Dr. Sanderson explains the connection between smoking and lung cancer.
Smoking probably is responsible from between 85 and 90 percent of all malignancies, that’s active smoking. Passive smoking probably contributes some lung cancer in individuals who have not been smoking, not been smokers. But there’s probably 10 percent of the people who develop lung cancer but we really don’t have a good explanation and they are just unfortunate that they did not have any behavior problems that have contributed to their ailment.
