This study examines trends in mesothelioma incidence and survival in Canada, focusing on data from British Columbia (B.C.) and Ontario. Despite the asbestos ban in Canada, mesothelioma remains a significant concern due to its long latency period. Using data from cancer registries in B.C. (1992-2016) and Ontario (1993-2017), the study analyzes trends in mesothelioma incidence, survival rates, and geographical patterns. The incidence of mesothelioma has steadily increased, with a notable rise in women and older populations. Survival rates remain low, with median survival times of 8 months in both provinces, and 5-year survival rates of only 3.5% in B.C. and 7.6% in Ontario. Geographic variability was observed, with higher rates in areas with historical asbestos use. The study highlights the need for ongoing surveillance, better exposure history data, and the establishment of a mesothelioma registry to improve understanding and prevention of this fatal disease.
