Should I Get Screened For Colon Cancer?
5 min read
Colon cancer is a formidable adversary that, when detected early, can often be effectively treated or even prevented altogether. Colon cancer screening plays a crucial role in identifying abnormalities in the colon before they develop into cancer or detecting cancer in its early stages when it is most treatable. In this blog post, we will delve into the significance of colon cancer screening, available screening methods, and why it is essential for individuals to prioritize their health through regular screenings.
Understanding Colon Cancer: Colon cancer, also known as colorectal cancer, typically begins as small, noncancerous clumps of cells called polyps. Over time, some of these polyps can become cancerous. Colon cancer often develops without symptoms in its early stages, making regular screening an invaluable tool in preventing its progression.
The U.S. Preventive Services Task Force (Task Force) recommends that adults 45-75 years old be screened for colorectal cancer. The decision to be screened if you are older than 75 should be made on an individual basis. If you are older than 75, you should talk to your primary care doctor about screening. People younger than 45 years old or older than 75 years old who are at an increased risk of getting colorectal cancer should talk to their doctor about when to begin screening, which test is right for them, and how often to get tested.
The Importance of Screening:
Early Detection Saves Lives: Early detection is the key to successful treatment. Colon cancer screening can identify precancerous polyps or early-stage cancer, allowing for prompt intervention and increasing the chances of a positive outcome.
Prevention through Polyp Removal: Many screening methods not only detect cancer but also enable the removal of precancerous polyps. This act of prevention can significantly reduce the risk of developing colon cancer in the first place.
Risk Assessment and Personalized Care: Screening allows primary care doctors to assess an individual's risk factors for colon cancer. Based on this assessment, personalized care plans can be developed, including more frequent screenings for those at higher risk.
Common Colon Cancer Screening Methods:
Colonoscopy: A colonoscopy is considered the gold standard for colon cancer screening. It involves the insertion of a thin, flexible tube with a camera into the colon, allowing for a detailed examination of the entire colon. This procedure not only detects but also enables the removal of polyps.
Guaiac-based fecal occult blood test (gFOBT): This test uses the chemical guaiac to detect blood in the stool. It is done once a year.
Fecal Immunochemical Test (FIT): The FIT is a non-invasive test that detects hidden blood in the stool via the detection of antibodies, which can be an early sign of colon cancer. It is a simple and cost-effective screening option, although a positive result may warrant further investigation with a colonoscopy.
FIT-DNA test (aka stool DNA test): This test combines the fecal immunochemical test (FIT) with a test that detects altered DNA in the stool. For this test, you collect an entire bowel movement and send it to a lab, where it is checked for altered DNA and for the presence of blood.
CT Colonography (Virtual Colonoscopy): This imaging test uses computed tomography (CT) to create detailed images of the colon. While it is less invasive than traditional colonoscopy, it still requires bowel preparation and may not be suitable for everyone.
Flexible Sigmoidoscopy: Similar to a colonoscopy but focusing on the lower part of the colon, flexible sigmoidoscopy is another option for screening. It may be recommended in combination with other tests.
Most major health insurance plans will cover the cost of these screening tests. It is important you call your health insurance carrier to confirm this. For patients who are underinsured or uninsured, websites such as colonoscopyassist.com can provide affordable solutions.
Conclusion:
Colon cancer screening is a powerful tool in the fight against one of the most common and deadly forms of cancer. It empowers individuals to take charge of their health, identify potential issues early on, and, in many cases, prevent the development of cancer altogether. It is crucial for everyone, especially those with risk factors, to engage in open and proactive discussions with their primary care doctor about colon cancer screening. By making informed choices and prioritizing regular screenings, we can collectively work towards a future where colon cancer is not just treatable but preventable.
