A colonoscopy screening is an important part of preventive healthcare, designed to find and remove precancerous polyps before they can develop into colorectal cancer. Understanding when to start these screenings is crucial for early detection and treatment.
While the general recommendation has changed in recent years, your personal health history plays a significant role in determining the right time for you.
The recommended age for a first colonoscopy screening is 45 for individuals at average risk of colorectal cancer. In this blog, you will learn about the following:
- Average risk age: Begin screenings at age 45.
- Increased risk factors: You may need earlier or more frequent screenings.
- Screening saves lives: Early detection significantly improves outcomes.
When Should You Get Your First Colonoscopy Screening?
For individuals with an average risk of developing colorectal cancer, the American Cancer Society and other major health organizations now recommend starting regular colonoscopy screenings at age 45. This updated guideline reflects data showing an increase in colorectal cancer among younger adults.
If your first colonoscopy screening shows no polyps and you have no other risk factors, your doctor will likely recommend that you repeat the procedure every 10 years. This schedule helps ensure that any new growths are found and addressed promptly.
What If You Have a Higher Risk?
Certain factors can increase your risk for colorectal cancer, meaning you may need to start colonoscopy screenings earlier than age 45 or have them more often. It is important to discuss your personal and family medical history with your doctor to create a screening plan that is right for you.
Family History of Colorectal Cancer
A significant risk factor is having a close relative – such as a parent, sibling, or child – who has had colorectal cancer or certain types of polyps. If a first-degree relative was diagnosed before age 60, you should generally start your screenings 10 years before the age they were diagnosed.
Personal Medical History
Your own health history can also place you in a higher-risk category. Conditions that may require an earlier or more frequent colonoscopy screening schedule include:
- A personal history of colorectal cancer or certain types of polyps.
- A history of inflammatory bowel disease, such as Crohn’s disease or ulcerative colitis.
- A known or suspected genetic syndrome, like familial adenomatous polyposis (FAP) or Lynch syndrome.
Lifestyle Factors
Lifestyle choices can also influence your risk. Factors such as a diet low in fiber and high in red meat, a lack of regular physical activity, obesity, smoking, and heavy alcohol use can all contribute to an increased risk of colorectal cancer.
Why is a Colonoscopy Screening So Important?
A colonoscopy is considered the gold standard for colorectal cancer screening for a reason. It is unique because it is both a diagnostic and a therapeutic procedure.
During the exam, your doctor can not only view the entire colon to find polyps but also remove them at the same time. According to the Centers for Disease Control and Prevention (CDC), regular screening can prevent colorectal cancer or find it at an early, more treatable stage.
How Do You Prepare for the Procedure?
Proper preparation is essential for a successful colonoscopy. Your colon must be completely clean so that your doctor has a clear view.
Your healthcare provider will give you specific instructions, which typically involve:
- Following a special diet for a day or two before the exam.
- Drinking a liquid bowel-cleansing solution.
- Arranging for someone to drive you home afterward, as you will be sedated.
