This article provides an overview of cancer in Canada in 1984, including an analysis of geographic patterns by province. Trends for selected sites of cancer incidence from 1970 to 1984 and cancer mortality from 1970 to 1987 are also examined. Finally, trends since 1970 in cancer incidence and mortality are examined in the context of strategies for cancer control. Because of the need to assemble cancer information from a variety of sources within each province and territory, several years elapse between cancer diagnosis and the compilation of national figures. Still, the year-to-year analysis of incidence data in this article provides valuable information of cancer trends. In recent years, considerable improvements in Canada's system of cancer registration have led to improved consistency among provinces for both age-standardized rates and mortality/incidence ratios.
本文概述了1984年加拿大的癌症情况，包括按省份对地理模式的分析。还研究了1970年至1984年选定癌症发病部位的趋势以及1970年至1987年的癌症死亡率。最后，在癌症控制策略的背景下审视了自1970年以来癌症发病率和死亡率的趋势。由于需要在每个省和地区内从各种来源收集癌症信息，从癌症诊断到全国数据汇编会间隔数年。尽管如此，本文对发病率数据的逐年分析仍提供了有关癌症趋势的宝贵信息。近年来，加拿大癌症登记系统有了显著改进，使得各省在年龄标准化率和死亡率/发病率比率方面的一致性得到了提高。
