Lung Cancer Screening

Lung cancer screening is available to those with a long history of smoking. Screening makes it possible to diagnose patients at an earlier stage compared to waiting for symptoms to appear. And the earlier it’s found, the easier it is to treat effectively. Let's take a look at who qualifies and what the test is like.
Who Qualifies for Lung Cancer Screening?
The following recommendations are in place for lung cancer screening from the the American Academy of Family Physicians (AAFP).
Age 50-80: Annual lung cancer screening with a low-dose CT scan (LDCT) if you are:
-
In fairly good health, AND
-
Currently smoke or have quit in the past 15 years, AND
-
Have at least a 20 pack-year smoking history.
What is a pack-year?
This is the number of packs of cigarettes per day multiplied by the number of years smoked. For example, someone who smoked 2 packs a day for 10 years [2 x 10 = 20] has 20 pack-years of smoking, as does a person who smoked 1 pack a day for 20 years [1 x 20 = 20].
What Test is Used for Lung Cancer Screening?
A low-dose CT scan of the chest is used to screen for lung cancer because it's safe, painless, and is able to detect more than X-rays. The CT technology can detect areas of concern that may not be fully developed yet into something that can be seen on an x-ray. Low-dose CT scans take just a few minutes and are performed outpatient, meaning they do not require hospital or clinic admission.Patients Have a Better Prognosis When Lung Cancer is Found Earlier
Should Non-Smokers Get Screened for Lung Cancer?
Even if you are exposed to second hand smoke, the The U.S. Preventive Services Task Force does not recommend lung cancer screening for people who have never smoked. That’s because the possible harms of repeated radiation exposure from the low-dose CT scans outweigh the possible benefit of detecting lung cancer since it's less likely to occur among nonsmokers. However, nonsmokers should be aware of other risk factors that can lead to lung cancer as well as lung cancer symptoms because they can be diagnosed with lung cancer.
