Colorectal cancer originates in either the colon or the rectum and is a formidable opponent in the fight against cancer. However, early detection through regular screening serves as a potent tool in our fight against this disease and can help prevent colorectal cancer. The National Cancer Institute recommends screening for adults aged 45 years or more without symptoms but at an average risk of colorectal cancer. Those with a hereditary colorectal cancer syndrome or other risk factors may need to initiate screening at an earlier age.

Randomized clinical trials and cohort studies have demonstrated that colorectal cancer screening can significantly reduce mortality related to colorectal cancer. In other words, a simple test can be a lifesaver. We will now examine the appropriate time to initiate screening, the diverse range of screening tests available, and steps to choose the most suitable screening method for you.

When to Begin Screening for Colorectal Cancer

Screening for colorectal cancer is recommended for individuals aged between 45 and 75 years. Individuals with an average risk should commence colorectal cancer screening at age 45. However, those with certain risk factors may need to begin screening earlier.

But how does one ascertain their risk level?

Identifying Your Risk Level

Several risk factors can contribute to the development of colorectal cancer. Some of these include:

  • Older age

  • Family history of colorectal cancer

  • Certain genetic syndromes such as Lynch syndrome

  • Obesity

  • Diabetes

  • Consumption of red and processed meat

  • Tobacco use

  • Alcohol consumption

Understanding these risk factors can help individuals assess their risk for colorectal cancer and take appropriate preventive measures.

Age is one of the primary risk factors, with approximately one in four individuals over the age of 50 having polyps.

Assessing your personal and family history along with your lifestyle choices is key to determining your risk level. Apprehending your risk factors allows you to make knowledgeable decisions about the timing of screening and the most suitable screening method for you.

Tailored Screening for High-Risk Individuals

If you have a family history of colon or rectal cancer or other risk factors, you may need to undergo more frequent colon cancer screening, such as colonoscopy. Individuals with inflammatory bowel disease, like ulcerative colitis, should initiate colonoscopies at least 8 years after diagnosis and receive follow-up colonoscopies every 1 to 3 years.

Your healthcare provider can provide guidance on the screening option best suited for you, based on recommendations from the preventive services task force. They can also work out an appropriate screening schedule to follow, tailored to your individual risk profile. Communication with your healthcare provider is key to ensuring you receive the most accurate and beneficial screening recommendations.

A Closer Look at Colorectal Cancer Screening Tests

There are two kinds of tests for checking colorectal cancer: tests that check your stool and tests that look inside your colon and rectum. Stool-based tests are non-invasive and detect signs of cancer in a person’s stool, while visual examinations inspect the colon and rectum directly. Each test type comes with its unique set of pros and cons, which we will examine in the subsequent subsections.

Stool-Based Tests: Simple but Crucial

Stool-based tests are non-invasive screening tests for colorectal cancer that can be conducted in the comfort of one’s own home. Three principal stool-based screenings are the high-sensitivity guaiac fecal occult blood test (gFOBT), the fecal immunochemical test (FIT), and the stool DNA test. These tests help to accurately diagnose various diseases. Each test has its own set of pros and cons, which should be considered when choosing the most appropriate test for you.

The different types of stool tests for colorectal cancer detection include:

  1. High-sensitivity gFOBT: detects blood in the stool, with a sensitivity range of 0.50 to 0.75 for colorectal cancer detection.

  2. FIT: detects blood in the stool using antibodies instead of chemicals, with a pooled sensitivity of 0.74 and specificity of 0.94.

  3. Stool DNA test: identifies potential DNA alterations in cells that could signify the existence of colon cancer or precancerous states. The sole stool DNA test approved by the US Food and Drug Administration is a multitarget stool DNA test that also includes a FIT component, referred to as sDNA-FIT, with a pooled sensitivity of 0.93 for colorectal cancer detection.

If stool-based tests yield abnormal results, a colonoscopy is necessitated for additional assessment. Discussing these options with your healthcare provider is significant to determine the test that best fits your individual needs and risk factors.

Visual Examinations: The Direct Approach

Visual examinations provide a more thorough approach to detecting colorectal cancer, with tests such as colonoscopy, CT colonography, and flexible sigmoidoscopy. These tests enable healthcare providers to inspect the interior of the colon and rectum for any anomalous regions that may be cancerous or precancerous polyps. Research has demonstrated that visual examinations can detect colorectal cancer and the majority of polyps, rendering them a vital screening approach for early detection.

Colonoscopy is the most comprehensive and precise test for colorectal cancer screening. It is capable of detecting and eliminating polyps during the same procedure. However, it is an intrusive procedure and necessitates sedation or anesthesia, which may be uncomfortable and lengthy.

Virtual colonoscopy, also referred to as CT colonography, is a non-invasive imaging procedure that creates comprehensive visuals of the colon and rectum to spot any polyps or cancers. It requires bowel preparation but does not require sedation.

Flexible sigmoidoscopy is a less invasive procedure that examines the lower part of the colon and rectum but does not visualize the entire colon. It also requires bowel preparation but typically does not require sedation.

Each visual examination carries unique pros and cons that should be taken into account when choosing the test that fits best for you.

Preparing for Your Screening Test

Following the instructions provided by your healthcare provider is necessary before undergoing a colorectal cancer screening test. For example, prior to a colonoscopy or other visual examinations, you will need to adhere to a clear liquid diet and ingest a powerful laxative to empty and cleanse the colon.

For stool-based tests, no dietary restrictions are typically necessary. However, it is still important to follow your healthcare provider’s instructions to ensure accurate results. Proper preparation for your screening test can enhance the probability of early detection of any potential issues, which can have a significant impact on your health and well-being.

Navigating Insurance and Costs

When determining a colorectal cancer screening test, it is necessary to consider cost and insurance coverage. Insurance typically covers screening colonoscopies for colorectal cancer, including the cost of the procedure and sedation. However, there may be some services or charges that are not covered by insurance, so it’s important to review your specific insurance plan for further details.

Without insurance, the expense of common colorectal cancer screening tests can vary. A colonoscopy can range from $1,250 to $4,800, with an average cost of $2,750, while at-home tests such as Cologuard can cost approximately $24 per test. It is advisable to consult healthcare providers for specific pricing information and to explore financial assistance programs if necessary.

Making an Informed Choice: Screening Methods Compared

To make a knowledgeable decision about the most suitable colorectal cancer screening method for you, it is important to balance the pros and cons of each test. Stool-based tests, such as gFOBT, FIT, and stool DNA tests, are non-invasive and can be conducted at home. However, they may have a higher rate of false positives and may miss some cases of colorectal cancer.

Visual examinations, such as colonoscopy and virtual colonoscopy, provide a more thorough approach to detecting colorectal cancer but may be more invasive and require bowel preparation. Each test has its own set of pros and cons, so it’s essential to discuss these options with your healthcare provider to determine the best approach for your individual needs and risk factors.

Comparing the various available colorectal cancer screening methods enables you to make a knowledgeable decision about the most suitable test for you. It’s important to consider factors such as your risk level, personal preferences, and any potential barriers to undergoing the test, like costs or accessibility.

Talking to Your Doctor About Colorectal Cancer Screening

Consulting with your healthcare provider about colorectal cancer screening is necessary to determine the approach best suited for you. Your provider can assess your individual risk and suggest the most suitable screening option for you. Additionally, they will determine an appropriate screening schedule to follow. By discussing your preferences, concerns, and any questions you may have, you can work together with your healthcare provider to develop a screening plan that best meets your needs.

If you have a preference for a screening test that differs from the one recommended by your healthcare provider, it’s important to express your wishes and discuss the reasons behind your preference. Your healthcare provider can help you understand the advantages and disadvantages of each test and provide guidance on the most appropriate screening method for your specific situation.

Regular Screening: The Path to Prevention
