A recent study published in the Canadian Medical Association Journal has raised serious concerns about the future of cancer in Canada, predicting over 250,000 new cases and nearly 88,000 cancer-related deaths by 2026. The research highlights that lung, breast, prostate, and colorectal cancers will constitute nearly half of all new diagnoses. Compounding these grim statistics, a separate study reveals that survivors of cancer during adolescence and young adulthood are at a heightened risk of developing new cancers later in life.
Rising Cancer Incidence Amidst an Ageing Population
The study indicates that 42 per cent of Canadians will be diagnosed with cancer at some point in their lives. The significant growth of Canada’s population—an increase of approximately 9.5 per cent from 2020 to 2025, largely due to immigration—coupled with an ageing demographic, is a primary factor in the escalating cancer incidence. By 2025, a record 19.5 per cent of citizens will be aged 65 and over.
As the population ages, the implications for public health are profound. The study notes, “An ageing and growing population has resulted in a greater number of people diagnosed with or dying from cancer year after year, with a major economic impact on society.”
Common Cancer Types and Mortality Rates
The research outlines the most frequently diagnosed cancers for men and women. For males, prostate cancer is projected to account for 23 per cent of diagnoses, followed by lung (12 per cent), colorectal (11 per cent), and bladder cancers (8 per cent). In contrast, breast cancer will dominate among females at 26 per cent, with lung (14 per cent), colorectal (9 per cent), and uterine (7 per cent) cancers also prevalent.
When examining cancer mortality, lung cancer is expected to be the leading cause of cancer-related deaths, responsible for one in five such fatalities, with alarming projections of 21 per cent for men and 23 per cent for women. The study anticipates that the five leading causes of cancer death—lung, colorectal, pancreatic, breast, and prostate cancers—will collectively account for over half of all cancer deaths in Canada by 2026.
Long-term Risks for Young Cancer Survivors
In a separate but equally concerning study, researchers have discovered that individuals who survived cancer as teens or young adults face a doubled risk of developing new cancers compared to the general population. Miranda Fidler-Benaoudia, a cancer epidemiologist at the University of Calgary and Cancer Care Alberta, emphasises that the focus of this research was on the emergence of new cancers, rather than recurrences of existing ones.
The increased likelihood of subsequent cancers is largely attributed to the treatments used for initial diagnoses. Fidler-Benaoudia explains, “There really is a delicate balance between cure and long-term quality of life. Radiation is a recognised cause of cancer. While it is necessary for treating original cancers, it simultaneously increases the risk of developing another cancer due to the irradiated area.”
While treatment methods have improved, the potential for long-term adverse effects remains a critical concern. Genetics also play a significant role in the likelihood of developing subsequent cancers, underscoring the complexity of cancer survivorship.
Addressing the Silent Health Crisis
Calls for action are growing louder regarding the rising rates of cervical cancer, labelled as the “fastest-rising form of cancer” in Canada. The Society of Gynecologic Oncology of Canada has urged the federal government to take more decisive measures to combat this burgeoning health crisis. Dr. Shannon Salvador, the Society’s president, stated, “Canada is currently facing a silent national health crisis,” and emphasised the need for urgent attention.
In response to these alarming trends, the federal government has proposed an action plan aimed at eradicating cervical cancer as a public health issue by 2040. Additionally, advocacy groups like Colorectal Cancer Canada are pushing for an earlier screening age for colorectal cancer, suggesting a routine screening age of 45 for average-risk Canadians. Prince Edward Island has already taken the lead in this initiative, becoming the first province to adopt this recommendation.
Why it Matters
The projections outlined in these studies serve as a wake-up call for Canadian healthcare policymakers and the public alike. With a substantial portion of the population likely facing cancer diagnoses in their lifetime, the need for improved screening, treatment options, and public health initiatives has never been more pressing. As Canada grapples with these challenges, a concerted effort to enhance cancer care and prevention strategies will be essential in mitigating the impact of this devastating disease on individuals and society as a whole.
