Projected estimates of cancer in Canada in 2022

Abstract

The impact of cancer on the Canadian population and health care systems is substantial. Cancer is the leading cause of death in Canada 1,2 and previous estimates have shown that 43% of all people in Canada are expected to receive a cancer diagnosis in their lifetime. 3 With an aging and growing population, the number of new cancer cases and deaths in Canada is also increasing. 4 In addition to its impact on health, cancer is costly. The economic burden of cancer care in Canada rose from $2.9 billion in 2005 to $7.5 billion in 2012, annually. 5 Given the considerable health and economic impact of cancer in Canada, comprehensive and reliable surveillance information is necessary for identifying where progress has been made and where more attention and resources are needed. To meet these needs, the Canadian Cancer Statistics Advisory Committee, in collaboration with the Canadian Cancer Society, Statistics Canada and the Public Health Agency of Canada, produces the latest surveillance statistics on cancer in Canada.Cancer data often lag the current date by several years, owing to the time associated with collecting, verifying and analyzing the data. Short-term cancer incidence and mortality rates can be projected by extrapolating past trends to estimate future trends, using statistical models. These short-term projections provide a more up-to-date estimate of the cancer landscape in Canada. Incidence and mortality counts, along with age-standardized rates, provide a picture of the impact of cancer in Canada, which is essential for resource planning, research and informing cancer-control programs.Canadian Cancer Statistics 2021 3 provided detailed estimates of cancer incidence, mortality and survival in Canada by age, sex, geographic region and over time for 22 cancer types. 3 Here, we provide updated estimates of the counts and age-standardized rates of new cancer cases (incidence) and cancer deaths (mortality) expected in 2022 by sex and province and territory, for all ages combined.

The Epidemiology of Breast Cancer

“…Nevertheless, the Canadian BC incidence has increased from 116.3 cases/100,000 in 1984 to 129 cases/100,000 in 2018 (49). The expected number of new BC cases in Canada is 28,600, which will make up 25% of all new cancer cases in Canadian women in 2022 (50).…”

“…According to the Canadian Cancer Society, BC became the most common cancer in Canadian women (excluding non-melanoma skin cancers) and was the second leading cause of death from cancer in 2021 (52). In 2022, Canada is expected to have 15,203 BC-related deaths, with a 5-year survival estimate of 76% (50).…”

The Impact of Organised Screening Programs on Breast Cancer Stage at Diagnosis for Canadian Women Aged 40–49 and 50–59

“…Treatment advances for breast cancer may raise questions about the relative importance of screening. Yet despite these advances, BC is still expected to be responsible for a quarter of all new cancer diagnoses in Canadian women and 14% of all cancer deaths in women in 2022 [ 3 ]. BC is the leading cause of non-accidental death in women younger than 50, and 30% of life years lost to BC are among women diagnosed in their 40s [ 4 ].…”

Triple-Negative Breast Cancer: A Review of Current Curative Intent Therapies

“…In Canada, 28 900 new cases of breast cancer are projected in 2022, representing over 25% of all new cancer diagnoses in women [ 1 ]. Triple-negative breast cancer (TNBC) accounts for approximately 10–20% of all cases [ 2 ].…”
