Emphysema and lung cancer are 2 condition related to smoking. (A)
Emphysema is described has a Chronic obstructive pulmonary disease (COPD) and is a combination of lung damage and mucous production that makes it hard to breathe. This is a chronic condition caused by damage to the alveoli air sacs in the lung. When the lungs are exposed to cigarette smoke, causes excess mucus production due to the destruction of lung tissue in the smaller airways. This makes them unable to hold there structure properly and the alveoli becomes damaged and inefficient in the absorption and transportation of oxygen and carbon dioxide in and out the body. This is a chronic condition that worsens over time; the symptoms may not be noticeable until they are severe enough to interrupt daily activities. A person with this condition would feel tired, shortness of breath, chronic cough with or without mucus, wheezing and chest tightness. Lung cancer is the uncontrolled growth of abnormal cells in the lung. Sometimes the cells can dysfunction and form tumours that clog up the lung and make it stop functioning. Because of the large size of the lungs, cancer may grow for many years, undetected, without causing symptoms. The most common symptom of lung cancer, a persistent cough, can often be mistaken for a cold or bronchitis. This makes lung cancer difficult to diagnose and when it is found out, it usually is in the late stage. It is a very aggressive type of cancer. (B)

Lung cancer and emphysema are two distinct diseases that cause damage to the lungs. Emphysema does not, however, lead to lung cancer. The relationship between these diseases is instead one based upon mutual risk factors, namely smoking. A person with emphysema is ultimately at greater risk of developing lung cancer. This is because smoking complications can extend from lung tissue damage (emphysema) to lung cell damage (cancer).

Emphysema is a chronic obstructive pulmonary disease marked by lung tissue destruction and...
