Lung cancer is the cancer with the highest mortality rate, and even in the United States, a country with very advanced medical care, millions of people die of lung cancer each year. In recent years, lung cancer has become the number one killer threatening women’s health! There are many causes of lung cancer, such as smoking, occupational factors, atmospheric pollution, genetics, drugs, psychosomatic, and chronic diseases of the lungs. However, smoking is recognized as the main culprit of lung cancer. Some data prove that 85% of lung cancer is related to smoking, and the incidence of lung cancer in long-term smokers is 10 times higher than that of non-smokers. The treatment methods for lung cancer mainly include surgery, radiotherapy, chemotherapy and “non-toxic anti-cancer green therapy”. For early stage lung cancer patients with small lesions, no distant metastasis and good general condition, surgery should be used. (I) Surgery: The purpose of surgery is to completely remove the primary lung tumor and local metastatic lymph nodes, and to preserve healthy lung tissues as much as possible. However, surgical treatment is contraindicated in the following cases: (i) supraclavicular and axillary lymph node metastasis. ②Distant metastasis, such as brain, bone, liver and other organs metastasis. (iii) Extensive hilar and mediastinal lymph node metastasis. ④Pleural metastasis, cancer invading the chest wall and ribs, although it can be removed together with the diseased lung, but the efficacy is not good, and pneumonectomy should be considered carefully. ⑤ Patients with cardiac, pulmonary, hepatic and renal insufficiency and poor general condition. The cure rate (5-year survival rate) is about 25% with surgery as the main treatment, along with preoperative or postoperative radiotherapy and chemotherapy. (b) Radiotherapy: Radiotherapy is a means of local elimination of lung cancer lesions. Among all types of lung cancer, small cell lung cancer is more sensitive to radiotherapy, followed by squamous carcinoma, and adenocarcinoma and fine bronchial lung cancer are the lowest. The 3-year survival rate is about 10% when radiotherapy is applied alone. Radiotherapy may cause fatigue, loss of appetite, hypothermia, suppression of bone marrow hematopoiesis, radiation pneumonia and other reactions and complications, so special care should be taken in treatment. (3) Chemotherapy: The efficacy of chemotherapy is better for low differentiated lung cancer, especially small cell lung cancer. However, the average cure rate of chemotherapy for lung cancer is very low, below 5%. While chemotherapy kills tumor cells, it also kills cells of normal tissues, which are important immune defense system of human body. If the immune system of human body is destroyed, the cancer may develop rapidly and cause serious consequences. (D) Chinese medicine treatment: It is adapted to all stages and types of lung cancer. It can effectively improve patients’ painful symptoms (coughing, coughing up blood, chest pain, wheezing, etc.) and control and eliminate pleural effusion. The “non-toxic anti-cancer green therapy” can be treated alone or in combination with surgery, radiotherapy and chemotherapy. After surgery, the treatment can eliminate the remaining cancer cells in human body and prevent recurrence; radiotherapy and chemotherapy with the treatment can minimize the toxicity of radiotherapy and increase its sensitivity, and the total clinical stability rate is over 83%, which greatly improves the five-year cure rate of lung cancer.
