It is known to most of us that those who smoke have the risk of developing lung cancer. In recent studies, it has also been found that there is an increase in the number of lung cancer patients among those who never smoke in their life. There are again two types among these people. One type neither smoke nor they are addicted to any other smokeless tobacco and the other type never smoke but are addicted to smokeless tobacco including chewing tobacco and snuff.

Some Facts
