Know the early warning of lung cancer

Lung cancer is one of the most common malignant tumors, with an increasing incidence rate, ranking first among all malignant tumors. The early symptoms of lung cancer are relatively hidden, but there are still clues to be found. Patients with the following 7 symptoms should be alert to whether they have early lung cancer.

1. Cough

Symptoms of early lung cancer are often dry cough with little or no sputum, which may become persistent when symptoms worsen.

2. Bloody sputum, hemoptysis

Most of the cases are bloody or intermittent bloody sputum, usually without fever, which often does not attract the attention of patients and delays diagnosis.

3. Shortness of breath or wheezing

A small number of patients experience symptoms of chest tightness, shortness of breath, and wheezing, which cannot be ignored.

4. Weight loss

Weight loss is one of the common symptoms of malignant tumors. Unexplained weight loss must be taken seriously.

5. Hoarseness

Some patients experience hoarseness, especially male smokers, who should consider the possibility of lung cancer.

6. Chest pain

Nearly half of the patients have chest pain of varying degrees, which may include irregular dull pain and hidden pain. Especially when there is tenderness in the ribs, shoulder blades, and spine, one should be more vigilant.
