Malignant Melanoma Mortality

Overall
By Sex
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).

This HealthSTATS page only includes deaths from malignant melanomas of the skin. Non-epithelial skin cancers, which are not included in these statistics, represent approximately 25% of skin cancer deaths that are tracked by the OCR. These statistics also do not include data for basal cell and squamous cell carcinomas, which are not tracked by the OCR. Exposure to ultraviolet (UV) rays is the most important risk factor for malignant melanomas. Sunlight is the main source of UV rays. Tanning beds and sun lamps are also sources of UV rays.

Overall

In Simcoe Muskoka from 2010 to 2016, 177 residents died from malignant melanomas of the skin for an age-standardized mortality rate of 4.3 (3.6, 4.9) deaths per 100,000 population. This was significantly higher than the Ontario malignant melanoma mortality rate of 3.4 (3.3, 3.5) deaths per 100,000.

The chart below shows the trend in malignant melanoma mortality in both Simcoe Muskoka and Ontario from 1986 to 2016, grouped into four distinct time periods. Neither the Ontario nor the Simcoe Muskoka rates have changed significantly since 1994. The Simcoe Muskoka rates have been significantly higher than the provincial rates since 1994.
