THE MAGNITUDE OF THE LUNG CANCER PROBLEM IN CANADA
Canadian Medical Association Journal
|November 23, 1963
Summary
Lung cancer mortality in Canada significantly increased between 1931 and 1961, particularly in older males. Addressing smoking and environmental carcinogens is crucial to counter this rising trend.
Area of Science:
- Epidemiology
- Public Health
- Oncology
Background:
- Lung cancer poses a significant health challenge in Canada.
- Mortality rates serve as a key indicator of lung cancer's impact due to low survival rates.
Purpose of the Study:
- To define the extent of the lung cancer problem in Canada using available statistics.
- To analyze trends in lung cancer mortality rates from 1931 to 1961.
Main Methods:
- Statistical analysis of available mortality data.
- Examination of lung cancer death rates by sex and age group over a 30-year period.
Main Results:
- Male lung cancer death rates increased from 3.0 to 24.6 per 100,000 population; female rates rose from 1.6 to 4.0.
- The largest increases were observed in males aged 70-74 (18-fold) and females aged 80-84 (7-fold).
- In 1961, lung cancer caused 2774 deaths and was the leading cause of cancer death for males aged 40-79.
Conclusions:
- Lung cancer mortality in Canada has risen, though not as sharply as in some other nations.
- Reducing smoking rates and controlling environmental carcinogens are essential to mitigate the increasing trend of lung cancer.
