What are the initial symptoms of lung cancer

Symptom 1: early lung cancer clinical symptoms cough, expectoration, blood in sputum, chest tightness, suffocation, weight loss and other symptoms, X-ray, CT and MRI sputum cytology examination, serum tumor markers examination, fiberoptic bronchoscopy in the diagnosis of lung cancer have an important role.

Symptom 2: early lung cancer generally does not produce symptoms, so it is also called asymptomatic period, which can be as short as a few months and as long as a few years. It varies from person to person. At this time, patients seldom see a doctor, so it is difficult to find clinically. Some of the early symptoms of lung cancer are just general respiratory symptoms such as dry cough, chest pain, low fever and hemoptysis.

Symptom 3: the clinical manifestations of lung cancer are complex. The presence, severity and occurrence of symptoms and signs depend on the location, pathological type, metastasis and complications of the tumor, as well as the difference in response and tolerance of patients.

matters needing attention

The early symptoms of lung cancer are not obvious enough, and often can not be diagnosed when seeking medical treatment, resulting in the patient's neglect of prevention, leading to rapid deterioration of the disease. If these symptoms appear, it is better to do a detailed examination, and it is better to treat symptomatically after the condition is clear, so as not to delay the disease.
