Early symptoms of lung disease?

Cough is the most common symptom. If cough occurs frequently and lasts for a long time, especially when the sputum is bloody, attention must be paid to it. More than half of lung cancer patients have continuous cough in the early stage, and it is very frequent.

Hoarseness is mainly caused by tumor compression of recurrent laryngeal nerve. The recurrent laryngeal nerve (RLN), which controls the left vocal function, descends from the neck to the chest, bypasses the great blood vessels of the heart and goes up to the larynx, thus dominating the left side of the vocal organ. Therefore, if the tumor invades the left side of the mediastinum and compresses the recurrent laryngeal nerve, hoarseness will occur, but there are no other symptoms of sore throat and upper respiratory tract infection.

Chest tightness and dyspnea are common symptoms in various types of lung cancer. Tumor causes obstruction of large airway ventilation, lack of ventilation in lung lobes, and lack of oxygen in blood, which will cause chest tightness and dyspnea. Early lung cancer chest pain is mild, mainly for dull pain, dull pain, location is not necessarily. If the pain continues to occur, then the cancer may involve the pleura.

matters needing attention

Modern people pursue the delicacy of food, and often forget the health of grains. For patients with lung cancer, eating more cereals is good for the body and digestion. Cancer cells will affect the operation of major organs. Coarse grains are rich in dietary fiber, which can help the digestion of intestinal tract and prevent constipation.
