Lung cancer is the leading cause of cancer death in the U.S. One reason: It doesn't often have symptoms in its early stages, when it's easier to treat. That's why an annual low-dose CT (LDCT) screening is a lifesaving test for people at high risk for lung cancer.
Screening can help find lung cancer early, before symptoms start. That can mean more treatment options—and better outcomes.
Who should get screened?
LDCT screening is recommended for people who are at high risk for developing lung cancer. Ask your doctor about a screening if you:
• Are between 50 and 80 years old.
• Have a 20 pack-year smoking history. (For example, this means smoking a pack a day for 20 years or two packs a day for 10 years.)
• Currently smoke or you quit smoking in the last 15 years.
If all three of the criteria apply to you, it may be time to schedule your screening.
The benefits of screening are much greater for people at higher risk. So it's not recommended for people who have never smoked.
How you'll be screened
The test itself is quick and painless. During the LDCT scan, you'll lie on a table while a CT scanner takes detailed images of your lungs from different angles. The screening uses less radiation than standard CT scans, and the detailed images let doctors spot early signs of cancer. The whole process only takes a few minutes.
After your scan has been reviewed, a health care provider will go over the results with you. If they find something concerning, you might need more tests. But it's important to know that not all abnormal findings mean cancer. Your provider will guide you through the next steps if needed.
If you're over 50 and your smoking history means you're at risk for lung cancer, don't wait. Early detection could make all the difference.
