate, which is different from bronchitis. If you have this kind of chest pain, you should go to a regular hospital in time to diagnose the condition.
