What is a pack-year?
A pack-year is a measure of how much a person has smoked over a period of time. It is simply the number of packs of cigarettes smoked per day multiplied by the number of years the person has smoked.
If you have the equivalent of a 30 pack/year history or more, consider getting a CT Lung Cancer Screening. This exam has the ability to detect lung cancer in its earliest stages when it is most treatable.
