Can lung cancer be detected early?

1. Lung cancer can usually be detected in its early stages.

2. Patients with early lung cancer can usually be examined. Many patients have no symptoms, but during health checks, lesions in the lungs are found and eventually diagnosed with lung cancer. Patients usually cannot identify tiny lesions with ordinary chest X-rays, and lung cancer can generally be checked with chest CT. CT is a tomography scan that performs a comprehensive examination of the patient's lungs. Under normal circumstances, lesions of more than 5mm can be detected in the early stages of lung cancer. Many patients have no symptoms in the early stages, some patients will experience chest discomfort such as chest tightness, cough, and blood in sputum, and some patients will experience symptoms such as fatigue and low fever. If the patient has the above symptoms, he can go to the hospital for further examination to avoid delaying the disease. If a lung cancer patient is diagnosed in the early stages, surgical treatment can be considered. The 5-year survival rate after surgery is usually more than 70%, and some patients can be cured.

3. It is generally recommended that middle-aged patients over 50 years old undergo regular physical examinations to ensure early diagnosis and early treatment.
