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
Prostate cancer is the leading cause of new cancer cases among males in both Simcoe Muskoka and Ontario. 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 2018 among Simcoe Muskoka male residents, there were nearly 500 new cases of prostate cancer diagnosed for an age-standardized incidence rate of 142 (129.3, 154.9) new cases per 100,000. This was significantly higher than the Ontario male prostate cancer incidence rate of 118 (115.5, 120.5) new cases per 100,000. Prostate cancer incidence rates dropped significantly from 2011 to 2014 in both Simcoe Muskoka and Ontario as a whole. The rates have been increasing since 2014, with the 2018 rates significantly higher than 2014 for both Simcoe Muskoka and Ontario.
As of 2014, the Canadian Task Force on Preventative Health Care recommends against PSA-based screening for prostate cancer for men of all ages. From 2012 to 2018, the US Preventative Services Task Force also recommended against PSA-based screening for prostate cancer for men of all ages. These updated recommendations likely contributed to the significant decrease in prostate cancer incidence observed both in Simcoe Muskoka and Ontario starting in 2012.
By Age Group
The risk of being diagnosed with prostate cancer for a male increases significantly with age. The age-specific prostate cancer incidence rates between 2010 and 2018 (combined) in Simcoe Muskoka were highest among seniors 65 years of age and older. The age-specific male prostate cancer incidence rates in Simcoe Muskoka were significantly higher than the comparable provincial rates for seniors 65 years of age and older.
