摘要

The article, "Cancer incidence, mortality and survival trends in Canada, 1970–2007," analyzed long-term trends for selected cancers (prostate, breast, lung and colorectal) in Canada using data from the Canadian Cancer Registry, National Cancer Incidence and Reporting System, and the Canadian Vital Statistics Death Database. The study first examined longterm trends for all cancers, followed by the 4 most common cancers in Canada, as they have the most notable changes in incidence or mortality trends in the past decade.
