Lung cancer (bronchial carcinoma) is a malignant disease of bronchial or pulmonary tissue. It is one of the most common tumors, ranking just behind breast, prostate and colon cancer.
Lung cancer risk factors
- in 90% of the cases: smoking
- much rarer inhaled rhadon, asbestos oder chromion
- passive smoking
- family history
Symptoms such as blood coughing and chronic bronchitis with hoarseness can indicate an already advanced tumor growth with low healing chances.
In the early stages, however, the disease is often curable in about half of the cases. Warning symptoms are usually absent. At this stage the disease is found either by chance or by screening examinations.
Lung cancer diagnostics and screening
Currently the best investigation method is the computed tomography which, in contrast to the conventional chest x-ray, already detects changes in the range of millimeters.
In the context of prevention, ultra-low-dose computed tomography is now well justifiable as an individual screening with 70% reduced radiation exposure.
This screening can be recommended for those who either smoke actively or passively, who have a familial risk of a parent or who are exposed to asbestos professionally.
