Lung cancer is the term applied to a family of related malignant illnesses which afflict the lungs and sometimes spread to other tissues of the body.

Lung infections may also be caused by viruses, fungi or parasites, according to the American Lung Association. Treatment for lung infections sometimes involves antibiotics, which are ineffective against lung cancer, and rest. Unlike cancer, lung infections can clear up over time, though any lung disease should be considered serious enough for medical attention.Learn more about Cancer
