Scientists Uncover Why 11 Types of Cancer Are Rising in Young People
It is the kind of news that stops you in your tracks, even in the middle of a frantic commute through the Loop or a weekend stroll along the Lakefront Trail. For decades, the narrative around cancer was simple: it was a disease of aging, something that happened in the twilight years of a life. But the data is shifting, and for those of us living in a healthcare hub like Chicago, the reality is becoming impossible to ignore. We are seeing a disturbing trend where people in the prime of their lives—those in their 20s, 30s, and 40s—are facing diagnoses that were once rare for their age group.
This isn’t just a local anomaly or a series of unfortunate coincidences. It is part of a global surge in early-onset cancers that has caught the medical community’s attention. When you look at the scale of it, the numbers are jarring. According to research presented at the Union for International Cancer Control (UICC) congress in Geneva in September 2024, colorectal cancer rates among 25 to 49-year-olds have climbed across 24 different countries. This list includes the United States, along with the UK, France, Australia, Canada, Norway, and Argentina. For many Chicagoans, this means that the “standard” screening ages we’ve been told for years may no longer be the only benchmarks we need to worry about.
The Scale of the Early-Onset Surge
The investigation, conducted by researchers from the American Cancer Society (ACS) and the World Health Organization’s (WHO) International Agency for Research on Cancer, analyzed data from 50 countries. The findings revealed a peculiar and concerning pattern: in 14 of those nations, the increase in cancer incidence was seen exclusively in younger adults, while rates among older populations remained stable. This suggests that something in the modern environment or lifestyle is specifically triggering these malignancies in younger generations.
Breast cancer provides one of the most striking examples of this shift. A report from the ACS indicates that while overall deaths from breast cancer in women have dropped by approximately 10% over the last decade, the incidence rates are actually rising. They are increasing by 1% per year, but for women under the age of 50, that rate jumps to 1.4% per year. This trend isn’t a sudden spike; epidemiological evidence suggests it began as far back as the 1990s.

The broader picture is even more sobering. One study found that between 1990 and 2019, the global incidence of early-onset cancer increased by 79%, and cancer-related deaths in younger people rose by 29%. In the U.S. Specifically, a report published in The Lancet Public Health highlighted that incidence rates have steadily risen across 17 different types of cancer, with Generation Xers and Millennials being particularly affected. When you consider the density of our city, from the high-stress corporate environments of the Magnificent Mile to the diverse neighborhoods of the Northwest Side, these statistics hit home. We are talking about people in their peak earning years, parents of young children, and individuals who previously considered themselves “healthy.”
Navigating the New Reality of Preventative Care
The challenge for patients in Chicago is that early-onset symptoms are often dismissed. Because these patients don’t fit the traditional “cancer profile,” their concerns are sometimes brushed off as stress, IBS, or general fatigue. This is why organizations like the UICC are urging physicians to heighten their vigilance. The goal is to ensure that symptoms in younger patients are not overlooked, leading to earlier detection and better outcomes.
For those of us navigating this, it requires a shift in how we approach preventative health screenings. People can no longer rely solely on the “age 45” or “age 50” milestones if we have family histories or persistent symptoms. The integration of advanced diagnostics at institutions like Northwestern Medicine, the University of Chicago Medicine, and Rush University Medical Center has made Chicago a leader in oncology, but the first step always begins with a patient advocating for themselves in a primary care setting.
Local Resource Guide: Building Your Support Team
Given my background in analyzing health trends and community resources, I know that a global statistic is cold comfort when you’re actually looking for help. If you or a loved one in the Chicago area are concerned about these rising trends, you need a specific type of professional support. You aren’t just looking for a general practitioner; you need specialists who are attuned to the nuances of early-onset malignancy.
Here are the three categories of local professionals you should prioritize when building your preventative or diagnostic team:
- Early-Onset Screening Specialists (Gastroenterologists & Oncologists)
- Look for providers who specifically mention “early-onset” colorectal or breast cancer in their practice focus. You want a clinician who doesn’t just follow the standard age-based guidelines but is comfortable ordering screenings for patients in their 30s based on symptomatic presentation or nuanced risk factors. Ensure they are board-certified and affiliated with a major research hospital to ensure they have access to the latest diagnostic tools.
- Clinical Genetic Counselors
- With the rise of cancers in Gen X and Millennials, understanding hereditary risk is critical. Seek out counselors who specialize in hereditary cancer syndromes (such as Lynch syndrome for colorectal cancer). A qualified counselor should be able to provide a comprehensive pedigree analysis and help you navigate the complex decisions regarding genetic testing and how those results impact your family members.
- Integrative Metabolic Health Consultants
- While not a replacement for oncology, these professionals help manage the lifestyle factors that may contribute to systemic inflammation. Look for licensed practitioners (such as Registered Dietitians or certified health coaches) who work in tandem with medical oncologists. The criteria here should be a “collaborative care” model—they should be willing to communicate directly with your doctor to align your nutrition and lifestyle plan with your clinical treatment.
The most important thing to remember is that while the data is concerning, early detection remains the most powerful tool we have. Being proactive about your health isn’t about living in fear; it’s about taking control of the variables you can influence.
