Studies in Massachusetts have found that smoking is responsible for more cancers than just cancers of the lung. In fact, according to this article in Science News 70% of all cancer deaths are smoking-related:
"This study provides support for the growing understanding among researchers that smoking is a cause of many more cancer deaths besides lung cancer," said lead author Bruce Leistikow, a UC Davis associate adjunct professor of public health sciences. "The full impacts of tobacco smoke, including secondhand smoke, have been overlooked in the rush to examine such potential cancer factors as diet and environmental contaminants. As it turns out, much of the answer was probably smoking all along."
I don't question this report, but the results seem at odds with my own personal experience. As I reflect on all the people I have known over the years who have had cancer, and the number is in the double digits, I can't think of a single one who was a smoker. It would be interesting to hear what our readers think about this. How many of the people you know who have had cancer of any kind were smokers?
