Oncologists gave the possible reasons due to which the lungs and bronchi, appears a malignant tumor.
Cancer is one of the most terrible diseases, in many cases, it is incurable. But still, every patient has a chance to recover, however, if the tumor was diagnosed at the early stage of development. The cancer cells usually affect the bronchi or lung tissues themselves, hence there are two types of lung cancer: Central and peripheral.
The characteristic symptom Central lung cancer that a person can find himself: a dry cough, not associated with any respiratory disease. This cough can be a long time to torment the patient, then it develops into wet with sputum. Often the Central lung cancer patient sees in the sputum blood clots. With such a symptom to put off going to the doctor extremely illogical.
Peripheral lung cancer more terrible from the point of view of what he can develop, without giving any symptoms. That is, a malignant tumor grows in the tissue of one lung and did not bother the man, but when the tumor reaches a critical size, there may be symptoms such as: tightness in the chest, fever, accompanied by severe cough. To identify the cause of these changes in the physical state, it is necessary to immediately consult a therapist, who after inspection, will likely direct the person to an oncologist.
Four main causes of lung cancer:
1. Smoking. Scientists from around the world encourage people to quit Smoking, as Smoking per day more than 20 cigarettes, a person increases the chances that his lungs will appear tumor.
2. Work associated with the production, where the air is saturated with toxic substances. For example, the production of asbestos, which has a negative impact on the respiratory system, highlighting in air the toxins.
3. Previously suffering of serious diseases of the lungs and bronchi, these include: pneumonia, chronic bronchitis, tuberculosis and so on.
4. The radiation damages the tissue of the respiratory tract, making them virtually unprotected, so cancer cells have free access to the development in the lungs and bronchi.
If you fall under at least one of the above risk groups of lung cancer, the examination must be held each year. As prophylaxis should be discontinued at least from Smoking.
