In general, how long advanced lung cancer patients can live varies depending on the treatment effect and physical function, but as long as they choose appropriate treatment methods, they can improve their symptoms and prolong their survival. With the continuous improvement of treatment methods, new treatment methods and drugs are increasingly used in the treatment of advanced lung cancer, and the survival period of patients with advanced lung cancer is significantly higher than before. Patients should not be affected by the question of how long they can live with advanced lung cancer, nor should they believe in the advertisements that advertise how long a certain drug can make lung cancer live. The question of how long a patient can live in advanced lung cancer is not necessarily an exact answer for any patient, and it is most important to receive regular treatment as soon as possible. Whether or not the treatment method for advanced lung cancer is appropriate is the most important factor in how long one can live with advanced lung cancer. As far as the treatment methods for advanced lung cancer are concerned, the possibility of surgical resection is very low, and the main clinical treatment methods for advanced lung cancer are radiotherapy, chemotherapy and Chinese medicine. 70% of advanced lung cancer patients can have their symptoms relieved after radiotherapy, and external radiotherapy with different doses and split amounts can relieve the local symptoms of primary or metastatic foci. Radiation therapy should be used with caution for patients with advanced lung cancer who are weak. In addition, the most commonly used chemotherapy regimen for advanced lung cancer patients is platinum-based regimen. In addition, paclitaxel, norethindrone, gemcitabine and other drugs are also widely used in the treatment of advanced lung cancer. However, as the duration of chemotherapy increases, its therapeutic toxicity also gradually increases. Therefore, the selection of chemotherapy drugs and chemotherapy duration should be based on tumor remission, symptom relief and treatment-related toxicity. In view of the toxic side effects of radiotherapy on human body, Chinese medicine treatment can be combined in the treatment of advanced lung cancer to enhance the effect and reduce the toxicity. For advanced lung cancer patients with extensive metastasis and weak body function, who can hardly tolerate chemotherapy, conservative treatment with TCM can be used. Although the short-term effect is not as obvious as chemotherapy, the long-term effect is good, and it is effective in improving the quality of survival and prolonging the survival period. How long can advanced lung cancer patients live? This is a question that many patients with advanced lung cancer and their family members are concerned about. The treatment of lung cancer is a systematic process which involves many factors. In general, how long can advanced lung cancer patients live, in other words, the survival period of advanced lung cancer patients mainly depends on whether the treatment method is appropriate and the physical function of patients. In addition, patients and family members of advanced lung cancer should learn more about the treatment knowledge of advanced lung cancer and communicate more with the attending physicians, which will help to extend the survival period of advanced lung cancer. The main influencing factors of how long advanced lung cancer can live are the treatment method and patient’s physical condition. The improvement of the patient’s body function is also an important factor in determining how long a patient can live with advanced lung cancer. A good body function and strong immunity can resist the development of cancer and tolerate various drug treatments. Therefore, it is extremely important for patients with advanced lung cancer to improve their immune function and strengthen their resistance to tumors. In terms of diet, patients with advanced lung cancer should eat more foods with immune enhancing and anti-lung cancer effects, such as barley, yam, jujube, walnut, turtle, etc.; cough and phlegm should eat white fruit, radish, mustard, almond, orange peel, etc.; foods to reduce side effects of radiotherapy and chemotherapy should be eaten: goose blood, mushroom, shark, cinnamon, etc. One can also rely on taking herbal medicines that have the effect of tonifying the spleen and benefiting the kidneys, such as the Chinese Academy of Traditional Chinese Medicine’s Jianshuanyi Kidney Granules to enhance immune function. When patients undergo radiotherapy, not only are cancer cells destroyed, but also white blood cells are destroyed and immunity is weakened, resulting in 40%-50% of cancer patients dying from complications such as loss of appetite and weight loss, reducing the survival rate of patients. Ginsenoside Rh2 acts on radiotherapy patients to stabilize their white blood cells, protect them from other infections, and prolong their lives. In combination with general chemotherapy agents, it acts as a potentiator.
