Cancer touches nearly every family in Canada. It is the leading cause of death in the country, and it is estimated to cost the health care system, patients, and families nearly $37.7 billion every year—from hospital care and medications to lost wages, reduced productivity, and out-of-pocket expenses. Yet up to 40% of cancer cases could be prevented through changes in lifestyle and environmental factors—a powerful reminder that prevention strategies, alongside early detection and research, can save lives and reduce the burden of cancer.
