It is very important to choose the treatment method for lung cancer according to the different diseases of lung cancer patients. It is not only related to the efficacy of the treatment, but also may affect how long the patient’s life will be prolonged. Causes of lung cancer Lung cancer has become one of the fastest growing malignant tumors in terms of morbidity and mortality, and one of the most threatening to human life. According to the statistics, the most common causes of lung cancer include the following lung cancer has become one of the malignant tumors with the fastest growing incidence and mortality rate, and one of the most threatening to human life. According to statistics, the most common causes of lung cancer include the following: smoking, occupation and environment, and atmospheric pollution. These categories are due to the inhalation of a large number of carcinogenic substances, such as benzo(a)pyrene and nitrosamines. In addition, ionizing radiation also has a great impact on the lungs. Finally, genetic factors are also a possibility to cause lung cancer. Treatment of lung cancer Lung cancer is best treated and best controlled when it is first detected. If treatment is delayed, the disease will quickly worsen and may even lead to uncontrollable and eventually fatal. These methods are generally used for lung cancer treatment in early stage. 1.Surgery: Among the early treatment options, surgery is often used as the preferred method. In case of primary early stage lung cancer, the five-year survival rate of patients can reach 80%-90% if the cancer body is removed by radical surgery. However, for small cell lung cancer with lymph node metastasis, surgical resection is not recommended because of the poorer effect. Surgery for early-stage lung cancer is often associated with different degrees of complications and is prone to recurrence after surgery. In early stage lung cancer surgery, it is usually combined with Chinese medicine treatment and biological therapy, which can enhance the immune function of patients, promote postoperative recovery and effectively prevent and slow down postoperative complications or recurrence and metastasis. 2.Chemotherapy: chemotherapy is also a common method of early treatment and is more often used as postoperative adjuvant therapy to kill residual cancer cells in the body and prevent postoperative recurrence and metastasis. Chemotherapy usually has certain toxic side effects, which will affect patients’ physical function and treatment enthusiasm, so it is usually used in conjunction with traditional Chinese medicine and biological therapy to reduce toxicity and increase effectiveness. 3.Radiotherapy: Radiotherapy is mostly used for adjuvant treatment to consolidate the efficacy and reduce the recurrence after surgery. However, the side effects of radiotherapy are great, and the treatment process must be based on the patient’s physical condition and the use of Chinese herbal medicine to regulate the root. 4.Chinese herbal medicine treatment: Chinese herbal medicine treatment has small side effects and wide indications, which can effectively make up for the shortcomings of Western medicine and effectively enhance the treatment effect. Therefore, Chinese medicine treatment usually accompanies the whole treatment stage to prevent postoperative complications and speed up postoperative recovery. 5.Biological therapy: Biological therapy mainly cultivates anti-cancer cells in vitro and then transfuses them back into the patient’s body to achieve scientific anti-cancer. It aims to mobilize the defense mechanism of patients’ body, regulate the biological response of patients, activate immune cells, kill cancer cells and realize the treatment of tumor from the root. The effect of lung cancer treatment is closely related to the time of treatment, so patients must choose the treatment method as soon as possible after diagnosis.
