What are the symptoms of early and late stage lung cancer?

Lung cancer can generally be preliminarily diagnosed through symptoms, signs, and imaging examinations. If you want to clarify the stage, you need to perform a pathological tissue biopsy for further confirmation.

1. Preliminary diagnosis

1. Symptoms: Patients with early-stage lung cancer usually have no obvious discomfort, but as the disease progresses, they may develop symptoms such as coughing, sputum, and hemoptysis;

2. Physical signs: When the tumor invades the pleura, chest pain will occur. When the tumor compresses the recurrent laryngeal nerve, it will also cause hoarseness. In addition, if the tumor is large, it may also cause the trachea to be squeezed, causing difficulty breathing;

3. Imaging examinations: such as chest X-rays or CT scans, can help detect lung lesions and observe whether there is lymph node metastasis.

2. Clarify the staging

For people who are suspected of having lung cancer, it is also necessary to combine the puncture biopsy method for testing, which can directly remove a small amount of cancer cells for testing and quickly determine whether cancer lesions have appeared. At the same time, it can also be combined with pathological examination to accurately determine the severity of the disease and formulate appropriate treatment plans based on the examination results.

It is recommended that people with suspected lung cancer seek medical treatment in a timely manner, complete relevant examinations under the guidance of a doctor and receive standardized treatment. They should pay attention to quitting smoking and drinking, and avoid being in a secondhand smoke environment for a long time to avoid aggravating the damage to the respiratory mucosa.
