As we have already discussed that smoking is the most common cause behind the lung cancer. Almost 90% of the lung cancer cases arise due to tobacco consumption.

“Lung Cancer from Smoking” is not a one time process, it increases over the years of smoking practice and gradually leads to Lung Cancer. However, if you realize your mistake after years of smoking, you can still make a fresh start which will help you in reducing cancer risk. The relation between Smoking and Lung cancer is very clear that is “the more you smoke, the longer you smoke, the harder you smoke, the more severe lung cancer stage you face”.
