Lung cancer screening is a way to find some lung cancers early, before a person has any symptoms of the cancer.
Lung cancer screening may help those who have the highest risk for lung cancer—people 50 to 55 and older who are or were heavy smokers. For most people, who aren't at increased risk, screening for lung cancer probably isn't helpful.
Screening won't prevent cancer. And it may not find all lung cancers. Lung cancer screening may lower the risk of dying from lung cancer in a small number of people.
Lung cancer screening is recommended for people who are or were heavy smokers. That means people with a smoking history of at least 20 or 30 pack years. A pack year is a way to measure how heavy a smoker you are or were.
To figure out your pack years, multiply how many packs a day on average (assuming 20 cigarettes per pack) you have smoked by how many years you have smoked. For example:
Experts agree that screening is for people who have a high risk of lung cancer. But experts don't agree on what high risk means. Some say people age 50 or older with at least a 20-pack-year smoking history are high risk. Others say it's people age 55 or older with a 30-pack-year history. Experts may also have other rules about who should be screened. For example, here is the guideline from the U.S. Preventive Services Task Force (USPSTF), which recommends lung cancer screening if:
The USPSTF also recommends that you no longer need lung cancer screening if you have not smoked for 15 years or if you have a serious health problem.
