By Age Group
Cancer deaths data are derived from the Ontario Cancer Registry (OCR) operated by Cancer Care Ontario. The OCR contains information on Ontario residents who have died of all types of malignant cancers. Cancer sites were coded using the Third Edition of the International Classification of Diseases for Oncology (ICDO-3).
In 2012 155 Simcoe Muskoka residents died of colorectal cancer with an age-standardized mortality rate for all ages and both sexes of 19 (16.2, 22.6) per 100,000 population. This was not significantly different from the Ontario colorectal cancer mortality rate of 16 (15.8, 17.0) per 100,000.
Figure one below shows the trend in colorectal cancer mortality in both Simcoe Muskoka and Ontario over the twenty-seven year period from 1986 to 2012. The colorectal cancer mortality rates both in Simcoe Muskoka and Ontario decreased steadily and significantly over this time period, with an average annual percentage decrease of nearly two per cent per year. The Simcoe Muskoka rates were above the Ontario rates for the majority of this twenty-seven year time-period.
In 2012, the age-standardized mortality rate for colorectal cancer among Simcoe Muskoka males was 23.5 (18.7, 29.3) per 100,000, which was significantly higher than the female rate of 16 (12.4, 20.8) per 100,000. The 2012 age-standardized colorectal cancer mortality rates for Ontario males and females were not significantly different from the comparable Simcoe Muskoka rates.
Figure two shows the trend in colorectal cancer mortality rates for males and females in Simcoe Muskoka over the twenty-seven year period between 1986 and 2012. The colorectal cancer mortality rates for males and females in Simcoe Muskoka have both decreased significantly over the past two decades, with the male rates being above the female rates for the entire time period.
By Age Group
Colorectal cancer mortality increases exponentially with age (see figure three). The age-specific colorectal cancer mortality rates between 2007 and 2012 (combined) in Simcoe Muskoka were highest among those 75 years and older at 226 (206.7, 247.5) deaths per 100,000 population. The age-specific colorectal cancer mortality rates in Simcoe Muskoka were significantly higher than the comparable provincial rates for older seniors 75 years of age and older.
