ASBESTOS AND SMOKING

Asbestos exposure and smoking have something in common: they are bad news for your body, especially your lungs, and they are even worse when they happen together. If you have an asbestos-related disease, quitting smoking can help slow the progression of your disease, make is easier for you to breath, improve blood flow, and decrease stress on your heart. But quitting smoking is also important to cut your risk of getting cancer in the future, whether you are sick today or not.

You probably know that we are all exposed to things that can cause cancer. What you may not know is that sometimes combinations of exposures are more dangerous than the sum of the individual exposures. For example, it is generally accepted that asbestos exposure can make someone 5 times more likely to get lung cancer. Smokers are approximately 10 times more likely to get lung cancer. But if you are a smoker and were also exposed to asbestos, your risk is not 15 times higher—it’s about 50 times higher! Instead of adding the increased risks created by asbestos and smoking, the risks are multiplied when they occur in the same person. This is called a synergistic effect.

There is nothing that can be done about the increased risk of cancer caused by asbestos exposure. The asbestos fibers stay inside the body even when you are no longer exposed to asbestos. But something can be done about the risk of cancer caused by smoking. According to the American Lung Association, if you quit smoking today, in ten years your increased risk of lung cancer attributable to smoking would be half that of a continuing smoker. Your risk of heart disease, stroke and several other cancers would also decrease substantially.

Anyone concerned about health should stop smoking, but if you have a history of asbestos exposure and certainly if you already have an asbestos-related disease, the danger of continuing to smoke is even greater for you—and so are the benefits of stopping.
