Lung cancer is easier to diagnose in the late stage than in the early stage

The symptoms of late-stage lung cancer vary depending on the patient's physical condition. Lung cancer is more serious in the late stage and requires timely symptomatic treatment. However, compared with patients with early-stage lung cancer, the various clinical symptoms of the late stage are very obvious.

1. Symptoms of locally advanced lung tumors: The chest cavity is a very complex space. Three-quarters of the lung surface is surrounded by the chest wall, which is composed of a thin layer of lining (parietal pleura), fat, muscle, ribs and skin in different proportions. Tumor invasion of any of the above parts will cause pain. Therefore, most patients with lung tumors that have spread regionally in the chest have symptoms of chest pain.

2. Lung tumor pain: Pain is a common symptom in patients with advanced lung tumors. Most patients with lung tumors that have spread regionally in the chest have chest pain.

3. Hoarseness is one of the late-stage symptoms of lung tumors: the recurrent laryngeal nerve that controls the left side of the voice function goes down from the neck to the chest, bypasses the large blood vessels of the heart and goes back up to the larynx, thus controlling the left side of the voice organ. Therefore, if the tumor invades the left side of the mediastinum and compresses the recurrent laryngeal nerve, hoarseness will occur, but there will be no sore throat or other symptoms of upper respiratory tract infection.

4. Facial and neck edema is also a common symptom in the late stage of lung tumor. If the tumor invades the right side of the mediastinum and compresses the superior vena cava, the jugular vein will initially become distended due to poor reflux, and eventually it will lead to facial and neck edema, which needs to be diagnosed and treated in time.

5. Shortness of breath and pleural effusion are also symptoms of advanced lung cancer.
