Lung Cancer 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).

Overall

In 2016, 339 Simcoe Muskoka residents died of lung cancer for an age-standardized mortality rate of 50 (44.5, 55.3) deaths per 100,000 population. This was significantly higher than the Ontario lung cancer mortality rate of 44 (43.2, 45.3) deaths per 100,000. Lung cancer is the leading cause of cancer deaths in both Simcoe Muskoka and Ontario.

The chart below shows the trend in the lung cancer mortality rates in Simcoe Muskoka and Ontario over the 31 year period from 1986 to 2016. Lung cancer mortality rates, both in Simcoe Muskoka and Ontario, decreased significantly over this time period. The Simcoe Muskoka rates were above the Ontario rates over this entire 31 year period of time.

By Sex

In 2016, the age-standardized mortality rate for lung cancer among Simcoe Muskoka males was 56 (47.7, 64.8) deaths per 100,000, which was not significantly different from the female rate of 45 (38.3, 52.5) deaths per 100,000. The 2016 age-standardized lung cancer mortality rates for both Ontario males and females were not significantly different from the comparable Simcoe Muskoka rates.

The chart below shows the trend in lung cancer mortality rates for males and females in Simcoe Muskoka from 1986 to 2016. The lung cancer mortality rates for males and females in Simcoe Muskoka demonstrated opposite trends over this time period, with male rates declining significantly and female rates increasing significantly. The male lung cancer mortality rates were more than triple the females rates in the late 1980’s and early 1990’s and remained significantly higher than the female rates until the mid-2000’s; however, since 2008 the lung cancer mortality rates for males and females in Simcoe Muskoka have not differed significantly. This pattern can be explained by different long-term smoking trends for men and women over the past century, with smoking rates peaking in women in the late 1970’s, nearly 20 years after smoking rates peaked in men.

The age-specific lung cancer mortality rates for Simcoe Muskoka males and females have demonstrated different patterns over the past quarter of a century. The male lung cancer mortality rates have declined significantly across all age groups for adults 45 years of age and older when comparing the period of time from 1986-1993 with the period from 2010-2016. Among Simcoe Muskoka females, lung cancer rates have remained the same for adults 45 to 74 years of age across these same time intervals; however, rates have increase significantly among females 75 years of age and older.
