Tumor is a new organism formed by abnormal differentiation and excessive proliferation of local tissue cells in the organism caused by the long-term effect of various tumor-causing factors and changes in genetic material. Benign tumors have less impact on the organism, while malignant tumors not only proliferate rapidly locally, but also destroy adjacent tissues and metastasize to other parts to continue to grow, causing serious harm to the organism. The survival period of cancer is hard to predict, and any answer to predict how long cancer will live will not be accurate, and the same is true for lung cancer. Once a patient is diagnosed with early-stage lung cancer and must receive regular and systematic treatment, there are many factors affecting the survival time of patients, which varies greatly from one individual to another. Some early-stage lung cancer patients live for decades, while others only live for a few months. Besides radiotherapy and chemotherapy, biological treatment is also a good choice for lung cancer. Chinese medicine is also effective in treating lung cancer and has no side effects.
