Prevention: Lung Cancer

Considering that 90 percent of lung cancers are believed to be the result of tobacco use, the American Cancer Society strongly recommends avoiding tobacco or exposure to tobacco as the most important step a person can take to help reduce his or her risk of lung cancer.

Additionally, many studies have shown that the risk of lung cancer is lower among both smokers and nonsmokers who consume at least five servings of vegetables and fruits a day. Although healthful eating may reduce the risk of lung cancer, the risks from tobacco smoking, chewing tobacco, and snuff remain substantial.
