Facts About Lung Cancer

Lung cancer remains the leading cause of cancer death in Canada and is now the second most commonly diagnosed cancer in both men and women. An estimated 32,900 Canadians will be diagnosed with lung cancer this year, and approximately 19,300 will die from the disease—more than breast, prostate and colorectal cancers combined.

While advances in research and treatment over the past decade have improved survival, too many people are still diagnosed at a late stage, when the disease has already spread and outcomes are significantly poorer.

Importantly, lung cancer now affects more women than men in Canada. This shift underscores a changing and often misunderstood risk profile, reinforcing the need for greater awareness, earlier detection, and more equitable access to care.1
