According to the latest statistics, lung cancer tops the incidence rate of all kinds of tumors in China. In the face of the fierce lung cancer, where is the best route for prevention and treatment? A pack of cigarettes a day is 10 times more likely to develop lung cancer There is a saying in the society that second-hand smoke is more dangerous than first-hand smoke. In this regard, this is the wrong view. He told reporters that the correlation between smoking and developing lung cancer is certain, compared with non-smokers, the risk of lung cancer increases 10 times for one pack of cigarettes per day, 20 times for two packs and 30 times for three packs. But not all smokers get lung cancer, only 5% will get lung cancer, this is because genetically determined, smoke is an indirect carcinogen, we have a one term converting enzyme, how much is converted is genetically determined. What is more important is the second enzyme, if the breakdown enzyme is normal it is broken down, or most of it is broken down, then the amount left in the body will be reduced, and the possibility of getting lung cancer will be reduced. If you have a genetic defect and smoke, the chance of lung cancer is 80 to 100 times higher. Since for most people it is not known whether they have such a genetic defect in their body, not smoking is one of the best ways to prevent it. To be sure, the risk of cancer from passive smoking is also high, but when comparing secondhand smoke with firsthand smoke, active smokers have a much higher rate than passive smokers, and it is not scientific to say that passive smoking has a higher chance of getting lung cancer. The incidence rate of lung cancer in Chengdu is higher than the national average. As a rule, statistics are released to the public after three years, and the latest 2011 figures show that the national incidence rate of lung cancer in 2011 was 48.32/100,000, or 600,000 people out of 1.3 billion. The overall lung cancer incidence rate in Sichuan Province was 58.03 per 100,000, which is higher than the national average. Chengdu city ranks third in the national incidence rate, after Harbin and Beijing. The reasons for the high incidence of lung cancer are, firstly, the increasing aging of the population, the elderly population in Chengdu is close to 20% of the total population of Chengdu, while the national average ratio is about 19%. Secondly, China’s smoking population is huge, with 350 million active smokers and 700 million passive smokers. There are also haze, atmospheric pollution, and increased automobile exhaust emissions, which are the main reasons for the increased incidence of lung cancer. Third, Chengdu has done a better job in lung cancer surveillance and lung cancer prevention and control alliance, and the data is more accurate. Targeted lung cancer treatment to increase survival rate of advanced stage patients? Lung cancer treatment mainly includes surgery and non-surgical treatment. Surgery is curable and the long-term survival rate of early-stage lung cancer patients can reach over 80%, mid-stage can reach 40%-50%, and many locally advanced stage can reach over 30%, so those who can be operated must be operated. Of course, not all patients are suitable for surgery, and other treatment methods are also needed. Non-surgical treatment mainly includes traditional chemotherapy and radiotherapy, and molecular targeted therapy which is now starting and will be better developed in the future. 2005, with the entry of ERSA into China, non-small cell lung cancer treatment officially entered the era of targeted therapy. Among all patients with advanced lung cancer, the one-year survival rate used to be only 25%. Due to the application of molecular targeted drugs for lung cancer, the one-year survival rate of internal lung cancer treatment has increased to 35%, and the two-year survival rate has increased from 0% to 5% now, especially the benefit population is more after using single targeted therapy, which gives real benefits to patients.
