It is accepted by most researchers that tobacco use accounts for the majority of all preventable cancers. According to the Centers for Disease Control and Prevention, cigarette smoking is responsible for 20% of the yearly deaths in the U.S. and up to one-third of all cancer deaths.

The number one killer of tobacco users is lung cancer. However, tobacco use is also related to many other types of cancers. Researchers believe that smoking damages nearly every organ in the body and can lead to cancers of the stomach, kidney, larynx, esophagus and many others.
