Lung Cancer Screening | LDCT

The MaineHealth Cancer Care Network offers comprehensive lung cancer screenings to test people at high risk for lung cancer. The screening is appropriate for older adults with a history of smoking cigarettes. The screening looks for lung cancer in its early stages before it can do harm.

What is the Lung Screening?

Known as the LDCT, the test uses low-dose computed tomography (LDCT), or a CAT scan, to look for lung cancer at a very early stage. The LDCT scan is painless and takes less than five minutes.

LDCT Scan is for People with a Long History of Smoking.

The LDCT scan is not for everyone. A yearly lung cancer screening is recommended for older adults who are current smokers and who used to smoke. The screening may be right for you, if you:

  • Are between 55 and 77 years old

  • Have no signs or symptoms of lung cancer

  • Currently smoke or have stopped smoking in the last 15 years or less, and

  • Have a history smoking a pack of cigarettes daily for 30 years, or two packs a day for 15 years.    

If you meet all three criteria, you may benefit from lung cancer screening.
