What are the early symptoms of small cell lung cancer

What are the early symptoms of small cell lung cancer? Because the incidence of this disease is constantly increasing, many people want to know what the symptoms of this disease are, because the earlier the examination, the more helpful it is for treatment. Let's learn about the early symptoms of small cell lung cancer together!

Cough is the most common symptom. Cough caused by small cell lung cancer may be related to changes in bronchial mucus secretion, obstructive pneumonia, pleural invasion, atelectasis and other intrathoracic complications. When the tumor grows in the bronchial mucosa above the segment with a larger diameter and sensitive to external stimuli, it can cause a cough similar to that caused by foreign body stimulation. The typical manifestation is paroxysmal irritating dry cough, which is often difficult to control with general cough suppressants. When the tumor grows in the smaller bronchial mucosa below the segment, the cough is often not obvious or even absent. For patients who smoke or suffer from chronic bronchitis, if the cough becomes more severe, the frequency changes, and the nature of the cough changes, such as a high-pitched metallic sound, especially in the elderly, you should be highly alert to the possibility of small cell lung cancer.

Blood in sputum or hemoptysis is also a common symptom of small cell lung cancer. Because the tumor tissue is rich in blood supply and brittle in texture, blood vessels rupture during severe coughing, causing bleeding. Hemoptysis may also be caused by local tumor necrosis or vasculitis. The characteristics of hemoptysis in small cell lung cancer are intermittent or persistent, repeated small amounts of blood in sputum, or small amounts of hemoptysis. Occasionally, large blood vessels rupture, large cavities form, or tumors rupture into the bronchial and pulmonary vessels, leading to uncontrollable hemoptysis.

Healthy people, do not smoke, stay away from secondhand smoke pollution. Try to avoid outdoor air pollution and kitchen fumes. Choose environmentally friendly decoration materials. Eat a balanced diet, eat more grains, vegetables, and fruits. Maintain an optimistic and positive attitude towards life and improve psychological adaptability. Patients should eat a light diet during chemotherapy, avoid greasy, indigestible foods and fried foods. Eat more fresh vegetables and fruits, eat small meals frequently, match food reasonably, diversify the recipes, and eat a balanced diet. During the chemotherapy interval, pay attention to avoid fatigue, rest, and regular work and rest to avoid infection.
