cancer statistics

Cancer statistics at a glance

Cancer statistics tell us how many people in Canada are diagnosed with and die from cancer each year. They show us the trends in new cancer cases and cancer deaths. 
Cancer statistics also tell us the likelihood of surviving a cancer diagnosis and the percentage of people who are alive years after a cancer diagnosis.

Canadian provinces and territories collect data on cancer cases and cancer deaths. These data are combined to provide a picture of how cancer affects all of Canada.

Statistics are an important part of healthcare planning and of measuring the success of cancer control.

 

Incidence and mortality

Incidence is the number of new cases of cancer. Mortality is the number of deaths due to cancer. Researchers use the most up-to-date data available and statistical methods to estimate the number of new cancer cases and deaths for the current year.
Researchers estimated that there would be 225,800 new cancer cases and 83,300 cancer deaths in Canada in 2020. (The number of estimated new cases does not include non-melanoma skin cancer cases.)

Cancer is the leading cause of death in Canada and is responsible for 30% of all deaths.

 

It was estimated that in 2020:

  • 115,800 Canadian men would be diagnosed with cancer and 44,100 men would die from cancer.
  • 110,000 Canadian women would be diagnosed with cancer and 39,300 women would die from cancer.
  • On average, 617 Canadians would be diagnosed with cancer every day.
  • On average, 228 Canadians would die from cancer every day.
  • Lung, breast, colorectal and prostate cancer are the most commonly diagnosed types of cancer in Canada (excluding non-melanoma skin cancer). 
 
  • These 4 cancers account for about half (48%) of all new cancer cases.
  • Prostate cancer accounts for one-fifth (20%) of all new cancer cases in men.
  • Lung cancer accounts for 14% of all new cases of cancer.
  • Breast cancer accounts for one-quarter (25%) of all new cancer cases in women
  • Colorectal cancer accounts for 12% of all new cancer cases.
     

Chances (probability) of developing or dying from cancer

  • Nearly 1 in 2 Canadians (45% of men and 43% of women) is expected to develop cancer during their lifetime.
  • About 1 out of 4 Canadians (26% of men and 23% of women) is expected to die from cancer.
 

Trends in cancer rates

Cancer is a disease that mostly affects Canadians aged 50 and older, but it can occur at any age. Across Canada, cancer incidence rates vary because of differences in risks (including behaviours and exposures) and early detection practices. Similarly, rates of cancer death vary because of differences in incidence. Mortality rates may also vary due to differences in access to and outcomes of cancer control activities (for example, screening, diagnosis, treatment and follow-up) across the country.

Survival

There are many different ways of measuring and reporting cancer survival statistics. Net survival is an estimate of the percentage of people who are alive at some point in time after their cancer diagnosis, accounting for other causes of death. Most survival statistics are reported for a specific time period, usually 5 years.

Based on data from 2012 to 2014, 63% of Canadians diagnosed with cancer are expected to survive for 5 years or more after a cancer diagnosis. This is up from 55% in the early 1990s. In the 1940s, survival was about 25%.

Survival rates vary from low to high depending on the type of cancer. Based on 2012–2014 data:
• The 5-year net survival rate for lung cancer is low (19%).
• The 5-year net survival rate for colorectal cancer is about average (65%).
• The 5-year net survival rate is high for prostate cancer (93%) and breast cancer (88%).
