When people talk about cancer risks, most jump to the usual culprits: smoking, too much alcohol, all those hours in the sun, maybe a bad diet or environmental toxins. And yes, those things do push your risk up. But there’s a bigger factor hiding in plain sight, one you can’t escape no matter how perfectly you live: getting older.It might sound obvious, of course risk goes up as you age, but the reality is pretty sobering. As older adults become a bigger part of society, cancer is turning into an ageing problem more than ever before. In the US, nearly all cancer incidence graphs climb sharply after age 60, with more than 1,000 cases per 100,000 people over that age. The National Cancer Institute says age is the single biggest risk factor for cancer, not just overall but for many individual types too.But there’s another side to this: Treating cancer in elderly patients genuinely isn’t the same as treating it in someone 45 years old and otherwise healthy. According to The Conversation, Kristen Haase (University of British Columbia) and Shabbir Alibhai (University of Toronto) point out that health systems need to rethink how they care for older adults with cancer, making room for specialized geriatric oncology, not just pushing everyone through the same routine.
Why does age matter so much?
It’s biology. Cancer develops from an accumulation of genetic mistakes and damage that build up over a lifetime. The longer you live, the more time your body has to collect these changes. The immune system shifts with age, and the body handles damaged cells less well, which opens the door wider for cancer.But age isn’t destiny. Lifestyle risks like smoking, high alcohol intake, obesity, and infections all carry weight, and many of these are things we can change. The main takeaway, though, is hard to ignore: As more of us reach old age, more of us will face cancer as a reality.Demographics are already heading in that direction. Look at Canada, for instance: by 2068, nearly a third of the population will be over 65. That creates a huge strain on healthcare systems built around traditional adult care, not those dealing with the more complex situations that often come with older patients.See, not every person over 80 is the same. Some may be managing other chronic illnesses, from diabetes and heart disease to arthritis or cognitive challenges. Just because two people have the same birth year doesn’t mean they have the same health or the same needs.This is where geriatric assessment comes in. Modern cancer care guidelines now recommend a detailed, individualized review for older patients before treatment begins. Doctors check not just physical health, but cognitive function, medications, nutrition, independence, and the social support a person has. It’s not about denying care because of age; it’s about finding the route that gives the best outcome for that unique person.Because there’s a world of difference between two 78-year-olds. One could be out dancing, hopping on a bus to new cities, or running errands solo, while the other may be struggling just to get through the day without help. A one-size-fits-all treatment plan just doesn’t make sense.Even though the evidence for specialized geriatric cancer care is solid, the reality on the ground falls short. In Canada, for example, geriatric oncology clinics are scarce. There are provinces without any specialized services for older adults with cancer. Based on input from patients, caregivers, and professionals, the message is clear: older adults need more support, both for their health and quality of life, but also for the wider healthcare system. There’s even a financial bonus—research suggests these clinics could save thousands of dollars per patient.But you can’t talk about this issue honestly without mentioning ageism. There’s a creeping bias in medicine, and in society, that sees declining health and dependence as inevitable with age. That mindset can lead doctors to pull back, maybe investigating less aggressively or skipping conversations about important aspects of care. But age shouldn’t automatically mean less effort or care. People age differently, and their goals vary too.
The bottom line?
Age raises cancer risk, but it shouldn’t become an excuse to offer older people less thoughtful, less personalized treatment. As populations continue to age, healthcare has to catch up—not by assuming all older people are alike, but by recognizing every individual’s story.Ultimately, the future of cancer care isn’t just about better drugs or high-tech treatments. It’s about really understanding, one patient at a time, what matters in their life, and how best to help them enjoy as much of it as possible.
