- "Calcification" Revealed by a Chest X-ray
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: On a recently completed physical examination a chest x-ray revealed
- a "calcification". My physician assured me that it was nothing to worry
- about, and I believe him. However, I am now curious as to the meaning of this
- finding. Can you please help out?

- ANSWER: Certainly, and with a compliment to you. You have performed three
- things in an admirable fashion. You had a physical, believed your doctor, and
- continued to seek information when there were questions that you decided
- needed answers. And your physician was correct, there is nothing for you to
- be concerned about. It is probable that sometime in your past medical
- history, perhaps as a child or young man, you were exposed to tuberculosis and
- became infected. However, your own body defenses were strong enough to
- conquer this infection without additional assistance. The small area of your
- lung in which the infection occurred developed a "scar," or area of healing,
- which has become impregnated with calcium salts over the years. It was this
- "calcification" that was seen on your chest x-ray. Many people carry these
- signs of victory over disease, and they are an indication that their bodies
- carry an immunity to the disease, one which you can not be passed on to others
- as it no longer exists in their systems. Tuberculosis is still seen in the
- United States today, mostly in older people or immigrants who have not been
- adequately treated. A vaccination exists to prevent tuberculosis, called BCG
- (the bacillus of Calmette and Geurin, two Frenchmen who developed a special
- strain of the bacteria in 1906 that is used to produce immunity without
- disease). However this inoculation is rarely used today in the United States
- because of the low incidence of the disease in our population. Good
- nutrition and improved health standards are probably the reasons we no longer
- see many clinical cases of tuberculosis.
