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

Lung cancer is difficult to treat. The key is that many people do not know how to treat lung cancer in its early stages. As a result, the treatment effect will not be very good, and it is easy to fail to be cured, which makes it even more difficult to treat. Here are some common early symptoms of lung cancer.

(1) Cough. Most of the coughs are occasional dry coughs with little or no sputum, and may contain a small amount of white foamy sputum. They often occur after exertion. The coughing time is irregular and has nothing to do with body position.

(2) Hemoptysis or bloody sputum. It is caused by necrosis and ulceration of cancerous tissue, which leads to rupture of capillaries. The amount of hemoptysis and the duration of hemoptysis are related to the degree of vascular damage in the cancerous tissue. It is usually persistent, with blood streaks or small blood clots in the sputum. The blood is bright red or dark red and is generally difficult to control with treatment. Hemoptysis or bloody sputum usually contains less blood. In a few cases, the cancer erodes the large blood vessels, which can cause massive hemoptysis.

(3) Chest pain Chest pain usually occurs in the middle or late stages of lung cancer. However, if the tumor is located near the pleura, chest pain may occur earlier and manifest as irregular dull pain or pain. When the tumor directly invades the pleura, there may be sharp chest pain, which worsens when coughing or breathing.

(4) Fever. Lung cancer rarely causes fever in the early stages, but when cancerous tissue necroses, it can cause low or moderate fever, which is ineffective with antibiotic treatment. When central lung cancer with lesions close to the hilum of the lung grows in the bronchus and develops to the point of obstruction or semi-obstruction of the bronchial lumen, it can cause obstructive pneumonia and systemic fever. At this time, the body temperature is generally around 38'C. Antibiotic treatment can reduce the fever, but if the obstructive lesions are not removed, pneumonia can recur.

These are our common early symptoms of lung cancer. Lung cancer has many symptoms and is difficult to treat. Therefore, the earlier the treatment, the better the effect. This is a question that every lung cancer patient should understand. I hope these can help everyone cure the disease and recover soon.
