Colorectal cancer, or colon cancer, is a common yet preventable form of cancer. Regular screenings can identify precancerous growths or detect cancer in its earliest stages, when treatment is most effective. Despite its significance, many people delay or avoid screening due to fear or lack of awareness. Here’s more information on how colon cancer screening can save lives:
Colon Cancer and Its Risks
Colon cancer begins when cells in the colon or rectum grow uncontrollably. It often starts as noncancerous growths called polyps. If these polyps are not detected and removed, they can develop into cancer over time. Early stages of colorectal cancer may not show any symptoms, which is why screening is so helpful.
Several factors can increase a person’s risk of developing this type of cancer. For instance, age is a significant risk factor. A personal or family history of colorectal cancer or polyps also raises the risk.
Screening’s Role in Early Detection
Screening is the process of looking for cancer or pre-cancer before symptoms appear. For colorectal cancer, screening plays a key role in saving lives. The main goal is to find and remove polyps before they turn into cancer. When colon cancer is found at an early stage, it is highly treatable. This may lead to less invasive treatments and better outcomes for patients. Detecting and treating colon cancer early is one of the most effective ways to prevent deaths from this disease. Following recommended screening guidelines is a helpful step in managing your health.
Types of Screening Tests
Several types of screening tests are available to detect colorectal cancer. These tests vary in methodology and frequency of use, and your healthcare provider can help determine which option is best for you. Here are some of them:
- Stool-based tests: These tests analyze stool samples to detect blood or abnormal DNA that may indicate the presence of cancer.
- Colonoscopy: A procedure where a long, flexible tube with a camera is used to examine the interior of the colon and rectum for abnormalities.
- Flexible sigmoidoscopy: Similar to a colonoscopy, but focuses on the lower part of the colon and rectum.
- CT colonography (virtual colonoscopy): A noninvasive imaging test that uses CT scans to produce detailed images of the colon and rectum.
Consulting with your doctor about these options can help you receive the most appropriate screening for your individual health needs.
Screening Eligibility and Frequency
Screening recommendations depend on your individual risk level. For people with an average risk, screening typically begins at age 45. The frequency of screening depends on the type of test you choose. For instance, a colonoscopy is usually recommended every 10 years, while stool-based tests may be needed every one to three years.
People with a higher risk may need to start screening earlier and frequently. Higher-risk individuals include those with a family history of colorectal cancer or a personal history of inflammatory bowel disease. It is helpful to discuss your personal risk factors with a healthcare provider to determine the best screening schedule for you.
Schedule Your Colorectal Cancer Screening
Regular screening is a fundamental part of preventing colorectal cancer. By detecting the disease early, treatment can be more effective, and lives can be saved. Understanding your risk and the available screening options is the first step toward protecting your health. Contemplate your personal health history and discuss it with your doctor. Contact a trusted specialist near you to schedule an appointment today and learn more about the screening option that is right for you.
