Interesting Fact:

About 163,000 Americans die each year from lung cancer. This is greater than deaths caused by the next four cancers combined. With each puff, a cigarette smoker inhales over 60 known or suspected cancer-causing agents (carcinogens)—including polyaromatic hydrocarbons (PAHs), nitrosamines, and heavy metals.
Most of the deaths from cancers (90%) are due to cancer cells spreading and establishing colonies in other parts of the body.
