Cancer rates are higher in eastern Canada

Lung cancer is the second most common cancer in Canadian men and women in 2019.

Newfoundland and Labrador residents are most at risk of being affected by cancer, according to the latest data from Statistics Canada.

The cancer incidence rate in this province is 531.2 cases per 100,000 people. In comparison, it is 472.3 cases per 100,000 people in British Columbia, the province with the lowest cancer incidence rates in the country.

These data are taken from the Canadian Cancer Registry (CCR), but do not include data from Quebec and Nova Scotia since these two provinces did not report their data to the CCR.

Note that the data collected is for 2019 and predates the COVID-19 pandemic, which could have had an impact on cancer screening and diagnosis in the country.

In general, the incidence rates have nevertheless slightly decreased in the country, an encouraging figure for the researcher at the Atlantic Cancer Research Institute and associate professor at the Université de Moncton Sandra Turcotte.

We don't have anything very different, or alarming, from what we saw before. The numbers are still down a bit in some provinces, so that's encouraging, says Ms. Turcotte.

Sandra Turcotte holds the Canadian Cancer Society Research Chair, Researcher in Residence at the Atlantic Institute of cancer research and associate professor in the department of chemistry and biochemistry at the Université de Moncton.

According to Statistics Canada, the incidence of cancer is higher in the Atlantic provinces for all types of cancer, after taking into account variations in the age structure of the provinces and territories.

Cancer incidence is influenced by factors such as screening policies, data collection, access to health care, and lifestyle differences, which vary widely from country to country. region to region, says Statistics Canada in a news release.

Controlling for gender, cancer incidence rates are highest in Prince Edward Island for men (608 cases per 100,000 population) and Newfoundland and Labrador for women (508 cases per 100,000 people).

According to Sandra Turcotte, several factors may explain the incidence of cancer in the Atlantic provinces.

Among the factors, there is tobacco, there is also obesity – our rates are a little higher than elsewhere in the country – we have an aging population, we must not neglecting this, cancer rates increase with age, explains the researcher.

Geographical differences are observed for most of the most common types of cancer, but not all.

Lung cancer, bronchus cancer and cancer breast cancer are more prevalent in the Atlantic provinces.

However, breast cancer is more prevalent in Alberta (139 cases per 100,000 women) and Ontario (132). The lowest rates are found in New Brunswick (103) and Prince Edward Island (113).

Prostate cancer rates are highest in Manitoba (140 cases per 100,000 men) and Alberta (137) while the lowest rates are in Prince Edward Island (114) and Ontario (110).

In general, the most common cancers in men are cancers of the prostate, lungs and bronchi, and colorectal cancers.

Sandra Turcotte remains hopeful that technological advances will lead to better cancer treatments.

Research is key, says Sandra Turcotte of the Atlantic Cancer Research Institute.

For some cancers, we have made progress, for others not so much, and that is why research is extremely important. All the implementation of new technologies, sequencing allows us to do a little more customization and to try to improve our approaches, underlines Ms. Turcotte.

According to Projections from research published in the Journal of the Canadian Medical Association estimate that there will be 233,900 new cases of cancer and 85,100 deaths from cancer in 2022.< /p>
