Will a Period of not Smoking Give one Pristine New Lungs? ------------------------------------------------------------------------------ QUESTION: Assuming that all the cells in one's body die and are replaced sooner or later, can one say that after thirty years of smoking, a five to seven year period of not smoking will give one pristine new lungs? ------------------------------------------------------------------------------ ANSWER: An interesting question, but unfortunately based upon a wrong assumption. It is true that we replace all our red cells every 100 days, and that many other body cells die and are replaced in the normal process of living, but some of the damage inflicted on lungs by thirty years of smoking can never be repaired. Chronic bronchitis, emphysema and chronic airway obstructive disease are all possible outcomes of long term cigarette smoking. Smoke has an adverse effect on lung defenses and provokes a low grade inflammation which, in turn, leads to the changes in lung anatomy and function. But I don't want to take a completely negative approach to your question. It is true that if lung function is measured by certain tests in smoking individuals, and then compared to the results of the same test after a period of smoking abstinence, a notable improvement can be measured. Many of the symptoms of coughing and shortness of breath also improve considerably, as the lung cleanses itself and revitalizes after the constant irritation of smoking is removed. However, if the seeds of cancer have been sown during your thirty year experience with tobacco, stopping the habit now can not eradicate the tumor. It is nice to think of our body as being constantly renewed and repaired, but it is mortal, and with time begins to show the signs of wear and tear that we inflict upon it. Good health habits allow the body function at its best, and offer the best hope for a long life. ---------------- The material contained here is "FOR INFORMATION ONLY" and should not replace the counsel and advice of your personal physician.
