Asymptomatic lung cancer usually belongs to the early stage, but there are often non-specific symptoms such as cough, which should be alerted.
Lung cancer is a common malignant tumor of the respiratory system, which can be caused by many factors, such as smoking, environment and heredity. In the early stage of the disease, there are often no clinical symptoms due to limited lesions, and even if there are, they may only be non-specific clinical symptoms such as cough and sputum, as well as systemic manifestations such as fatigue, fever and unexplained emaciation.
Although the specificity of early symptoms is poor, but after the discomfort should go to the hospital in a timely manner for standardized diagnosis, treatment, in order to have the opportunity of radical surgical resection, can obtain a better prognosis, a higher five-year survival rate and a longer survival time.
