Data for 4 most common cancers are from BC, AB, SK, MB, NB, NS and NL.
Data for all cancers are from BC, AB, SK, MB, ON, NB, NS and NL.
The Canadian Cancer Society’s (CCS) projected 2014 cancer incident cases were used for this indicator. CCS projections are derived from statistical models incorporating data obtained from the Canadian Cancer Registry, National Cancer Incidence Reporting System, Canadian Vital Statistics’ Death Database, and population life tables, censuses and forecasts.
The indicator is a ratio, not a rate. As such, the numerator is not a complete subset of the denominator. Cases included in the numerator could have been diagnosed in previous years or could be recurrent cases.
