No it is not a cancer. Emphysema is a lung disease that reduces the ability of the lungs to expel air, a process which depends upon the natural rubber-band-like quality or elastic properties of the lungs. Damage occurs to the tiny airways in the lungs called bronchioles. Bronchioles are joined to alveoli, tiny grape-like clusters of sacs in the lungs where oxygen from the air is exchanged for carbon dioxide from the body. The elastic properties of the lung reside in the tissue around the alveoli.
I have just recovered from double pnomonia and have been told I have infazema
Emphysema is a lung disease not a cancer. In emphysema, the walls between the air sacs (alveoli) are destroyed and the lung tissue is weakened. Normally oxygen from the air goes into the blood through these air sacs. But as the air sacs become damaged, the lung has less surface area. This interferes with the movement of oxygen from the air into the blood. So less oxygen passes into the blood of people with emphysema. Emphysema causes shortness of breath, cough and wheezing (squeaky sound when breathing).
Well is it a form of cancer
It isn't cancer, it is a disease. My grandma had it. It can be controlled but the only other option is a lung transplant, once it gets very bad. My grandma has just had one and it apparently went great!
