Does lung density increase shadow must be cancer

Lung density is not necessarily cancer. Lung

density is an imaging finding that may be caused by inflammation of the lungs, which may lead to increased local secretions when inflammation stimulates lung tissue, resulting in extensive exudation in the lungs. Second, tuberculosis patients may also show lung density due to fibrosis or calcification of lung tissue stimulated by Mycobacterium tuberculosis. Of course, this situation does not rule out cancer caused, such as lung cancer, due to high tumor density, so take imaging examination may appear lung density increased shadow. So simply appear lung density increased shadow and can not be clear whether cancer, it is recommended to go to the hospital in time to take further examination to be clear.
