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. Cancer sites were coded using the Third Edition of the International Classification of Diseases for Oncology (ICDO-3). 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 incidence data presented on this and other HealthSTATS pages reflect the new rules for counting multiple primary cancers. To ensure consistent interpretation of trends, cancer incidence data will only be presented from 2010 onward on all HealthSTATS pages.
Overall
The rate of new cancer cases (also called the incidence rate) provides a measure of the risk of developing any type of cancer over a given period of time. In 2018 among Simcoe Muskoka residents, there were over 3,900 new cases of cancer diagnosed for an age-standardized incidence rate of 567 (549.4, 585.5) new cases per 100,000 population. This was significantly higher from than the Ontario cancer incidence rate of 543 (539.5, 546.8) new cases per 100,000.
The cancer incidence rates both in Simcoe Muskoka and Ontario decreased at a small but significant rate between 2010 and 2018, with an annual percentage decrease of approximately one per cent per year. The Simcoe Muskoka rates were significantly above the Ontario rates for eight of the nine years.
By Sex
In 2018, the age-standardized incidence rate for all cancers among Simcoe Muskoka males was 611 (584.9, 638.9) new cases per 100,000, which was significantly higher than the female rate of 535 (510.3, 559.7) new cases per 100,000. The 2018 age-standardized cancer incidence rates for Ontario males and females were significantly lower than the comparable Simcoe Muskoka rates.
The cancer incidence rates among Simcoe Muskoka males decreased significantly from 2010 to 2014, with an average annual per cent decline of approximately five per cent per year; however, from 2014 to 2018 the cancer incidence rate among Simcoe Muskoka males has remained stable. The cancer incidence rates among Simcoe Muskoka females did not change significantly over this nine-year period.
By Age Group
The risk of being diagnosed with cancer increases significantly with age. The age-specific cancer incidence rates between 2010 and 2018 (combined) in Simcoe Muskoka were highest among those 75 years and older at 2,682 (2,629.0, 2,735.1) new cases per 100,000 population. In contrast, the cancer incidence rate for children and youth under 20 years of age was only 19 (16.4, 21.7) new cases per 100,000 population. The age-specific cancer incidence rates in Simcoe Muskoka were significantly higher than the provincial rates for all age-groups among adults 45 years of age and older over this nine-year period.
