What is lung cancer screening?
Lung cancer screening uses an ultra low dose CT scan of your chest to look for early signs of lung cancer in people who have no symptoms. We offer it through the National Lung Cancer Screening Program, an Australian Government program that started on 1 July 2025.
The scan looks for small lumps in the lungs, called nodules. Nodules are common, and most are not cancer. Finding lung cancer at an earlier stage can mean more treatment options and a better chance of a cure.
The scan is quick, and there is no injection or contrast dye.
Who is eligible
You need a request for the scan from your GP, nurse practitioner or specialist. You may be eligible for the program if you:
- Are aged 50 to 70
- Have no signs or symptoms of lung cancer
- Still smoke, or quit in the last 10 years
- Have a smoking history of at least 30 pack-years
A pack-year is a packet of 20 cigarettes a day for one year, so a packet a day for 30 years comes to 30 pack-years. Your doctor will work out your pack-years with you and check that the scan suits you. You do not have to quit smoking to take part.
Once you are in the program, you can keep screening every 2 years until you turn 71, even if you quit more than 10 years ago.
