Lung cancer screening hopes to save lives. But we also need to watch for possible harms

There is much to commend about Australia’s lung cancer screening program, which started on July 1.

The program is based on gold-standard trial evidence showing this type of screening is likely to reduce lung cancer deaths.

Some people will have their life prolonged due to this screening, which involves taking low-dose CT scans to look for lung cancer in people with a significant smoking history.
