Cervical Cancer Incidence

Overall
By Age Group

Cancer incidence data are derived from the Ontario Cancer Registry (OCR) operated by Cancer Care Ontario. The OCR contains information on Ontario residents who have been newly diagnosed with all types of malignant cancers, with the exception of basal cell and squamous cell (non-melanoma) skin cancers. Beginning in 2014, the OCR adopted the National Cancer Institute (NCI) SEER standards for counting multiple primaries for cancer cases diagnosed in 2010 and beyond. This standard is more liberal than the previously used case counting rules from the modified version of the International Association of Cancer Registries (IACR). Cancer data presented on this and other HealthSTATS pages only includes cases captured using the more conservative IACR definition for all years in order to maintain comparability over time. As a result, figures presented on HealthSTATS may be lower than those reported by Cancer Care Ontario as they are using the revised counting methodology.

Overall

The rate of new cancer cases (also called the incidence rate) provides a measure of the risk of developing cancer over a given period of time. In 2012 among Simcoe Muskoka female residents, there were 24 new cases of cervical cancer diagnosed with an age-standardized incidence rate for females of all ages of 9 (5.6, 13.6) per 100,000 population. This was not significantly different from the Ontario female cervical cancer incidence rate of 8 (7.5, 8.8) per 100,000.

Figure one below shows the trend in cervical cancer incidence in both Simcoe Muskoka and Ontario over the twenty-seven year period from 1986 to 2012. The cervical cancer incidence rates in both Simcoe Muskoka and Ontario decreased steadily over this time period. In Simcoe Muskoka, cervical cancer incidence rates have decrease by an average of -2.9 (-3.9, -1.9) per cent per year, which was significantly faster than the overall provincial decrease of -1.6 (-1.8, -1.1) per cent per year.

By Age Group

Among Simcoe Muskoka females, the risk of being diagnosed with cervical cancer does not change significantly with age; however, for the province as a whole adult females between 20 and 44 years of age have significantly lower cervical cancer incidence than all older age groups. The age-specific cervical cancer incidence rates between 1986 and 2012 (combined) in Simcoe Muskoka were significantly higher than the comparable provincial rate for females between 20 and 64 years of age but were not significantly different from the province among seniors 65 years of age and older.
