Lung cancer can be a silent killer. For many people, this disease doesn\u2019t show symptoms until it has already spread, which makes successful treatment all the more challenging.\nVisit the UPMC Lung Cancer Screening Program website.\nThat\u2019s one reason why lung cancer remains the leading cause of a cancer death among both men and women. An estimated one in four cancer deaths is the result of lung cancer \u2014 more than those from breast, prostate, and colon cancer combined.\nEarly detection is key, particularly in people at high risk for lung cancer. To help identify lung cancer earlier in the process, you may undergo low-dose computerized tomography (CT) screening. This imaging test could help your doctor detect lung cancer before it spreads.\nCT Scans for Lung Cancer\nCT scans combine x-rays with computer processing to produce a series of cross-sectional images of the body.\nResearch suggests CT scans that use a low dose of radiation may help identify cancerous tumors at earlier stages.\nIn 2011, UPMC took part in a large landmark study that looked at the effect of low-dose CT screening on people at high risk for lung cancer. The study found that using a low-dose CT scan of the chest could help to reduce deaths from lung cancer by up to 20 percent in high-risk patients. These results were published in the prestigious New England Journal of Medicine.\nThe Right Choice? CT Lung Screening\nCould low-dose CT lung screening be right for you? Doctors may recommend this test to people at high risk for lung cancer, including those who:\n\nAre between ages 55 and 77\nHave a 30-pack per year history of smoking\nAre current smokers or have quit within the last 15 years\nAren\u2019t currently being treated for cancer\n\nThis type of cancer screening requires a prescription. Your doctor can help determine whether you fit this criteria\u00a0and whether low-dose CT lung cancer screening is right for you. You\u2019ll also want to check with your insurance carrier to confirm that this type of test is covered.\nUPMC offers low-dose CT scans as part of its Lung Cancer Screening Program.
