Incidence is expressed as the number of new cases of a given type of cancer diagnosed per year.
Mortality is expressed as the number of deaths attributed to a particular type of cancer during the year. The closer a value is to 1.0, the poorer the prognosis for that cancer. Readers requiring actual data or information on less common sites of cancer may refer to Tables 1 and 2 in Appendix I or to source publications. Some problems that may be inherent in using these statistics are considered below. The new CCR is regularly updated, it is internally linked to track patients with tumours diagnosed in more than one province, and its records are linked to death certificates.
