According to Healthline, colorectal cancer is rising fastest among Hispanic and Latino adults younger than 50, a trend underscored by the diagnosis of Azucena Reyes at age 32. Reyes, who was initially told by doctors that she was too young to develop the disease, discovered a tumor after seeking hospital care for severe stomach pain and nausea in August 2015. Medical experts emphasize that warning signs require diagnostic evaluations regardless of age, despite standard screening recommendations starting at 45.
Early Symptoms and Diagnostic Challenges for Young Adults
Reyes spent three months navigating tumor removal and medical reassurances that she could not have cancer due to her age and demographic. According to her interview with Healthline, medical personnel informed her that she had little to no chance of developing the disease at 32. Two months later, the tumor returned, resulting in a stage 3B colon cancer diagnosis.
Richard Wender, MD, Medical Advisor at the Colorectal Cancer Alliance, told Healthline that testing for individuals under 45 typically occurs in response to active symptoms. Wender advises anyone experiencing warning signs to seek medical evaluation immediately, noting that colorectal cancer can develop at any age.
Pro Tip: Wender recommends that individuals under 45 without insurance coverage for a screening colonoscopy ask their doctors about non-colonoscopy tests, such as FIT-DNA (Cologuard), FIT-RNA (Colosense), or Fecal immunochemical testing (FIT), to reserve colonoscopy for positive initial results.
Warning Signs That Require Medical Evaluation
According to Wender, patients of any age should reach out to a physician if they experience specific red-flag symptoms. These clinical indicators include blood in the stool or rectal bleeding, persistent changes in bowel habits like new diarrhea or constipation, and unexplained abdominal pain, cramping, or bloating.
Additional warning signs outlined by medical experts include unexplained anemia, unintentional weight loss, and persistent fatigue. Furthermore, Wender notes that asymptomatic individuals under 45 should still undergo screening if they are genetic carriers of familial mutations like Lynch syndrome or Familial Adenomatous Polyposis, possess a strong family history of cancer or polyps, or have inflammatory bowel diseases such as Crohn’s disease or Ulcerative Colitis.
Treatment Side Effects and Long-Term Management
Reyes underwent 12 rounds of chemotherapy, which significantly altered her body. She reported gaining weight from roughly 120 pounds up to nearly 250 pounds during treatment, alongside numbness in her feet that impaired her ability to walk. Extensive physical therapy and weight loss helped her recover mobility, though digestive complications persisted.
According to Reyes, she deals with permanent dietary restrictions, low thyroid function, low B12 levels requiring regular shots, and low iron managed through infusions. Despite these ongoing challenges, she maintains a high-fiber, low-red-meat diet and undergoes routine bloodwork and screenings.

Potential Factors Driving Early-Onset Rates
While medical researchers have not identified a single root cause for rising rates among younger populations, Wender told Healthline that experts point to multiple overlapping factors. These potential contributors include changes in dietary patterns featuring high intake of ultra-processed foods and red meat, rising rates of overweight and obesity, and environmental exposures such as microplastics and pollutants.
Additional factors under investigation include alterations in the gut microbiome, such as colibactin-producing E. coli, antibiotic use, and the physiological impacts of stress on genetic expression. Wender suggests that screening age thresholds may need to be lowered further below 45 in the future if these upward trends continue.
Advocacy and Community Outreach for Spanish Speakers
Finding support proved difficult for Reyes during her recovery due to a lack of age-appropriate peer networks and advocacy groups. About a year and a half after completing chemotherapy, she connected with the colorectal community through an online page called Living Active After Cancer.
Today, Reyes serves as a member of the Colorectal Cancer Alliance’s Never Too Young Taskforce. She focuses heavily on outreach within Spanish-speaking communities, where she notes a distinct gap in equal access to colon cancer information and Spanish-speaking advocates. She directs individuals to educational resources like colorectalcancer.org to help them understand their risks and evaluate screening options.
Frequently Asked Questions
What age does routine colorectal cancer screening start?
Preventive Services Task Force recommend beginning routine screenings at age 45 for individuals at average risk.
Can younger adults get colorectal cancer?
Yes. According to health experts, colorectal cancer rates are rising among adults younger than 50, particularly among Hispanic and Latino populations, making symptom evaluation critical regardless of age.
What non-colonoscopy screening options exist for younger adults?
Doctors can evaluate patients using stool-based tests such as FIT-DNA (Cologuard), FIT-RNA (Colosense), or Fecal immunochemical testing (FIT), particularly when insurance does not cover a screening colonoscopy for asymptomatic individuals under 45.
