Screening & Testing: Lung Screening (113)

What is a Lung Screening

Lung screenings are recommended only for adults who do NOT have any symptoms of cancer but are at high risk, and only after consulting their medical team. The sole test to be performed is a low-dose CT Scan.


The U.S. Preventive Services Task Force recommends yearly lung cancer screenings for those with heavy smoking history of 30 pack years or more. A pack year is smoking an average of one pack of cigarettes per day for one year. For example, a person could have a 30 pack-year history by smoking 30 years or two packs a day for 15 years.

Screening Methods: 

The scan is performed by laying down on a table that moves through a donut shaped x-ray machine. The machine captures multiple images using a low dosage of radiation. The various x-ray pictures are processed by a computer to create a detailed image of the lungs. The scan is painless and is quick, (about 5 minutes).


There is no special preparation required.

Yearly lung cancer screenings are also recommended for those who currently smoke or have quit within the past 15 years, and those who are between 55 and 80 years old.
