The earliest signs of central lung cancer

The earliest signs of central lung cancer are:

Central lung cancer refers to large bronchial cancer that occurs above the bronchial opening of the lung, close to the hilum of the lung. Usually, the earliest signs of central lung cancer are cough, sputum, limited wheezing, etc.

1. Cough:

Central lung cancer lesions can compress surrounding tissues and affect the normal exchange of gas, which may cause coughing symptoms.

2. Coughing up phlegm:

Central lung cancer lesions can also damage lung tissue, leading to increased production of lung secretions, coughing up sputum, and sometimes blood in the sputum.

3. Localized wheezing:

Most of the wheezing is unilateral and limited, especially during the inspiration phase. It will not disappear after coughing, but it is easy to be ignored.

In addition to the above symptoms, patients with central lung cancer may also experience chest tightness, shortness of breath and other symptoms. It is necessary to see a doctor as soon as possible, identify the cause, and actively treat it to avoid delaying the condition and affecting the patient's prognosis. Patients can eat some light and easily digestible food every day, avoid spicy, cold, and greasy food, and maintain a comfortable mood, work and rest regularly, and avoid staying up late and fatigue.
