The Colorectal Cancer Association of Canada (CCAC) has reviewed the 2015 Canadian Cancer Statistics issued by the Canadian Cancer Society, Statistics Canada, the Public Health Agency of Canada and the Provincial/ Territorial Cancer Registries Specifically, we have summarized the statistics concerning colorectal cancer. We have presented this information in a comprehensive manner but should you wish to view the publication concerning all statistics, it can be found on our website at www.colorectal-cancer.ca in the Cancer Stats section under Just The Facts or at www.cancer.ca

Colorectal Cancer Stats

Starting from the mid-1980s, incidence rates declined for both sexes until the mid-1990s (although this decline was more prominent for females). Incidence rates then rose through 2000, only to decline slightly thereafter, most likely due to increased use of colorectal cancer screening, which can identify and remove precancerous polyps, which can in turn reduce incidence. The decline in colorectal cancer incidence rates appears confined to older adults as rates are increasing among young adults under the age of 50 years in Canada and in the United States. Diabetes may also increase risk for colorectal cancer. As of 2014, nine provinces had organized screening programs available, and the remaining province has announced the intention to implement one. Participation rates vary within and between the existing organized programs and do not meet the target of 60%. Colorectal cancer is linked to several modifiable risk factors including obesity, physical inactivity, consumption of red and processed meat and smoking.

The CCAC is emphasizing more than ever the importance of primary prevention and timely screening. The CCAC recommends daily regular physical exercise and maintaining a healthy body weight, smoking cessation, reducing alcohol consumption, a healthy diet low in red meat consumption and high intake of vegetables, legumes, fruit and grains. (See our Risk Factor Section to determine what you can do to reduce your risk of getting colorectal cancer.)

If you are between the ages of 50-74 and are of average risk, it is important that you be screened at least every two years with a fecal occult blood test (FOBT) or fecal immunochemical test (FIT). A colonoscopy may be appropriate in certain circumstances and in particular it may be influenced by your history and your family history. It is, therefore, important to discuss your screening plan with your physician.

Prevalence

Among Canadians alive on January 1, 2009, just over 810,000 had been diagnosed with cancer in the previous 10 years. This number represents approximately 1 in 41 Canadians or 2.4% of the Canadian population. More specifically, in the 10 years prior to January 1, 2009, among those alive, 1 in 297 males and 1 in 351 females had been diagnosed with colorectal cancer.

As of 2009 there were approximately 105,195 individuals (56,650 men and 48, 545 women) with colorectal cancer who were diagnosed in the 10 previous years i.e. 1999-2009.

New Cases

In 2015, 1 in 14 men and 1 in 16 women will be diagnosed with colorectal cancer. This amounts to approximately 25,100 (about 14,000 (56%) men and 11,100 (44%) women) Canadian new cases of colorectal cancer.

In comparison to the total cancer figures for Canada, for men the incidence of colorectal cancer represents 13.9% of all new cancers and for women it represents 11.5% of all new cancers. In males, colorectal cancer is now the second most common cancer followed by lung cancer, each accounting for approximately 14% of all new male cases. In females, lung cancer is the second most common cancer, representing 14% of all new female cases followed by colorectal cancer representing approximately 12% of all new female cases.

  • 10 new cases will be diagnosed this year between the ages of 0-19
  • 80 new cases will be diagnosed this year between the ages of 20-29
  • 310 new cases will be diagnosed this year between the ages of 30-39
  • 1,100 new cases will be diagnosed this year between the ages of 40-49
  • 3,700 new cases will be diagnosed this year between the ages of 50-59
  • 6,700 new cases will be diagnosed this year between the ages of 60-69
  • 7,000 new cases will be diagnosed this year between the ages of 70-79
  • 6,200 new cases will be diagnosed this year over the age of 80

Deaths

This year there will be approximately 9,300 Canadians who will die from the disease (about 5,100 (55%) men and 4,200 (45%) women).

Colorectal cancer is the second most likely cause of death for males with a 1 in 29 chance of dying from it. It is the third most common cause of death for females with a 1 in 32 chance of dying from it. The death rate from colorectal cancer continues to decline for both men (2.5% per year since 2004) and women (1.8% per year since 2001). This is likely due to improvements in treatments (particularly chemotherapy). The declines in colorectal cancer death rates are consistent with a relatively large contribution from screening and with a smaller impact of risk factor reductions and improved treatments. In Canada, higher colorectal cnacer death rates have been seen in areas of lower income despite universal Access to healthcare. Physical activity is associated with a reduction in colorectal cancer.

Colorectal cancer mortality rates are highest in Newfoundland and Labrador for both males and females (which also has the highest incidence rate of colorectal cancer for males and females).

0.16% of the deaths from colorectal cancer will be individuals between the ages of 20-29.

0.6% of the deaths from colorectal cancer will be individuals between the ages of 30-39.

2.6% of the deaths from colorectal cancer will be individuals between the ages of 40-49.

10% of the deaths from colorectal cancer will be individuals between the ages of 50-59.

20.6% of the deaths from colorectal cancer will be individuals between the ages of 60-69.

26% of the deaths from colorectal cancer will be individuals between the ages of 70-79.

39.7% of the deaths from colorectal cancer will be individuals over the age of 80 years.

The Relative Survival Ratios (RSRs) for colorectal cancer range from 60% to 62% in all provinces except Ontario (67%).

RSRs for colorectal cancer are consistent at 68% among people diagnosed between the ages of 15 and 69 years; RSRs then decrease with advancing age.

Survival improvements in prostate and colorectal cancers are due to increased use of Screening and early detection that have helped identify cancers at a treatable stage.

Geography

The incidence of colorectal cancer in Canada is highest for men and women in Newfoundland and Labrador. For women, high rates are also reported in Nova Scotia, Prince Edward Island, and Manitoba. The lowest rate of incidence for both men and women are in British Columbia.

THE FUTURE 2028-2032

By 2028 -2032 it is estimated that colorectal cancers will increase to 35,015 new cases from what was 19, 630 in 2003 -2007. It is forecast to be more prevalent the lung cancer in men by 2018- 2022.

It is projected there will be a net increase in prevalence from 2015 to 2030 with FIT due to the detection of cancers at earlier stages and improved survival among patients.

Between 2015 and 2030, a biennial FIT screening program with a participation rate of 30% could lead to 21,000 cumulative deaths averted compared to 40,000 cumulative deaths averted with a participation rate of 80%.
