Cancer incidence and mortality rates are declining across Canada, offering signs of progress in prevention and treatment, but new data shows certain cancer types are on the rise, underscoring ongoing public health challenges.
A new study published in the Canadian Medical Association Journal estimates more than 250,000 new cancer cases and nearly 90,000 cancer-related deaths in Canada in 2026, reaffirming cancer as the country’s leading cause of death.
Researchers found that rates are decreasing for roughly two-thirds of cancer types, including lung, colorectal, bladder cancer and leukemia, reflecting improvements in screening, prevention and treatment.
However, lung cancer remains the most commonly diagnosed cancer and the leading cause of cancer-related deaths, accounting for one in five fatalities. It is expected to result in approximately 32,900 new cases this year.
At the same time, several cancers are becoming more prevalent, including cervical, head and neck, pancreatic, uterine cancers and melanoma. Experts warn that some of these, particularly cervical and head and neck cancers, are closely linked to HPV and are largely preventable through vaccination.
The study also highlights a concerning rise in early-onset cancers, particularly colorectal and breast cancer among individuals under 50, prompting calls to expand screening programs to younger age groups.
While overall trends point to progress, experts stress that continued investment in prevention, early detection and treatment remains critical as nearly 42 per cent of Canadians are expected to be diagnosed with cancer in their lifetime.
