The Growing Concern Among Younger Adults

Colorectal cancer is the third most common cancer diagnosed in both men and women in the United States. Thanks to increased awareness and screenings for early detection and treatment of colorectal cancer, overall rates have declined in adults aged 50 and older. Yet, there has been a notable increase in cases among individuals under 50. This shift has prompted the Centers for Disease Control and Prevention (CDC) to adjust screening guidelines, now recommending that adults at average risk begin regular screenings at age 45.  

Understanding the Risk Factors

While cases are rising among younger individuals, the risk increases as you age. Other risk factors include:

• Family history of colorectal cancer or polyps
• Diet high in red and processed meats and low in fiber
• Physical inactivity
• Obesity
• Smoking
• Alcohol consumption

Emerging research is also exploring potential links between microplastics and the rise in colorectal cancer among younger populations.  

Colon Cancer is Preventable

Taking charge of your health can significantly reduce the risk of colorectal cancer. Here are some proactive steps you can take to reduce your risk:

• Eat a variety of colorful fruits and vegetables, and add beans and whole grains into your meals. These foods are rich in fiber, which supports digestion and gut health. 
• Exercise regularly to maintain a healthy weight and promote overall well-being.
• Limit alcohol consumption, which can damage the lining of the colon and rectum, potentially leading to cancer.
• Avoid tobacco.

The Lifesaving Power of Screenings

Screenings are essential for the early detection and prevention of colorectal cancer. They can identify precancerous polyps, allowing for removal before they turn into cancer. Early-stage detection significantly improves treatment outcomes.

If you’re at average risk for colorectal cancer, you should begin regular screenings at age 45. Several screening methods are available. Talk to your provider about what’s best for you based on your family history and other risk factors. He or she may recommend you begin screenings earlier and possibly have them more frequently.

It’s also important to recognize the warning signs of colorectal cancer such as:

• Changes in bowel habits
• Blood in your stool
• Persistent abdominal pain or discomfort
• Sudden, unexplained weight loss
• Fatigue

Most importantly, don’t be shy about talking to your doctor if you’re experiencing any symptoms that concern you!

The Bottom Line

Colorectal Cancer Awareness Month serves as a vital reminder of the importance of understanding risk factors, making informed lifestyle choices and following recommended screening guidelines. By staying informed and proactive, we can lessen the impact of colorectal cancer on our communities. Most important of all, start the conversation now. Talk to your doctor about any concerns or potential risks and plan for recommended screenings.
