Approximately 170,000 new cases of lung cancer are diagnosed each year. It is the most deadly cancer, causing more deaths than skin cancer, breast cancer, prostate cancer, and colon cancer combined.
You can cut your risk of lung cancer:
- 85% – by not smoking. Cigarette smoke contains more than 4,000 different chemicals, many of which are proven carcinogens.
- 55% – if you quit smoking. However, former smokers always remain at higher risks for developing lung cancer than non-smokers.
- 22% – if you limit your exposure to radon, an invisible, odorless gas that occurs naturally in soil and rocks.
- 22% – if you limit your exposure to second-hand or passive smoke. Choose restaurants that honor a strict no-smoking policy.
- 15% – if you strictly limit your exposure to industrial and organic substances including air pollution, asbestos, uranium and diesel fuels.
Lung cancer risk factors include:
- tobacco use
- environmental tobacco smoke (second hand smoke)
- radon and asbestos
- exposure to certain industrial substances, such as arsenic
- some organic chemicals
- radiation exposure from occupational, medical and environmental sources
- air pollution
Non-smokers diagnosed with lung cancer are more likely to be women than men.
Studies show that given the same level of lifetime exposure to cigarette smoke, the risk for developing lung cancer is higher in women than men, especially at lower levels of exposure to cigarette smoke.
Risk reduction becomes evident within five years of abstinence from smoking. With further abstinence the risk continues to decline, although former smokers remain at higher risk than people who never smoked.
Since 1964, when the Surgeon General released the first U.S. report on smoking and health, more than two million American smokers have died from smoking-related lung cancer.
