Overall the number of cancers in Canada is declining, but the number of cancer cases and deaths is increasing slightly due to population growth and aging, according to a new study on cancer data published in CMAJ (Journal of the Canadian Medical Association).

The study is the result of a partnership between the Cancer Society of Canada, Statistics Canada and the Canadian Public Health Agency. It is estimated that there will be 233,900 new ones cancer 85,100 cancer cases and deaths in Canada in 2022 and provide provincial, regional and national estimates. This is up from an estimated 229,200 cancer cases and 84,600 cancer deaths in 2021.

In Canada, cancer is the leading cause of death, and 43% of all people in the country are expected to receive it cancer diagnosis in their lives, according to previous estimates.

“Cancer treatment has an impact on cancer in Canada,” said Dr. Darren Brenner, an oncologist at the School of Cumming Medicine, University of Calgary and co-author of the study. “The number of years corresponding to new times and deaths continue to decrease, in large part because of the efforts being made in the country. cancer prevention, screening, location and treatment. There has also been an increase in overall life expectancy among Canadians, which is good news. “

  • Lung cancer is projected to be the most common cancer in 2022, with an estimated 30,000 new cases, followed by breast cancer (28,900), prostate cancer (24,600) and cancer (24,300).
  • These 4 types of cancer will account for almost half (46%) of all cancers expected to be diagnosed in Canada by 2022.
  • In men, prostate cancer it is predicted to be the most common type of cancer, about 1 in 5 of them cancer, followed by lung cancer.
  • Breast cancer is expected to be the most common cancer in women, about 1 in 4 of them cancer, then lung (13%), colorectal cancer (10%) and cervical cancer (7% ) of cancer.
  • The maternal mortality rate in men is estimated at 34% higher than in women.

Although mortality and survival for many types of cancer have improved significantly over the past 3 years, for some, more research and investment is needed in new therapies. For example, lack of progress in early detection and treatment for pancreatic cancer explains why it is the third leading cause of cancer death in Canada despite being the 11th most common cancer.

“The 2022 forecast reminds us that we need to do more to change the future of cancer in Canada,” said Elizabeth Holmes, General Manager of Health Policy at the Canadian Cancer Society and co-author of the study. “To reduce the number of people living with cancer and to ensure that more people survive the disease, we must continue to invest in and support new research and improved public health policies with implementation across the autonomous system. “

Commentary published in this issue CMAJ discusses why and how the papillomavirus virus (HPV) test could replace the Papanicolaou (Pap) test to diagnose routine cervical cancer in Canada.

Over the past 50 years, the number of cervical cancers has decreased in Canada with the introduction of screening programs. By 2022, the number of cervical cancers is projected to be 7.5 per 100,000 and is expected to decrease in the future with the spread of HPV and HPV testing as the first test.

“The transition to the HPV PCR test for cervical cancer represents an unconventional example where the most cost-effective and cost-effective testing method has been found to change the pathogenesis that would lead to the success of the HPV immunization program,” writes Drs. . Emily Delpero and Amanda Selk, obstetrics and gynecologists at the Women’s College Hospital of Sinai Medical Center, Toronto. “However, international expertise demonstrates the importance of first and foremost public benefit and contributing education to ensure effective change and success.”
