What Technique Is Best for Your Colorectal Cancer Screening?
There are other techniques that might be more suitable for colorectal cancer screening, even though colonoscopy is currently thought of as the gold standard.
The second most prevalent cause of cancer-related death in the nation, according to the National Cancer Institute, is colorectal cancer. Experts claim that many of those fatalities may have been prevented.
Colorectal cancer is one of the cancers for which a reliable screening tool is available. One explanation is that colorectal cancer, which may be identified by screening tests and removed before it spreads, almost invariably results from precancerous polyps in the colon or rectum.
Furthermore, colorectal screening helps with early cancer discovery, when treatments are most successful. According to the Cleveland Clinic, the five-year survival rate for colorectal cancer is approximately 90% when it is detected early.
Since doctors can actually see within the colon to check for abnormalities during a screening colonoscopy, which involves threading a camera through the colon, it has always been thought of as the gold standard screening method for colorectal cancer.
However, not everyone is able or ready to go through this treatment for a variety of reasons. The preparation for a colonoscopy, which includes a liquid diet before the procedure and drugs to cleanse the colon, can occasionally terrify patients or take too much time. Sometimes people are unwilling to take the test because they are terrified of it. Colorectal screening was difficult to obtain during the pandemic since facilities were shut down due to infection risk, which may have contributed to an increase in the disease’s incidence and delayed diagnoses.
All individuals between the ages of 45 and 75 should be checked for colorectal cancer, according to the U.S. Preventive Services Task Force (USPSTF), which provides colorectal screening recommendations. The USPSTF recommends that each case-by-case determination be made when screening persons 76 years of age and above.
While a colonoscopy is unquestionably the best method for detecting colorectal cancer, there are alternative methods available if you are unable or unable to have one.
What Sorts of Colorectal Cancer Screening Are There?
The American Cancer Society divides colorectal screening tests into two major categories.
- Visual tests Scopes are used during virtual colonoscopies, sigmoidoscopies, and colonoscopies to view the colon.
- Testing based on faeces Doctors examine excrement to look for polyps or colorectal cancer.
Every strategy has benefits and drawbacks. A screening is the most crucial step. These are some of the elements that you and your doctor will talk about before choosing a screening method.
- What you prefer do you have any concerns about getting anaesthesia? Do you have the time and means of transportation required for colonoscopy preparation and treatment?
- Your personal or family history of colorectal polyps or cancer. A colonoscopy may be suggested by your doctor if there is a family history of colon cancer.
- Additional medical issues less thorough screening may be required for you to be treated for some conditions.
- You may be more susceptible to colorectal cancer if you have certain genetic disorders, such as Lynch syndrome. Colonoscopy may be the most effective screening tool for you if you have genetic disorders.
- Your access to medical care Doctors can accommodate your insurance’s coverage limits.
Colonoscopy: The Gold Standard in Screening
A colonoscopy enables medical professionals to view the rectum and colon, which are both parts of the large intestine. To observe specific areas of the digestive system, doctors introduce a lighted tube with a camera connected into the rectum. The ability to diagnose issues and remove precancerous polyps simultaneously is one advantage of the treatment.
For those at moderate risk, the American Cancer Society suggests a colonoscopy every 10 years. If you have risk factors for colorectal cancer, such as a family history or a genetic mutation that increases your risk, you might need to undergo screening at a younger age and more frequently.
Colonoscopy Disagreement?
Recent studies sparked a debate about colonoscopy tests.
The advantages of colonoscopy screening have been the subject of some debate since a sizable European study that was published in October 2022 in the New England Journal of Medicine. According to the findings, the death rates among individuals who were invited to be examined for a colonoscopy and those who received normal treatment were essentially identical ten years later.
Only 42% of those who were asked to have a colonoscopy actually underwent the procedure, which is an important fact that helps to explain the results.
According to Douglas A. Corley, MD, PhD, MPH, a research scientist at the Kaiser Permanente Northern California Division of Research in Oakland, California, “The other patients, who did not accept, were not examined.” “This study merely permitted an assessment of the potential efficacy of a programme for inviting individuals to colonoscopies. It did not assess colonoscopy effectiveness directly.
Colonoscopies decreased the chance of dying from colorectal cancer by nearly 50% when the study’s researchers only looked at those who underwent the screening.
According to the American Cancer Society, preventive cancer screenings, including colonoscopies, are the greatest and most reliable strategy to save lives.
“As a result, the American Cancer Society advises adults starting at age 45 to undergo colorectal screening, which includes a colonoscopy. There is no justification for changing course. According to the group, routine cancer screenings ought to be a component of good health.
Modular Sigmoidoscopy
While a flexible sigmoidoscopy is a process comparable to a colonoscopy, the entire colon is not examined during this operation. A flexible instrument with a light and a camera is put into the rectum and moved through the lower portion of the colon during this examination. With a sigmoidoscopy, medical professionals can see the entire rectum and less than half of the colon.
It is likely that a flexible sigmoidoscopy won’t find cancer or polyps deeper in the colon because it doesn’t allow doctors to see the whole colon.
According to the Centers for Disease Control and Prevention, a flexible sigmoidoscopy is a helpful screening test when performed every five years or every ten years if it is paired with an annual faecal test (CDC).
Colonoscopy online (CT Colonography)
A virtual colonoscopy is a test that mimics the preparation for a traditional colonoscopy while being non-invasive. Instead of using a scope to see within the colon, doctors create images of the colon using X-rays and CT scans. According to the Mayo Clinic, a virtual colonoscopy can be just as good as a standard colonoscopy at identifying cancer and the majority of polyps when done properly. According to the CDC, this test should be carried out every five years as a colorectal cancer screening method.
Stool Examinations Stool examinations are performed to identify anomalies in faeces. There are various kinds, including:
Test for faeces immunochemical (FIT) In order to find blood in the faeces, FIT employs antibodies. It serves as a screening tool and is done once a year.
FIT-DNA analysis this examination combines FIT with a method that looks for unusual DNA in the faeces. Once every three years, it is completed.
Faecal occult blood test using guaiac (gFOBT) The chemical guaiac is used in this test to find blood in the faeces. Once a year is the recommended frequency, according to experts.
When done as advised, these [stool] tests are believed to be equally beneficial in reducing mortality from colorectal cancer, according to Dr. Corley. To attain the highest screening rates, the majorities of medical facilities provide both colonoscopies and stool testing.

Conclusion:
Even though most people don’t enjoy getting screened for colorectal cancer, doing so can help save lives.
You shouldn’t be required to pay for colorectal cancer screening tests either. The Affordable Care Act requires Medicare and private insurance providers to cover colorectal screening tests for eligible adults, according to the American Cancer Society. You should see your provider about unique benefits.
It is a good idea to discuss the various colorectal screening tests with your doctor. Choosing your path of action without waiting to be reviewed is crucial.
Corley claims that screening tests are only helpful if they are finished. “The best test is the one that gets the job done,”
