About 2 in 5 Canadians will develop cancer in their 838,724 lifetime and about 1 in 4 Canadians will die of cancer. Canadians were alive at In 2013, it is estimated that 187,600 Canadians will the beginning of 2009 2 in 5 develop cancer and 75,500 will die of cancer. More with a cancer diagnosed Canadians will than half of new cancer cases (52%) will be lung, in the previous develop cancer in breast, colorectal and prostate cancer. Lung cancer is 10 years their lifetime the leading cause of cancer death, causing more cancer deaths among Canadians than the other three cancer types combined. Despite this large impact, there has been a significant drop in the lung cancer death rate (especially for men) over the past 20 years, which has driven a decline in the overall cancer death rate. 187,600 Slightly more men than women get cancer in Canada, Canadians will be diagnosed and the vast majority (88%) of Canadians who develop % with cancer in 2013 cancer are over the age of 50. However, cancer can 63 occur at any age. Its impact at a younger age can be 75,500 The likelihood of Canadians particularly devastating: according to Statistics Canadians with cancer will die of cancer Canada, in 2009, cancer was the leading cause of surviving 5 years relative in 2013 disease-related death in children under the age of to the general 15 years. population Overall, the five-year relative survival ratio for people diagnosed with cancer is 63%, but it ranges widely by the type of cancer. Some cancers have very high 1 in 4 five-year relative survival ratios, including thyroid Canadians will die cancer (98%). Other cancers have consistently low of cancer five-year relative survival ratios, such as pancreatic cancer (8%).

This means that about type and allocation of health resources needed. The 2.5% of the Canadian population were living with, or data are also essential in focusing prevention efforts, in beyond, a cancer diagnosis in the decade leading up both primary prevention of cancer and secondary to 2009. prevention, allowing more effective treatment of This year’s publication also features an in-depth certain cancers through earlier detection. Finally, these analysis of liver cancer (Chapter 7: Special topic: Liver statistics can be useful for prioritizing services to help cancer). This cancer is one of the fastest growing cancer Canadians and their families who have been affected types in Canada with regard to new cases and deaths. by cancer and who may need supportive care after It is increasing particularly quickly in men, with an their treatment has ended. We hope that our readers average annual percent increase in incidence of 3.6% will think critically about what these numbers mean (1970 to 2007). An estimated 1,550 men and 490 and how they can be used to improve survival, develop women will be diagnosed with liver cancer this year. better overall care for those with cancer and reduce Major risk factors for liver cancer include viral cancer incidence in Canada. hepatitis infection (hepatitis B and C), smoking, alcohol consumption and obesity. A higher risk of liver cancer in lower income populations and concomitant barriers to accessing healthcare, early detection and treatment need to be investigated further to reduce the impact of this cancer. More Canadian data are also needed to understand the best strategies for risk reduction, early detection and treatment of hepatitis infection, as well as approaches to community engagement in promoting healthy behaviours in hard-to-reach populations.
