Why screening could save your life.
Colorectal Cancer: Know the Facts
Colorectal cancer is one of the most common cancers in the U.S. and the second leading cause of cancer-related deaths [1]. However, it is also one of the most preventable and treatable forms of cancer when detected early. Colorectal cancer begins in the colon or rectum, often starting as small, benign growths called polyps. Over time, some polyps may develop into cancer. Fortunately, with regular screenings, these polyps can be detected and removed before they become cancerous.
When caught in its early stages, colorectal cancer has a survival rate of over 90% [2]. Unfortunately, many people do not experience symptoms in the early stages, which is why proactive screening is essential.
Who Should Get Screened?
The American Cancer Society and the U.S. Preventive Services Task Force recommend that adults at average risk begin regular colorectal cancer screenings at age 45 [3]. However, certain factors may increase your risk and require earlier or more frequent screening:
- A family history of colorectal cancer or polyps
- A personal history of inflammatory bowel diseases like
Crohn’s disease or ulcerative colitis - Genetic conditions such as Lynch syndrome or familial
adenomatous polyposis (FAP) - Lifestyle factors, including a diet high in processed foods and red meat, smoking, excessive alcohol consumption, obesity, and lack of physical activity
If any of these risk factors apply to you, discuss with your doctor whether you should begin screening earlier or use more advanced testing methods.
Screening Methods: What Are Your Options?
Several screening options are available, allowing you to choose a method that suits your lifestyle and health needs. The most common screening tests include:
• Stool DNA Test (e.g., Cologuard®) (every 3 years): This test detects genetic changes in stool samples that may be linked to cancerous growths.
• Flexible Sigmoidoscopy (every 5 years): Similar to a colonoscopy, but only examines the lower part of the colon.
• CT Colonography (Virtual Colonoscopy) (every 5 years): A non-invasive imaging test that creates 3D pictures of the colon and rectum to detect abnormalities.
Your healthcare provider can help determine which screening option is best for you based on your risk factors and personal preferences.
Recognizing the Symptoms
Although colorectal cancer may not present symptoms in its early stages, there are warning signs to be aware of, including:
• Persistent changes in bowel habits, such as diarrhea, constipation, or narrowing of stool
• Blood in the stool or rectal bleeding
• Abdominal pain or cramping that does not go away
• Unexplained weight loss
• Fatigue or weakness
If you experience any of these symptoms, don’t wait – schedule an appointment with your doctor as soon as possible.
Preventing Colorectal Cancer
While regular screenings are the most effective way to prevent colorectal cancer, adopting a healthy lifestyle can also significantly lower your risk. Consider these tips:
• Eat a balanced diet: Focus on fiber-rich fruits, vegetables, whole grains, and lean proteins while limiting red and processed meats.
• Stay physically active: Aim for at least 30 minutes of moderate exercise most days of the week.
• Maintain a healthy weight: Obesity increases the risk of colorectal cancer, so maintaining a balanced diet and regular exercise is key.
• Avoid smoking and excessive alcohol consumption: Both have been linked to an increased risk of colorectal cancer.
• Get enough Vitamin D and Calcium: Studies suggest that these nutrients may help protect against colorectal cancer.
Take Action Today
March is Colorectal Cancer Awareness Month, making it the perfect time to take charge of your health. If you’re 45 or older (or at higher risk), schedule your screening today. Encourage friends and family to do the same – early detection saves lives!
Don’t delay – talk to your doctor about the best screening option for you and make your health a priority.
