2. Bronchitis is inflammation
of the mucous membranes
of the bronchi.
There are two basic types
of bronchitis - acute and
chronic.

3. Acute bronchitis is characterized by the
development of a cough, with or without
the production of sputum.

4. It often occurs during the course
of an acute viral illness such as
the common cold or influenza.

5. Chronic bronchitis, a type of chronic
obstructive pulmonary disease, is
characterized by the presence of a
productive cough.

6. Chronic bronchitis most often develops
due to recurrent injury to the airways
caused by inhaled irritants.

7. Bronchopneumonia is a common
inflammation of the lung.
Inflammation starts in bronchioles,
and spreads to the peribronchiolar
alveoli and alveolar ducts.

8. The result is that the inflammatory
changes lead to the localized
inflammatory consolidation in
bronchioles and their surrounding
alveoli of the lungs.

9. Most of the time, bronchopneumonia is
caused by bacterial infection.

10. It often occurs in human due to
the lower body resistance and
the impaired defense function
of the respiratory tract.

11. Cough and coughing
up phlegm are both
the main symptoms of
bronchopneumonia.
Having fever and shortness
of breath are also common.

12. Lung cancer is a disease that consists of
uncontrolled cell growth in tissues of the lung.

13. The main types of lung cancer are
small-cell lung carcinoma and non-small-
cell lung carcinoma.

14. The most common cause of lung cancer is
long-term exposure to tobacco smoke.
There are non-smokers who also suffer
from lung cancer.

15. Lung cancer may be seen on chest radiograph
and computed tomography. The diagnosis is
confirmed with a biopsy.

16. Treatment and prognosis depend upon
the histological type of cancer, the stage
and the patient's performance status.

17. Possible treatments include surgery,
chemotherapy, and radiotherapy.
Survival varies, depending on stage,
overall health, and other factors.
