Lung cancer - Causes And Risk Factors

Prevention of lung cancer

Prevention of lung cancer

Prevention of lung cancer, In cancer the healing ability is the greater the sooner a tumor is discovered. If this were possible at an earlier stage, up to 70% of patients could survive five years and more. However, since early lung cancer does not cause any discomfort, it is almost always discovered by chance. If symptoms and symptoms are caused by a lung cancer, an advanced disease stage is usually present. In contrast to other types of cancer, there are also no regular preventive examinations.

This is due to the fact that tests such as blood tests on tumor markers or sputum analyzes (examination of ejection) are not reliable enough. On the other hand, it has not yet been possible to demonstrate that a screening, for example by means of X-ray examination of the lungs, actually offers an advantage.

The annual examination of risk patients, ie severe smokers, with an annual low-dose computed tomography has not yet been able to be used as an early detection measure. A large US study showed that lung cancer mortality can be reduced by about 20%. However, these results have now been somewhat relativized. According to this study, only 300 patients are infected with the disease, and death by lung cancer can be avoided with suitable treatment methods. In addition, there was a high rate of false-positive findings, that is, the CT revealed a cancer suspicion, although no tumor was present. These misdiagnoses do not only mean a considerable psychological burden, they also lead to further investigations, which can carry certain risks. In Germany there is currently no screening program for lung cancer.

Never Too Late: Stop Smoking!

Lung cancer is one of the few types of cancer whose main risk factor is doubtless fixed: smoking . It is estimated that 80 to 90% of all malignant lung tumors are attributable to smoking, since cigarette smoking alone contains more than 4,000 different chemical constituents, of which approximately 50 are found to cause cancer. The same is true for all other tobacco products. Experts estimate that about every tenth smoker will develop a lung carcinoma during his lifetime. The number of cigarettes smoked every day as well as the number of smoking years is decisive.

In addition to the active, passive smoking also increases the risk of developing lung cancer.
