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

The early symptoms of lung cancer are generally not specific, and are mainly symptoms of common respiratory diseases, most commonly coughing and expectoration. As the disease progresses, the patient's sputum will contain blood. Middle-aged and elderly people should be highly alert to the possibility of lung cancer when blood appears in their sputum. The following is an introduction to the symptoms of lung cancer:

1. Clubbing is also called drumstick finger. The early symptoms of this type of lung cancer are hypertrophy of the first joints of the fingers and toes, protrusions and bending of the nails, and often accompanied by pain. According to foreign reports, 21% of lung cancers are accompanied by clubbing in the early stage, and most of them disappear after lung cancer surgery.

2. Hemoptysis: This early symptom of lung cancer occurs in about half of patients. If a male smoker over 40 years old has blood in his sputum, blood streaks or small blood clots, the possibility of lung cancer is quite high.

3. Polymyositis: About 85% of cases of polymyositis precede the typical symptoms of lung cancer. The early symptoms of this type of lung cancer include progressive general weakness and loss of appetite. When the symptoms worsen, the patient may have difficulty walking and getting out of bed.

4. Cough is also an early symptom of lung cancer. It can be a mild dry cough or a severe cough, with varying amounts of sputum. Patients with chronic long-term coughs should be alert to lung cancer if the nature of their cough changes, such as frequency or irritating dry coughs.

Since the early symptoms of lung cancer are not typical, they are very easy to be ignored in the early stages. Therefore, it is recommended that middle-aged and elderly people undergo regular physical examinations, especially those in the high-risk group for lung cancer. When similar symptoms occur, they need to go to a regular professional hospital for diagnosis in time so that they can receive timely treatment.
