Lung Cancer is one of the most preventable of all malignancies. Most cases, the majority of medical experts agree, are caused by smoking cigarettes.
Smoking accounts for 90 percent of all lung cancer deaths. It is known that the lungs of some cigarette smokers show tissue changes before cancer appears, changes apparently caused by irritation of the lining of the bronchi-the large air tubes in the lung. This is why a heavy smoker who has been puffing away for many years but then stops smoking has a better chance of avoiding lung cancer than one who continues smoking. The evidence linking cigarette smoking and lung cancer was purely statistical, although overwhelming. Cigarette smoking has also been implicated in other kinds of lung disease, including the often-fatal emphysema, and in cardiovascular diseases.
To any sensible person, then the options would seem clear: If you don't smoke, don't start. If you do smoke, STOP, CUT DOWN, and switch to a brand low in TARS and NICOTINE- suspected but not proved to be the principal harmful agents in cigarette smoke. Other agents are known to produce lung cancers- URANIUM ORE dust or ASBESTOS FIBERS.
