Johnny Boy actually died of emphysema.
They're right though emphysema is a type of lung cancer.
Incorrect; emphysema is not lung cancer. You get emphysema when the lung tissue has been altered and you’re not able to breathe properly. This is a common disease for those who smoke, like Johnny Boy. It causes the lungs to be less flexible. Lung cancer, on the other hand, is related to cigarette smoking but it is characterized by uncontrolled cell growth in tissues of the lung.
