163flzx.com/ no obvious symptoms of early lung cancer, only a small number of patients with lung cancer due to tumor stimulation of bronchial mucosa, irritating cough may be early symptoms such as cough and the season that , independent of time and medication. Most of all lung cancer patients with advanced lung disease to appear cough, hemoptysis and other symptoms.
origin of lung cancer confined to the basement membrane of bronchial epithelial cancer in persons known as carcinoma in situ swelling, may apply to the bronchial lumen and / or adjacent lung tissue growth and through blood or lymphatic spread of bronchial metastasis.
which lung cancer accounted for about 25% of primary lung cancer, more than in the lung Department of the surrounding, close to the pleura, cancer and smoking are not closely related, often in a chest X-ray, CT scan was found. Adenocarcinoma Although slow growing, but some patients with hematogenous metastasis occurs, the general performance of the brain in transfer of symptoms, primary lung cancer was found.
According to statistics, more than Qicheng when newly diagnosed lung cancer patients to the middle and late, which is bad treatment of lung cancer the most important reasons. support Xiuyi introduced in medicine, lung cancer
is divided into four phases, ? or ? 5-year survival rate for patients less than 20%, most patients will die within 2 years of illness. ” however, if the tumor can be found in stage ?, through surgery, the patient may recover up to 70% 5-year survival rate of -80%. If, after formal treatment and regularly followed up, as fully to life and health of people. however, this proportion is only about 20% clinical. even ?, 5-year survival rate after treatment can reach 50%. “Professor Zhi Xiuyi said not without regret.
This is because the tumor growth and metastasis takes time, if there is no transfer of timely detection and proper treatment, can certainly improve the cure rate of lung cancer. “But our current work on early screening for lung cancer is still lagging behind, it can be said is still blank. “Zhi Xiuyi stressed.
lung cancer screening to note:
First, for high-risk groups.
1. Smoker. Smoker lung cancer the risk is 9-10 times the non-smokers, heavy smokers or even as high as 10-25 times. In addition, if the home is often a “smoky”, even if you do not smoke, also a high risk .
2. regular contact with pollutants in the staff. traffic police, long a large number of teachers with chalk, work exposure to asbestos, ionizing radiation, microwave radiation people would be much higher risk of lung cancer.
3. people who had lung disease.
4. a family history of cancer in people.
Second, the screening to choose the right equipment. low-dose spiral CT can be more accurate screening for lung cancer.
