A recent report published by The Lancet medical journal suggests a significant increase in cancer cases and deaths globally by 2050, including in Canada. The study projects a rise from 18.5 million new cancer cases in 2023 to 30.5 million in 2050. Furthermore, cancer deaths are expected to surge from 10.4 million in 2023 to 18.6 million in 2050, marking a 75% increase in death rates.
The study highlights that the three leading causes of cancer deaths as of 2024—windpipe and lung cancers, colon and rectum cancers, and stomach cancer—are anticipated to escalate by 2050. In high-income countries like Canada, the rise is attributed primarily to aging populations.
Ali Mokdad, a professor at the University of Washington, notes that the aging population in Canada will lead to more cancer cases, despite a decline in cancer death rates per 100,000 over the years. The study emphasizes that Canada needs to bolster its healthcare systems to handle the impending surge in cancer cases, focusing on early screening and treatment.
Countries like Lebanon, however, are experiencing an increase in cancer rates and deaths due to factors such as smoking, environmental pollution, and alcohol consumption. Modifiable risk factors like tobacco use and poor diet contribute significantly to cancer deaths worldwide.
Dr. Keith Stewart from the Princess Margaret Cancer Care Network in Toronto stresses the strain on hospital resources due to the growing number of cancer patients. He emphasizes the need for better planning, increased resources, and improved care for cancer patients as the population ages and survival rates increase. Stewart suggests a comprehensive approach involving more beds, enhanced scheduling systems, and increased investment in at-home care to address the rising cancer burden effectively.
