Screening for Lung Cancer
Lung cancer is one of the most common cancers and is the leading cause of cancer death in Ontario. The reason so many people die from lung cancer is that by the time it is usually diagnosed, the cancer has spread to other parts of the body or is too big. When the cancer has spread or is too big, treatment has less of a chance of working.
Cancer screening is testing done on people who may be at risk of getting cancer, but who generally feel fine.
We now have an effective and evidence-based way to check, or screen, people for lung cancer. That means we can find some lung cancers early, when treatment has a better chance of working.
