Lung Cancer
Lung cancer: the leading cause of cancer death.
Lung cancer accounts for almost 25% of cancer deaths. And although it begins in the lungs, it can spread to other parts of the body. In many cases, lung cancer has no symptoms until it’s in the later stages, when it’s more harmful and difficult to treat.
Thankfully, there’s now a screening to help detect it early on, when it’s most treatable. Called a low-dose CT scan, this screening can reduce the risk of fatality by 20%.

Screening
When you should be screened.
Smoking is the #1 risk factor for lung cancer, though not all lung cancers are caused by smoking. Currently, lung cancer screenings are recommended only for smokers or former smokers who fit certain criteria.
Men and women 50-80 who:
- Smoke or have smoked a pack a day for 20 or more years, or 2 packs a day for 10 or more years
- Currently smoke or quit smoking within the past 15 years
Screening should be discontinued once a person:
- Has not smoked for 15 years
- Develops a health problem that substantially limits life expectancy or the ability or willingness to have curative lung surgery
