Trends in Colorectal Cancer

Colorectal cancer incidence rates between 1983 and 2000 were relatively stable in men and declined slightly in females. In both sexes, the incidence rate has declined significantly (0.8% per year) since 2000.

Between 2001 and 2007 for males and between 1998 and 2007 for females, overall mortality rates declined significantly. The rates declined, on average, by at least 2% per year since 2003 in males. In men and women combined, colorectal cancer is the third most common cancer at 13%.

Mortality rates continue to decline in both sexes—by 2.6% per year in males since 2003 and 1.8% per year in females since 1998. Colorectal cancer has a significant impact on mortality for men and women combined, with 12% of all cancer deaths expected.

Screening for colorectal cancer can reduce both incidence (by identifying and removing precancerous polyps) and mortality. Screening has already been occurring in several provinces, which may partly account for the decline in mortality, though screening rates are low. All provinces have announced or have started implementing organized screening programs.

Canada Wide Statistics 2012

This year, an estimated 23,300 Canadians (13,000 men and 10,300 women) will be diagnosed with colorectal cancer and 9,200 (5,000 men and 4,200 women) will die from it.

On average, 448 Canadians will be diagnosed with colorectal cancer every week and 176 will die from the disease every week.

The highest colorectal cancer incidence rates among men and women occur in Newfoundland and Labrador. For women, high rates also occur in Prince Edward Island and Nova Scotia. The lowest rates for both sexes are in British Columbia.
