Smoking - harm to health. Smoking - the cause of lung cancer

If you smoke or smoked before, you may worry about their risk of contracting "terrible disease"?
Currently, there are data showing that CT scanning of the lungs may reduce the likelihood of lung cancer.
In a large study (NLST), compared informative CT and X-ray screening for lung cancer of the lungs. To observe picked group of heavy smokers who smoked a pack of cigarettes a day and so for thirty years, their age 55 -74 years. All program participants underwent CT scanning light 2 times a year in the first year, followed a year later, and so within five years.
This study demonstrated that CT scans have helped them high in early detection of disease and reduce mortality by 20% compared with the group, which conducted an X-ray light.
Thus, our preliminary data indicate the benefit of CT scan compared with the X-ray study of the lungs of smokers.
The proposed model is similar to those used today for breast cancer screening (mammography), cervical cancer (cytology coleitis), colon cancer (colonoscopy).
Confirmation of the effectiveness of this approach was the reduction in mortality, because so are detected at an early stage when the tumor is small and very small size and were conducted in a timely surgical treatment.
CT scans can detect changes in 20-60% of smokers - residual effects of inflammation and other "not carcinogenic". Sensitivity of the method can detect suspicious for cancer education and then spend up to examination.
CT scan has a small dose of radiation, comparable to mamaografiey.
Results of the study (NLST) will change the currently existing approach to diagnosis and early visualization of cancer in mind the real benefits of this research.
You can discuss your potential risks with the doctor as a precautionary approach is very important in the way of reducing the risk of getting cancer.
