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 cancer over a given period of time. In 2018 among Simcoe Muskoka residents, there were over 550 new cases of lung cancer diagnosed for an age-standardized incidence rate of 76 (69.5, 82.4) new cases per 100,000 population. This was significantly higher than the Ontario lung cancer incidence rate of 64 (62.8, 65.3) new cases per 100,000.
The lung cancer incidence rates in Simcoe Muskoka have not changed significantly over the nine-year period from 2010 to 2018.. The overall provincial lung cancer incidence rate decreased at small but significant rate over this same period. The Simcoe Muskoka rates were consistently above the Ontario rates over this nine-year period.
By Sex
In 2018, the age-standardized incidence rate for lung cancer among Simcoe Muskoka males was 76 (66.8, 85.9) new cases per 100,000, which was not significantly different from the female rate of 71 (62.8, 80.8) new cases per 100,000. The 2018 age-standardized lung cancer incidence rate for Ontario males was not significantly different from the comparable local rate; however, the Ontario lung cancer incidence rate for females was significantly lower than the rate for Simcoe Muskoka females. There was a small but significant downward trend in the Simcoe Muskoka lung cancer incidence rate from 2010 to 2018 among males with rates decreasing by approximately two per cent per year on average; however, there was no discernable trends in the rates for females for the nine-year period from 2010 to 2018
By Age Group
The risk of being diagnosed with lung cancer increases significantly with age. The age-specific lung cancer incidence rates between 2010 and 2018 (combined) in Simcoe Muskoka were highest among those 75 years and older at 445 (423.6, 467.0) new cases per 100,000 population. The age-specific lung cancer incidence rates in Simcoe Muskoka were significantly higher than the comparable provincial rates all age groups among adults 45 years of age and older.
