Affected by long-term smoking, aging and other social factors, the incidence of lung cancer in China is increasing at an annual rate of 26.9%, lung cancer has become the first major cancer in China, overall morbidity and mortality ranked first "health killers". In recent years, the number of women with lung cancer is on the rise, and studies have shown that it may be related to kitchen cooking fumes in women's cooking habits. Kitchen fumes stimulate the eyes and throat for a long time, and can damage the respiratory cells and tissues. Liu Lunxu, director of cardiothoracic surgery, West China Hospital of Sichuan University suggested that readers at home cooking, the lampblack machine home before ignition early a few minutes off the fire after a few minutes late closing, will be one of the effective means of prevention of lung cancer.


Smoking is the first risk factor:

According to statistics, lung cancer is the highest incidence of cancer in Sichuan, Chengdu in 2011 the overall incidence of lung cancer was 58.03/10 million, higher than the national average. Due to the early symptoms of lung cancer is not obvious, the public awareness of lung cancer early detection of inadequate, nearly 80% of lung cancer patients have been found in the middle and late.


The main cause of lung cancer is smoking, environmental pollution, occupation exposure, chronic lung disease, and genetic susceptibility, which smoking is the first risk factor, more than 80% of lung cancer is thought to be caused by smoking. Smokers are 10 times more likely to develop lung cancer than non-smokers, especially those over the age of 50, smoking and smoking 20 cigarettes a day for 20 years. The risk of lung cancer in these patients is very high.


Cough, hemoptysis, chest pain or chest tightness should be alert:

At high risk for lung cancer should be alert to some of the symptoms, main symptoms of cough is more common, after symptomatic treatment did not improve after the words, we must consider the disease; followed by sputum blood, blood often appear in the sputum intermittently or intermittently; there are some less obvious symptoms such as unknown the causes of fatigue, weight loss, may also be a sign of the cancer.


There are many patients with clinical manifestations not lung symptoms, such as when some patients come because of dizziness, the results of an investigation of brain metastasis, found has reached an advanced stage; some patients because of fractures, the results of an investigation that is caused by the pathologic fracture of bone metastasis of lung cancer.


Regular medical screening to prevent


Liu Lunxu introduced, in patients with lung cancer if the tumor without metastasis and invasion, 1 cm below the tumor after the cure rate is 92%, if it is 2 cm below the no tumor invasion and metastasis, resection after cure rate is 83%, 3 cm without cancer invasion and metastasis, resection after a cure rate of 77%, all of these. Can be carried out by way of minimally invasive, to avoid the traditional thoracotomy.


Liu Lunxu said, the scientific prevention of lung cancer, annual regular physical examination screening is very important. Regular lung CT scan for high-risk groups in order to detect lung cancer in time. To prevent lung cancer, advocate a healthy lifestyle, such as not staying up late, ensuring sleep, quitting smoking, eating a balanced diet, not drinking, early treatment of chronic diseases, and so on. At the same time, to maintain an optimistic and positive attitude, even if a cancer diagnosis, should also be standard treatment, can not be abandoned or who listen to folk remedies.
