The facts are conclusive, smoking causes both lung cancer and

emphysema. Ellen Brown's article Waging War On Lung Cancer and Carol

Lewis's article Causes Of Emphysema prove that smoking cigarettes cause

both lung cancer and emphysema. Although both diseases are treatable,

neither is curable, both inevitably consume a patient with unbearable

suffering and a devastating outcome. The warning signs for lung cancer

usually appear when the disease has advanced to a phase that is

incurable. The diagnosis for emphysema is often given after a patient

has noticed a considerable problem with their ability to take a full

breath thus permanent damage is already done to the lungs. Cigarette

smoke contains thousand of known carcinogenic agents that are inhaled

directly into the lungs. The human body cannot function without the

brain, and the brain cannot function without oxygen. By flowing through

the lungs, blood can exchange used oxygen and pick up fresh oxygen that

is carried to the brain. By replacing the oxygen that you breath with

cigarette smoke, you are making air exchange difficult and inefficient.

Eventually the Alveoli (the little sacs inside the lungs where ai

alveoli are completely destroyed, emphysema patients suffer from a decreased capacity within the lung. X-Ray and CAT Scan are also used when diagnosing emphysema, however airflow and perfusion are also measured with the respected devises. Unlike the dark
