Malignant lung and bronchial tumors are generated especially by a long timed misuse of nicotin. If not treated they can cause an early death, that’s why a patient should do a diagnostic investigation and a therapy as soon as possible.
Depending on the type of the swelling’s fine tissue it is necessary to remove a part of the lung or even a half o fit. Every smoker should pay attention to the signals his body is sending, e.g. blood-expectorating cough or loss of weight, and, if it is the case, visit a doctor immediately.
