Can lung cancer be cured by taking medicine? Nowadays, the environment we live in is severely polluted, and many people have bad lifestyle habits, which increases the chance of lung cancer. Now it can be said that lung cancer has become one of the most common cancers. , And there are many treatments for lung cancer, can lung cancer be cured by taking medicine?

　　Lung cancer has become the first cause of death from malignant tumors in China. It is expected that by 2025, China’s lung cancer patients will reach 1 million, becoming the world’s largest lung cancer country. In recent years, targeted drugs have been in the limelight in the treatment of lung cancer. Some patients even think that as long as they take targeted drugs, they do not need surgery and radiotherapy and chemotherapy. Experts pointed out that surgery is still the only way to cure patients with early lung cancer. Targeted drugs are only suitable for patients with advanced lung cancer, and at present, the problem of drug resistance cannot be solved, and patients should not blindly believe in targeted drugs. Therefore, lung cancer patients can not be completely cured by taking targeted drugs.

　　Lung cancer is one of the top ten malignant tumors with the highest incidence, and it is the "number one killer" of cancer patients. One of the reasons is that most lung cancer patients are already found in the middle and late stages. Suitable for surgery. Before the development of targeted drugs, patients with advanced lung cancer had a five-year survival rate of less than 1%. Although the pathogenesis of lung cancer is still unclear, scientists have found that patients have multiple lung cancer driver genes in their tumors. After some patients block these genes with drugs, the patient''s life cycle can be extended by an average of 12-18 months. At present, scientists have found dozens of driver genes for lung cancer. Specific to patients, some people may only have one or two driver genes, and some people carry more than a dozen driver genes, which also causes differences in the effectiveness of targeted drug treatment. Twenty to thirty percent of patients take no targeted drugs at all.

　　Some patients with early-stage lung cancer are blindly taking targeted drugs because of fear of surgery, let alone economic losses, and may also bring about the problem of drug resistance. Targeted medicine is not a panacea, it needs a target to work. Targeted patients, taking targeted drugs, are more effective than chemotherapy, but they are currently incurable and will eventually become resistant. Just like a lung cancer patient, genetic testing found that the mutation of the EGFR driver gene has found a target, and can take the targeted drug Iressa or Tarceva. However, drug resistance usually occurs after more than a year of taking it.

　　Tumor is a complex disease caused by multiple genes and caused by multiple factors. It is a disorder in the body caused by the imbalance of the internal and external environment of the body, and the use of a targeted product cannot change the fundamental problem.
