Early-Onset Colorectal Cancer & Gut Health | Houston, Texas
Saturday, December 27, 2025 | By: Houston Concierge
Colorectal cancer has traditionally been considered a disease of older adults, but rates among people under 55 have been rising. In fact, studies show that early-onset colorectal cancer has doubled since 1995. While researchers are still investigating all the causes, emerging science is uncovering clues that may help with awareness, early detection, and gut health strategies.
Dr. Gregory Burzynski at Houston Concierge Medicine in Houston, Texas, emphasizes that understanding risk factors and being proactive about health is increasingly important. By learning about factors that may contribute to early-onset colorectal cancer and taking steps to support gut health, individuals can make informed choices that are associated with better long-term wellness.
What the Research Reveals
Recent studies from UC San Diego have identified a potential contributor: certain strains of E. coli bacteria that produce a genotoxin called colibactin. Laboratory studies show this toxin can damage DNA in gut cells, which may contribute to DNA changes associated with cancer risk.
Not everyone exposed to these bacteria will develop colorectal cancer, but these findings highlight the role the gut microbiome—the community of bacteria and microorganisms in the digestive tract—may play in overall health.
Why Early-Onset Colorectal Cancer Is Rising
Several factors may be contributing to the increase in colorectal cancer among younger adults:
- Microbiome Imbalances: Colibactin-producing E. coli strains may cause DNA changes early in life, long before any symptoms appear.
- Lifestyle and Diet: Diets high in processed foods, low in fiber, sedentary behavior, and obesity are associated with changes in gut health that may increase risk.
- Environmental Influences: Research suggests that people living in urban or industrialized areas have higher rates of early-onset colorectal cancer compared with those in rural or less industrialized regions. This points to the influence of environmental exposures and lifestyle patterns.
Dr. Greg Burzynski and his team understand the importance of a proactive, prevention-focused approach to healthcare. Waiting for symptoms to appear may not be sufficient, and understanding risk factors, lifestyle choices, and early screening options can help individuals make informed decisions about their long-term health.
Supporting Gut Health
A balanced gut microbiome is important for immune function, nutrient absorption, and overall wellness. Maintaining a healthy microbiome may be associated with reduced risk of various health issues over time. Strategies that may support gut health include:
- Diet Rich in Fiber: Fruits, vegetables, legumes, and whole grains help beneficial bacteria thrive.
- Fermented Foods: Yogurt, kefir, kimchi, and sauerkraut provide probiotics that may support microbial balance.
- Regular Physical Activity: Exercise supports gut motility and overall microbiome health.
- Limiting Processed Foods and Added Sugars: Diets high in processed foods can encourage growth of harmful bacteria.
- Screening and Regular Checkups: Screening is recommended according to current guidelines; discuss options with your physician to determine what is appropriate for you.
The Houston Concierge Medicine team helps patients incorporate these strategies in ways tailored to their lifestyle, genetics, and personal goals, offering personalized guidance that goes beyond symptom management.
The Role of Early Detection
Early detection remains an important factor in managing colorectal cancer risk. Early-onset colorectal cancer can sometimes go unnoticed because routine screenings typically begin at age 45, and symptoms may be subtle—like changes in bowel habits, fatigue, or mild abdominal discomfort.
Proactive discussions with a healthcare provider, along with personalized screening plans, can be associated with earlier identification of potential issues and help patients make informed decisions about their health. Patients who understand their risk and explore prevention and early detection options may have better long-term outcomes.
Lifestyle and Environment
Research also indicates that lifestyle and environmental factors play a role in colorectal cancer risk. Populations in rural or less industrialized areas often have lower rates of early-onset colorectal cancer, suggesting that diet, exposure to pollutants, and lifestyle differences may influence risk.
By focusing on balanced nutrition, regular physical activity, stress management, and preventive care, patients can adopt strategies associated with overall gut and digestive health. Houston Concierge Medicine combines scientific insights with personalized guidance to help individuals take a proactive approach.
