Rising Colorectal Cancer Rates in Younger Adults: A Growing Concern

Colorectal cancer, once primarily a disease of older adults, is now increasingly affecting younger men and women. In fact, it’s the leading cause of cancer death for Americans under 50. The recent deaths of actor James Van Der Beek, at age 48, and previously, Chadwick Boseman at 43, have brought this alarming trend into sharp focus.

The Increasing Incidence in Younger Adults

While overall colorectal cancer cases and deaths have slightly decreased in recent years due to increased screening, diagnoses are rising among individuals in their 20s, 30s, and 40s. According to the American Cancer Society, more than 158,000 cases of colorectal cancer will be diagnosed in the U.S. This year, and an estimated 3,890 people under age 50 will die from the disease.

Who is at Risk?

Risk factors for colorectal cancer include:

• Obesity
• Lack of physical activity
• A diet high in red or processed meat and low in fruits and vegetables
• Smoking
• Heavy alcohol use
• Inflammatory bowel disease
• A family history of colorectal cancer

Dr. John Marshall of Georgetown University’s Lombardi Comprehensive Cancer Center notes that many young patients diagnosed with colorectal cancer don’t have these typical risk factors, suggesting other factors may be at play.

Symptoms to Watch For

It’s crucial to be aware of potential symptoms, which include:

• Blood in stool or rectal bleeding
• Changes in bowel habits (diarrhea, constipation, or narrowing of stool) lasting more than a few days
• Unintended weight loss
• Cramps or abdominal pain

James Van Der Beek initially attributed a change in his bowel movements to his coffee consumption, highlighting how easily early symptoms can be dismissed. “Don’t ignore symptoms. Acquire it checked,” emphasizes Dr. Marshall.

Screening Recommendations

Current medical guidelines recommend that average-risk individuals begin colorectal cancer screening at age 45. Though, individuals with a higher risk should discuss earlier screening with their doctor. Screening options include:

• Yearly stool-based tests
• Colonoscopies every 10 years (if no problems are found)
• A newer blood test for adults 45 or older

What’s Driving the Increase?

The exact cause of the rise in colorectal cancer among younger adults remains unknown. Researchers are investigating potential factors, including changes in gut bacteria (the microbiome) and differences in tumor location within the colon.

Prevention and Lifestyle Factors

Adopting a healthy lifestyle can help reduce your risk. This includes:

• Eating a diet rich in fruits, vegetables, and whole grains
• Limiting red and processed meat consumption
• Engaging in regular physical activity
• Maintaining a healthy weight
• Avoiding smoking and excessive alcohol consumption

A recent study showed that a three-year exercise program improved survival rates and reduced cancer recurrence in colon cancer patients.

Early detection and prevention are key to combating this growing health threat. If you experience any concerning symptoms, consult your healthcare provider promptly.
