A survey found that 80% of lung cancer patients are already in the late stage when they are first diagnosed, which makes the overall results of lung cancer diagnosis and treatment still unsatisfactory. The incidence of lung cancer in the elderly is getting higher and higher, and the majority of lung cancers are squamous cell carcinomas, followed by adenocarcinomas. The general symptoms of lung cancer in the elderly mainly include:

First, the disease onset is slow and the course is long, with an average course of 5.2 months.

Second, the clinical manifestations are mostly cough, chest pain, blood in sputum or a small amount of hemoptysis;

Third, chest X-rays mainly show mass shadows, infiltrative lesions, atelectasis, and pleural effusion;

Fourth, there are many comorbidities, mainly chronic obstructive pulmonary disease and tuberculosis;

Fifth, the misdiagnosis rate is high, and it is often misdiagnosed as pneumonia, tuberculosis, and tuberculous pleurisy;
