People refuse colonoscopies due to fear (of pain, discomfort, embarrassment, or bad news), the unpleasant bowel preparation, practical barriers (cost, time off work, needing a ride), a belief they are healthy or not at risk (no family history/symptoms), and concerns about procedure risks or privacy, despite it being a highly effective cancer screening tool.
What happens if I refuse the Colonoscopy? This is your choice and there might be alternative examinations we can use instead. Your plan of care and treatment may change, as it is possible that some important information will be unavailable.
Recently, survey results of more than 2,000 U.S. adults revealed that 7 in 10 Americans would avoid or delay getting a colonoscopy*. The findings further discovered 4 major reasons as to why they would avoid this potentially lifesaving screening.
Virtual colonoscopy is a special X-ray examination of the colon using low dose computed tomography (CT). It is a less invasive procedure than a conventional colonoscopy. A radiologist reviews the images from the virtual colonoscopy to look for polyps on the inside of the colon that can sometimes turn into colon cancer.
It's recommended that you have a colonoscopy performed every 10 years, beginning at age 45 and up to age 75. This is the recommendation for people who aren't at increased risk of colon cancer. If you have personal or family history of colon cancer or other cancers, talk to your provider.
But mainly, doctors are looking for precancerous or cancerous colon polyps, which are growths on the inside of the colon's lining. If the doctors spot polyps, they can quickly and painlessly remove them during the same colonoscopy.
Colonoscopies are widely used, but there is another option available: fecal tests. Both types of test attempt to find cancers and large polyps — growths on the wall of the colon — that occasionally turn into cancers. Cancers that are found early often can be cured when doctors simply cut them out.
CT colonography has a much lower risk of perforating the colon than conventional colonoscopy. Most people who undergo CT colonography do not have polyps and can be spared having to undergo a full colonoscopy which typically requires sedation.
What Happens if You Don't Get a Colonoscopy? If you skip a colonoscopy, you risk missing out on early detection of colorectal cancer and other gastrointestinal issues. This can lead to delayed treatment, potentially reducing the chances of successful intervention.
But their short answer: No, an anesthesiologist is not always necessary for a routine colonoscopy in healthy patients, either because sedation might not be needed at all or because a non-anesthesiologist can safely administer light sedation.
In this way, the doctor examines your entire large intestine twice. If they find something in the process that they need to remove or treat, this will add extra time. Colon polyps are common: they turn up in about 30% of routine colonoscopies. Although most are benign, it's standard procedure to remove them on sight.
Preparing for your colonoscopy:
Take the day off: It is recommended that you take the day off work on the day of your procedure. You should not make any important decisions for the rest of the day following the procedure. You should not drive for the rest of the day.
Signs You May Need a Colonoscopy Sooner
Persistent changes in bowel habits, such as diarrhea, constipation, or narrowing of the stool. Chronic abdominal pain or cramping. Unexplained weight loss. Iron-deficiency anemia or ongoing fatigue.
Home, stool-based tests can be part of a screening program — but should never replace colonoscopy, the 'gold standard' of colorectal cancer prevention. Colorectal cancer is one of the most treatable forms of cancer.
Belly Pain or Discomfort
This is the most common side effect of colonoscopy. You might feel cramping or bloating afterward. Your doctor may use air to inflate your colon so they can get a better view. They might use water or a suction device as well as certain surgical tools to take off a polyp.
In the past, only clear liquids were allowed on the day before your colonoscopy. These included broths, soft drinks, tea, black coffee, clear juices, Jell-O, and popsicles (except for red or blue). It's not surprising that colonoscopy patients consistently complain about their hunger throughout the prep day.
Early recognition of red-flag signs and symptoms (abdominal pain, rectal bleeding, diarrhea, and iron-deficiency anemia) may improve early detection and timely diagnosis of early-onset CRC.
“As a gastroenterologist, I've heard all the reasons for not getting screened,” says Dr. Pluskota. “Most often, people express anxiety or fear about getting a colonoscopy. They've heard that the prep is difficult and are afraid the procedure will be painful.”
More serious complications, such as infection, bleeding, or bowel perforation, may not be immediately apparent and can arise within a few days after the colonoscopy. Symptoms of these complications may include severe abdominal pain, persistent bleeding, fever, chills, or changes in bowel habits.
Colonoscopy is a method of screening for colorectal cancer. Doctors can also use a range of other invasive and noninvasive alternatives for screening. Alternatives to colonoscopy include sigmoidoscopy, which is a less invasive form of colonoscopy, and noninvasive methods, such as stool sample testing.
CT scans and colonoscopies are instrumental in preventive services and risk management. While an abdominal CT scan provides broader imaging, a colonoscopy offers an in-depth look into the inner lining of the large intestine and the option for polyp removal.
A virtual colonoscopy uses computed tomography (CT) or magnetic resonance imaging (MRI) to make a three-dimensional image of the inner lining of the large intestine (colon) and rectum. It can be used to screen for precancerous and cancerous growths in the colon or rectum (colorectal cancer), such as polyps or tumors.
The simple answer: not enough people are having colonoscopies. According to our doctors, “Almost all patients who get colorectal cancer do so because they have failed to get screenings. Almost all the colorectal cancers would be prevented if people had their recommended screenings.”
Screen for colon cancer.
If you're age 45 or older and at average risk of colon cancer — you have no colon cancer risk factors other than age — your doctor may recommend a colonoscopy every 10 years. If you have other risk factors, your doctor may recommend a screen sooner.
Unlike a traditional colonoscopy, which uses a scope put into the rectum and advanced through the colon, virtual colonoscopy uses a CT scan to take hundreds of cross-sectional pictures of the belly organs. The pictures are then added together to provide a complete view of the inside of the colon and rectum.
