Dr. Bryan Kleinman discusses rising colorectal cancer rates

The recent death of actor James Van Der Beek at age 48 has brought national attention to a concerning health trend: more adults under 50 are being diagnosed with colorectal cancer. Providers across the country, including here at Optum Medical Care, are working to raise awareness and encourage earlier discussions about screening.

In a recent interview with Radio Catskill, Dr. Bryan Kleinman, a board‑certified gastroenterologist with Crystal Run Healthcare powered by Optum, discussed the rise of colorectal cancer in younger adults and why early screening is more important than ever.

Why younger adults are seeing higher rates

“Colorectal cancer is becoming an increasingly common cancer in patients under 50,” Dr. Kleinman shared. Over the past decade, cases in this age group have increased by nearly 3% each year.

This shift led national organizations to lower the recommended age for routine colonoscopy from 50 to 45. Even so, Dr. Kleinman notes that he is seeing patients in their early 40s with advanced polyps — and in some cases, cancer.

Researchers are studying several possible contributors, including dietary patterns low in fiber, higher consumption of processed foods, rising obesity rates, alcohol use, tobacco use and potential changes in the gut microbiome.

Colonoscopy remains the most effective screening tool

“Colonoscopy is still the gold standard,” Dr. Kleinman said. The procedure allows providers to examine the entire colon and remove polyps before they become cancerous.

Colonoscopy is performed under sedation, so patients are comfortable and typically recover quickly. Most return to normal activities the following day.

Tackling the most common fear: the prep

Many people hesitate because they’re nervous about colonoscopy preparation. Dr. Kleinman emphasized that while the prep requires avoiding solid foods for 24 hours and drinking a laxative solution, most patients report afterward that it was manageable — and worth it for the peace of mind.

When to start screening if there’s a family history

For individuals with a family history of colorectal cancer, screening should begin earlier than age 45. Providers typically recommend starting at age 40 or 10 years before a family member’s diagnosis.

For people with inherited conditions or other concerns, Dr. Kleinman encourages early conversations with a primary care clinician or specialist.

What you can do today to lower your risk

Lifestyle also plays a role in prevention. Eating more fiber, fruits and vegetables, staying physically active, and limiting processed meat, alcohol and tobacco use can help support long-term digestive health.

Looking ahead, Dr. Kleinman is hopeful about future advancements. “Everybody would love to see a blood test to detect any type of cancer,” he said. “Those things are potentially on the horizon.”
