Colorectal cancer (CRC) incidence is rising, particularly among younger adults, a trend that’s prompting a reevaluation of prevention strategies. While screening remains crucial, experts emphasize a more holistic approach encompassing lifestyle factors, early detection of symptoms, and a deeper understanding of individual risk. A recent discussion with Jordan Karlitz, MD, highlighted three key pillars of CRC prevention that could help curb the increasing mortality rates associated with this disease.
The shift towards younger patients—some diagnosed in their 30s and 40s—is particularly concerning. According to the American Cancer Society, there has been a significant increase in early-onset colorectal cancer cases. The organization notes that while the overall incidence of colorectal cancer is decreasing due to screening, rates are increasing in adults younger than 50.
Dr. Karlitz, speaking at a recent medical conference, underscored the importance of moving beyond a solely screening-focused model. He advocates for a three-pronged strategy: optimizing screening practices, addressing modifiable risk factors, and improving symptom awareness. This approach, he argues, is essential to reversing the current trajectory.
Optimizing Screening: Beyond the Colonoscopy
For decades, colonoscopy has been the gold standard for CRC screening. However, Dr. Karlitz points out that it’s not the only effective option. Fecal Immunochemical Testing (FIT) and stool DNA tests, like Cologuard, offer non-invasive alternatives that can significantly increase screening rates. UCLA Health reports that these tests are becoming increasingly popular due to their convenience and accessibility.
The key, Dr. Karlitz emphasizes, is getting people screened *at all*. “We need to overcome barriers to colonoscopy, such as bowel preparation and cost, and offer a range of options to suit individual preferences and risk profiles,” he stated. Current guidelines generally recommend starting regular screening at age 45, but individuals with a family history of CRC or other risk factors may need to initiate earlier.
Addressing Modifiable Risk Factors: Lifestyle Matters
Lifestyle plays a significant role in CRC development. Established risk factors include a diet high in red and processed meats, obesity, physical inactivity, smoking, and excessive alcohol consumption. Dr. Karlitz stresses the importance of adopting a healthy lifestyle to mitigate these risks.
“We know that diet and exercise have a profound impact on gut health and inflammation, both of which are linked to CRC,” he explained. “Encouraging patients to adopt a diet rich in fruits, vegetables, and whole grains, coupled with regular physical activity, can significantly reduce their risk.” The American Institute for Cancer Research offers detailed dietary recommendations for cancer prevention on their website.

Emerging research also suggests a link between the gut microbiome and CRC risk. Maintaining a diverse and healthy gut microbiome through diet and potentially probiotics may offer additional protective benefits, though more research is needed in this area.
Improving Symptom Awareness: Listen to Your Body
Perhaps the most alarming aspect of the rising incidence of early-onset CRC is that symptoms are often dismissed or attributed to other, less serious conditions. Common symptoms include changes in bowel habits (diarrhea, constipation, or narrowing of the stool), rectal bleeding, abdominal pain, unexplained weight loss, and fatigue. Mint reports that many patients delay seeking medical attention because they don’t realize these symptoms could indicate cancer.
Dr. Karlitz urges both patients and healthcare providers to accept these symptoms seriously, regardless of age. “We need to destigmatize discussions about bowel health and encourage people to seek medical attention promptly if they experience any concerning changes,” he said. “Early diagnosis is critical for improving treatment outcomes.” The rising cases in Sri Lanka, as reported by Ada Derana, further highlight the need for increased awareness and early intervention.
The Younger Patient Perspective
The increasing prevalence of CRC in younger adults is challenging conventional wisdom. Men’s Health recently published an article urging younger individuals to be vigilant about potential symptoms and not dismiss them as simply “stress” or “dietary issues.”
The three pillars – optimized screening, lifestyle modification, and symptom awareness – represent a comprehensive strategy for tackling the rising rates of colorectal cancer. The next step involves widespread implementation of these strategies and continued research to better understand the underlying causes of this concerning trend. Further studies are planned to investigate the role of the microbiome and genetic predispositions in early-onset CRC.
