Background


Lung cancer is the leading cause of cancer deaths in both men and women. Less than 18% of patients survive 5 years or more. If lung cancer is diagnosed early (through screening) and treated early before it spreads outside the air passages, over 77% of patients survive 5 years or more. Low dose computed tomography, often simply called "CT scan", can pick out tiny cancers that are not visible by previous tests. 

The B.C. Lung Screen Trial, a study led by Dr. Stephen Lam (Respiratory Medicine), Dr. John Yee (Thoracic Surgery) and Dr. John Mayo (Radiology) at the Vancouver General Hospital in association with the B.C. Cancer Agency, aims to improve lung cancer survival rates by using early detection low dose CT scanning which has been shown to reduce lung cancer mortality by 20% in a larger randomized clinical trial.
