As we all know, early stage of lung cancer is not easy to be detected, and once it is detected, it is often in the middle and late stage. Therefore, many patients are worried about how long they can live in the middle and late stage of lung cancer, in fact, how long they can live in the middle and late stage of lung cancer is inseparable from many factors. How long can lung cancer live in the late stage is related to patient’s condition: 1. There is superior vena cava in the right side of mediastinum, which transmits venous blood from upper limbs, head and neck back to heart. If the tumor invades the right side of mediastinum and compresses the superior vena cava, it will initially make the jugular vein angry due to poor reflux, and finally lead to facial and neck edema, which needs to be diagnosed and treated in time. 2. Invasion of the pleura can cause pleural effusion, which is often bloody. A large amount of fluid can cause shortness of breath. In addition, the cancer invades the pleura and chest wall, which can cause continuous and severe chest pain. 3.Upper lobe top lung It can invade and compress the organ tissues located in the upper thoracic opening. Such as the first rib, subclavian artery, brachial plexus nerve, cervical sympathetic nerve, etc., producing severe chest pain, upper limb venous anger, edema, arm pain and upper limb movement disorder, cervical sympathetic nerve syndrome such as ipsilateral upper eye and face drooping, pupil narrowing, eye sunken, no sweat on face. How long can lung cancer live in late stage is inseparable from treatment methods: 1. Chemotherapy How long can lung cancer live in late stage? It has an important position in lung cancer treatment. According to the current view, no matter early or late stage, no matter surgery or radiotherapy, it should be combined with chemotherapy to improve the survival rate. 2.Surgical treatment In early stage lung cancer, radical lobectomy should be performed as much as possible, and while completely removing the primary cancer foci and removing the lymph nodes in the lung gate, healthy lung tissues should be preserved as much as possible to achieve survival; in more advanced stage lung cancer patients, surgery should be performed to remove the primary cancer and remove the metastatic lymph nodes as much as possible, supplemented with radiation therapy, chemotherapy and other treatments. 3.Traditional therapy Chinese medicine treatment At present, traditional therapy Chinese medicine is not ideal for lung cancer, but it is suitable for late stage patients who cannot undergo surgery, radiotherapy and chemotherapy. It can relieve symptoms, reduce pain and improve life quality, and is more commonly used in clinical practice. 4.Interventional therapy Interventional therapy for lung cancer has a lot of advantages. In the case of middle and late stage of lung cancer, whether to choose interventional therapy depends on the condition.
