What are the early symptoms of lung cancer

Symptom 1: cough is the earliest and most common symptom of lung cancer patients. As the onset is often similar to a cold or bronchitis, it is easy to be ignored. Therefore, those who have no chronic respiratory diseases in the past, especially those over 40 years old, should go to the hospital for examination after active treatment if their cough lasts for three weeks and can not be stopped. Be careful of lung cancer.

Symptom 2: hemoptysis is the second common symptom of lung cancer. It is often caused by the invasion of bronchial mucosa by cancer tissue. The amount of hemoptysis is generally small, often bloody sputum, lasting for weeks, months or intermittent attack. Because the amount of hemoptysis is small or appears intermittently, it is easy to be neglected. In fact, more than middle-aged blood sputum, about 1 / 4 caused by lung cancer. Therefore, when there is unknown cause of phlegm and blood, do not be careless.

Symptom 3: chest pain accounts for more than half of lung cancer patients, especially peripheral lung cancer, chest pain can be the first symptom. That's because the cancer infiltrates the pleura. Chest pain is often fixed in the lesion site, and in the early stage, it is often intermittent dull pain and discomfort. It can be aggravated by postural changes, deep breathing and coughing. Therefore, if there is chest pain in the fixed position due to unknown reasons, the corresponding examination should be carried out as soon as possible.
