Screening for Colorectal Cancer (CRC)
Age 45 is now the age to start screening for colorectal cancer among all average risk adults according to 2021 guidelines from the American College of Gastroenterology. This is an important change from earlier guidelines that used to recommend starting at age 50 for most people and age 45 for African Americans only. Your gastroenterologist can diagnose colorectal cancers at an earlier stage, find colon polyps early so they can be safely removed, and help to prevent colorectal cancers.

Overview
- What is Colorectal Cancer?
o Colon cancer is a disease in which cancer cells grow in the large intestine also called the colon.
o Rectal cancer is a type of colon cancer that grows in the rectum which is the part of your intestine closest to the anus.
o Colon and rectal cancers grow from abnormal tissue called polyps.
- How common is Colorectal Cancer?
o In the United States, colon and rectal cancer is the third most common cancer.
o The lifetime risk of colon and rectal cancer for men is 1 in 23 and for women is 1 in 25.
o Around 50,000 people will die from colon and rectal cancer each year.
o The risk of colon and rectal cancer appears to be rising in younger people.
- Who should get screened for Colon and Rectal Cancer?
o Screening lowers your change of getting sick or dying from colon or rectal cancer. o Everyone ages 45 to 75 years old should be screened for colon and rectal cancer. o Some people have higher risks of cancer. For example, if you have family members with colon or rectal cancer or if you have an Inflammatory Bowel Disease you may need to be screened at a younger age.
• How can I get screened for Colon Cancer?
Colonoscopy is a one-step test that looks for growths called polyps in your entire colon (large intestine) and rectum using a colonoscope. Your doctor can both detect and remove polyps during colonoscopy and prevent colorectal cancer. Colonoscopy is the most commonly performed gastrointestinal procedure in the United States. Colonoscopy with removal of polyps offers long term protection against developing colorectal cancer or dying from it.
ACG recommends colorectal cancer screening in average-risk individuals between age 45 and 75 years to reduce pre-cancerous growths called advanced adenomas, reduce colorectal cancer, and reduce death from colorectal cancer.Two-Step Screening Tests: Stool-Based Tests
These tests detect blood or altered DNA in the stool as a first step. A positive result would lead to the second step of colonoscopy for further examination.
FIT Test
Fecal Immunochemical Tests (FIT) detects hidden blood in the stool. The stool FIT test is typically performed on an annual basis. A positive test requires a follow-up colonoscopy.
Multitarget Stool DNA (mtsDNA)
Multitarget stool DNA test is a non-invasive screening for colorectal cancer. It looks for abnormal DNA associated with colon cancer or precancerous polyps. This test is more sensitive than the FIT test, but your chance of getting a false positive may increase with advancing age. According to the manufacturer's recommendations, if the mtsDNA test is negative, repeat screening occurs in three years. If the mtsDNA test is positive, the second step of colonoscopy is required. (At this time the only FDA-approved mtsDNA is Cologuard.®)
Tests for Individuals Who Cannot or Will Not Have a Colonoscopy or FIT, or Are Not Candidates for Colonoscopy
CT Colonography and Colon Capsule
At this time, CT colonography and colon capsule are options for individuals unwilling or unable to undergo colonoscopy or FIT, provided that the tests are locally available and reimbursed by insurers for screening. It is important to note that both tests will still require a follow-up colonoscopy if positive.

Screening
- Who should get screened for Colon and Rectal Cancer?
o Screening lowers your change of getting sick or dying from colon or rectal cancer. o Everyone ages 45 to 75 years old should be screened for colon and rectal cancer. o Some people have higher risks of cancer. For example, if you have family members with colon or rectal cancer or if you have an Inflammatory Bowel Disease you may need to be screened at a younger age.
• How can I get screened for Colon Cancer?
o Colonoscopy:
Tier 1: A colonoscopy is a procedure where a camera looks inside the colon is called a colonoscopy.
During a colonoscopy, your doctor can find a cancer.
Your doctor also can find and remove polyps which can prevent cancer
To prepare for a colonoscopy you will adjust your diet in advance and will drink medications (a bowel prep) to clear stool from your colon.
You are usually given medications to make sure you are comfortable and/or asleep during the colonoscopy and will need a ride home.
o Flexible Sigmoidoscopy:
A procedure where a camera looks inside part of the colon (the left side) and can diagnose a cancer or remove polyps in this area if seen. It is done with or without medications to make you sleep.
It is a Tier 2 test that should be repeated every 5 years.
o Stool Tests:
There are two stool tests that can changes in the stool that may be from a cancer.
You collect a small stool sample at home in a kit or cup that has been given to you and then you return the sample to a laboratory either through the mail or in person.
If the test is abnormal (positive) you will need a colonoscopy.
FIT: One test is call called FIT which stands for “Fecal Immunochemical Test” and can detect blood in the stool.
This is one of the top recommended colon cancer screening tools (Tier 1).
This test should be done every year.
FIT-DNA:
The other test is called a FIT-DNA test. The only current FDA approved test available it Cologuard®.
This test can detect blood or abnormal DNA in the stool.
This test should be done every three years.
This is a Tier 2 test.
o Computerized Tomography Colonography (CTC) is a radiology study where you drink medicine (bowel prep) to clear stool from your colon and then you go through a machine that takes pictures of your intestines to look for polyps or cancer. A small tube goes into the rectum to inflate the colon with air. You are awake during the study.
This is a Tier 2 test.
If the test is abnormal you will need a colonoscopy.
This test should be repeated every 5 years.
o Colon capsule is a study where you swallow a small camera that takes pictures of your intestines from the inside and a physician will review the images and is looking for polyps or cancer.
This is a Tier 2 test.
If the test is abnormal you will need a colonoscopy.
This test should be repeated every 5 years.
Symptoms
- • What are the symptoms of Colorectal Cancer?
o Most early colon and rectal cancers do not cause symptoms. This is why screening for colorectal cancer is so important!
o Sometimes people will see blood in the toilet or in their stool due to a cancer.
o People can get belly (abdominal) pain or won’t be able to go to the bathroom (constipation) from a colon or rectal cancer.
o Sometimes people will have low blood counts (anemia) from a cancer which makes them tired.
o Weight loss that is not from another reason can also be from a cancer.
o You should see your doctor right away if you have any of these symptoms.
- • Why should you get checked for Colon and Rectal Cancer even if you have no symptoms?
o Abnormal tissue (adenomas or polyps) can grow for years before turning into cancer.
o Finding these adenomas before they turn into cancer you can prevent a cancer.
o Finding a cancer in an early stage is easier to treat and can help you live longer than if you find a cancer that has spread.
- • Why should you get checked for Colon and Rectal Cancer even if you have no symptoms?
Risk Factors
- • What are the risk factors for colon and rectal cancer?
- o Age:. The older you are the higher the risk of colon and rectal cancer. All people with no risk factors other than age, should get screened at age 45 years old.
- o A family history of colon or rectal cancer: If you have a first degree relative (mother, father, sister, brother, child) or multiple other relatives with colon or rectal cancer, or polyps called “advanced adenomas” you are at increased risk of colon or rectal cancer.
You may be recommended to get a colonoscopy at a younger age and have them done more frequently.
You should discuss your screening plan with your Gastroenterologist.
- o Inflammatory Bowel Disease.
(IBD) in the colon such as Ulcerative Colitis or Crohn’s Disease can increase your risk of colon or rectal cancer.
If you have IBD you should discuss your colon and rectal cancer screening with your Gastroenterologist.

Colonoscopy FAQs
- What is Colonoscopy?
Colonoscopy is a procedure which enables a physician (usually a gastroenterologist) to directly image and examine the entire colon. It is effective in the diagnosis and/or evaluation of various GI disorders (e.g. colon polyps, colon cancer, diverticulosis, inflammatory bowel disease, bleeding, change in bowel habits, abdominal pain, obstruction and abnormal x-rays or CT scans) as well as in providing therapy (for example, removal of polyps or control of bleeding). It is also used for screening for colon cancer. A key advantage of this technique is that it allows both imaging of abnormal findings and also therapy or removal of these lesions during the same examination. This procedure is particularly helpful for identification and removal of precancerous polyps.
- What is a Colonoscope?
A colonoscope is a flexible and steerable instrument to evaluate the entire colon (large intestine). The large intestine is approximately 3 – 4 feet long. A colonoscope is engineered such that biopsies of suspicious areas can be obtained, and polyps (which may turn into cancer) can be removed.
- What is my risk of developing colon cancer if I live in the United States?
Your lifetime risk (defined as life to 85 years old) is approximately 6% (male or female). Your risk is roughly doubled if one (1) first degree relative (parent, sibling or child) had colon cancer or polyps after age 50, and is higher if the cancer or polyps were diagnosed at a younger age or if more members of your family are affected. Certain inherited disorders, for example, polyposis syndromes and hereditary non-polyposis colorectal cancer, can increase your risk of developing colon cancer, but those are rare. Other important risk factors include obesity, cigarette smoking, inflammatory conditions in the colon such as Crohn’s, colitis and ulcerative colitis, and excessive alcohol consumption. Your doctor is in the best position to discuss whether your personal or family history suggests one of those conditions.
- Has colonoscopy been shown to be effective in preventing cancer of the colon and saving lives?
Yes. Colonoscopy accomplishes this by detecting and removing polyps, and detecting early cancers. Recent data show that both the number of new cases of colon cancer (incidence) and deaths from the disease are decreased when colonoscopy is performed according to established guidelines (see Question 11).
- If colonoscopy is so effective at detecting polyps, colon cancer and saving lives, why aren't more people having it?
The most common reason patients cite for not getting a colonoscopy is that their doctor did not discuss it with them. The next most common reason is fear or avoidance of the preparation (“prep”), which involves taking a laxative which causes temporary diarrhea for several hours. In addition, many people are simply unaware that they need colon cancer screening.
- What is the "prep" for colonoscopy like? How many different preps are out there?
This is an important obstacle in the eyes of many patients to getting a colonoscopy, but it need not be!
There are a variety of preparation methods for colonoscopy ranging from liquids (of varying quantity) with or without enemas, to pills, which rid your colon of feces. A clean colon is essential to allow for a careful examination for polyps or other abnormalities. Your doctor can discuss and prescribe the most appropriate preparation method for you, taking into account various factors such as your age, personal preferences, kidney function and physical stamina.
- The most popular preparation used for colonoscopy involves drinking a volume of solution of polyethylene glycol (PEG). This solution causes a diarrhea that effectively rids the colon of its contents. Various fruit flavors are available and patients have several hours to drink it. Usually a patient will have clear liquids the day of the preparation (day before the colonoscopy) and then take half of the prep in the late afternoon or that evening. The other half is done approximately 5 hours before coming in for the test the following day. Patients are encouraged to drink a lot of fluids and to continue clear liquids up until 2 hours before their scheduled procedure. Before going to bed, many doctors also prescribe a laxative pill (e.g. Dulcolax®) that helps with the evacuation process.
- Smaller volumes of solution (e.g. MoviPrep®, HalfLytely®) or pill preparations (e.g. OsmoPrep®) have also recently become available with similarly good outcomes to PEG for people who dread the thought of large volumes of liquid.
- Another preparation involves a phosphate solution (called Fleet® Phospho-soda) which consists of two (2) rounds of phosphate rich liquid of 45ml each the night before and day of the exam. It is essential to drink at least 2 quarts of water with these preps to replace losses.
- Alternatively, a phosphate tablet preparation of about 30 pills is available and is also very effective for colon cleansing and is preferred by some patients. This preparation also requires that you drink at least 2 quarts of water to replace losses.
Phospho-soda® prep should be avoided in patients with significant heart or kidney problems, in elderly patients who have difficulty maintaining hydration and with caution in patients with significant liver problems
The best method of colonic preparation should be discussed with the gastroenterologist so that a method that suits the patient’s preference may be selected.
- Is colonoscopy painful? Will I be sedated?
No, colonoscopy is usually not painful! Almost all colonoscopies can be performed using “intravenous sedation” or “twilight sedation” in which you are very drowsy, but comfortable and still breathing on your own. The most common type of sedation also has a mild amnesiac effect, so most patients do not even remember the procedure! Your doctor can discuss with you the best form of sedation to suit your needs.
- Will my insurance pay for this procedure?
Medicare (and most third party payers) will pay for colonoscopy for colon cancer screening, thanks to the hard work of advocacy groups and the efforts of national organizations such as the American College of Gastroenterology (ACG). Regrettably, a recent study showed a low compliance rate for screening (less than 30%) among Medicare patients.
- Are there any complications from colonoscopy?
Yes, but potential complications are associated with virtually every form of testing done in medicine. Clearly, colonoscopy has been found to be extremely safe when performed by a well trained physician such as a gastroenterologist. Although quite rare, most complications are related to sedation administration (cardiac and respiratory problems); the colon may also become partially torn (perforated) and this may require surgery. Rarely, bleeding from polyp removal or from the procedure itself may require additional treatment such as hospitalization and/or blood transfusions. As one reads about these procedures, the reader should weigh these low risks against the far more frequent complication of developing colon cancer if appropriate testing is NOT done.
- When should I have a colonoscopy?
If you have no colorectal symptoms, family history of colon cancer, polyps or inflammatory bowel disease you should have your first exam at age 45 whether you are a man or a woman since colon cancer affects both EQUALLY! Recent evidence suggests that African Americans should begin screening earlier at the age of 45.
If one or more first degree relative (parent, sibling or child) has had a precancerous polyp or colon cancer, the general guideline is to begin colon cancer screening 10 years younger than the youngest age of the family member with colon cancer, or age 40, whichever is younger. There are additional guidelines for suspected or confirmed rare syndromes, and you should discuss these options with your doctor.
Questions and Answers about Quality in Colonoscopy
- Why is quality important in colonoscopy?
Although colonoscopy has been available in clinical practice for more than 40 years, only in the past 15 years has awareness developed that the success of colonoscopy in preventing colorectal cancer and minimizing complications is very dependent on the skill and competence of the colonoscopist. Colonoscopists differ substantially in the number of precancerous polyps they detect during colonoscopy and in how often they perform colonoscopy in response to both normal and abnormal findings. Awareness of these differences led the U.S. Multisociety Task Force on Colorectal Cancer in 2002, as well as a joint task force of experts from the American College of Gastroenterology and American Society of Gastrointestinal Endoscopy in 2006, to propose quality indicators that colonoscopists can use to measure how effectively and safely they perform colonoscopy. Obviously, patients have an interest in undergoing the most effective and safe colonoscopy possible, and achieving these goals requires a colonoscopist who is committed to high quality.
- Does the quality of examination differ among colonoscopists from different specialties?
Studies have shown average performance of colonoscopy by gastroenterologists to be superior to that of primary care physicians in three different areas of colonoscopy performance. First, three population-based studies have found that gastroenterologists performing colonoscopy are less likely to miss colorectal cancer than are primary care physicians who perform colonoscopy. This may reflect the more extensive training that gastroenterologists receive in this procedure and their higher volumes of colonoscopy in practice. Second, gastroenterologists’ patients are less likely to incur serious complications during colonoscopy, such as perforation or making a hole in the colon, compared to primary care physicians. Third, gastroenterologists are less likely than both primary care physicians and general surgeons to perform colonoscopy at intervals that are considered too short according to current guidelines. Whether this difference reflects a lack of confidence among primary care physicians and general surgeons in the quality of their colonoscopy or lack of awareness of current guidelines is unknown.
- Is there variation in quality of performance among members of the same specialty?
Even though gastroenterologists have on average the highest level of training and their examinations have been shown on average to be superior to primary care physicians, there is considerable variation among gastroenterologists in their detection rates of precancerous polyps. Therefore, it is essential that every colonoscopist, regardless of specialty, makes measurements to establish that their examinations are effective. It is very reasonable and appropriate for patients to ask questions of their colonoscopist about whether quality measurements are being made and their results.
- How can I be sure that I will receive a careful examination of my colon?
The measurement that best reflects how carefully colonoscopy is performed is a doctor’s "adenoma detection rate." This rate is defined as the percentage of patients age 50 and older undergoing screening colonoscopy, who have one or more precancerous polyps detected. This rate should be at least 25% in men and 15% in women. A secondary measure of careful examination is that doctors should have an average withdrawal time of at least six minutes. The withdrawal time is the time it takes to remove the scope from the colon. This interval is important because this is the phase of colonoscopy when most doctors actually examine the colon systematically for polyps. It is perfectly reasonable to expect doctors to have measured their adenoma detection rate and to record their withdrawal time. It is also reasonable to ask for a copy of the colonoscopy report that documents that the colonoscope was advanced to the very beginning of the colon and that the landmarks of that portion of the colon (called the "cecum") have been documented by notation in the report and by photography.
- Why is bowel preparation for colonoscopy important, and what can I do to make sure my colon is thoroughly cleansed for the procedure?
Colonoscopy is a video examination of the colon. The video camera and the colonoscope, like any other video camera, cannot see through solids. Therefore, the colon must be thoroughly cleansed to provide the doctor the best opportunity possible for a thorough and detailed examination.Be sure to pick up and read your written bowel preparation instructions at least several days before your colonoscopy. Go over the instructions and make sure you have all of the materials needed to complete the preparation.The most effective bowel preparations involve "split" dosing of the laxatives, in which half of the preparation is taken on the morning of the examination, usually 4 to 5 hours before the time of the scheduled colonoscopy, and completed at least 2 to 3 hours before that time. If you are scheduled at 7 or 8 in the morning, this will mean getting up very early to take the second half of the preparation. If the instructions call for split dosing, do not alter the timing of the doses. It is worth the inconvenience of getting up in the middle of the night to make sure that you have a very effective preparation. The timing of the second dose in relationship to the colonoscopy is critical. If too long an interval is allowed between the end of the second half of the preparation and the timing of the colonoscopy, mucus and secretions will come out of the small intestine and stick to the cecum and right colon.
- Summary
To ensure an effective and safe colonoscopic examination, find a well-trained colonoscopist who is committed to making quality measurements. It is fair to ask the colonoscopist to be sure to do a slow and careful examination and to provide a copy of the report that documents and photographs the complete extent of examination. Take the bowel preparation instructions seriously. Pick up the written instructions early, read them early, and follow them carefully. When colonoscopy is done carefully and with an effective preparation, it is a very powerful cancer prevention technique.
Your Doctor has Ordered a Colonoscopy: What Questions Should You Ask?
- Is the doctor performing your colonoscopy a Gastroenterologist?
A Gastroenterologist is a specialist in gastrointestinal diseases and has received special training in colonoscopy. Gastroenterologists perform more colonoscopies by far than any other specialty. Non-gastroenterologists are five times more likely to miss colorectal cancer during colonoscopy than Gastroenterologists.1
1 Rex DK, Rahmani E, Haseman JH, et al. Relative sensitivity of colonoscopy and barium enema.
- What training in colonoscopy did the doctor receive?
Proper training in colonoscopy is necessary not only to increase the chance that the procedure can be completed and any necessary treatments applied, but also to be sure that abnormal results can be properly interpreted. The American Society for Gastrointestinal Endoscopy recommends that persons performing colonoscopy complete a fellowship program in gastroenterology or receive training in colonoscopy during a surgical residency.
- How many colonoscopies has the doctor performed?
How many perforations has the doctor had?Many Gastroenterologists have performed many thousands of colonoscopies. A colonoscopist should know the rate at which their procedures have been associated with a perforation or making a hole in the colon. This rate should certainly be below 1 in 500 examinations and many experts have rates of perforation well below 1 in 1000.
- How often does your doctor complete the colonoscopy?
Experienced colonoscopists reach the very beginning of the large intestine (the cecum) in more than 90% of cases and in more than 95% of patients who are undergoing screening. Screening is the process of checking people who have no symptoms for colon polyps and cancer.
- Can the doctor remove polyps from your colon?
Persons performing colonoscopy must be trained in the removal of polyps. Although even Gastroenterologists may refer a patient with a large polyp to a special expert in the removal of polyps, a trained colonoscopist can remove the overwhelming majority of routine polyps.
What is a gastroenterologist?
- What is a Gastroenterologist?
A Gastroenterologist is a physician with dedicated training management of diseases of the gastrointestinal tract and liver.
- What is Gastroenterology?
Gastroenterology is the study of the normal function and diseases of the esophagus, stomach, small intestine, colon and rectum, pancreas, gallbladder, bile ducts and liver. It involves a detailed understanding of the normal action (physiology) of the gastrointestinal organs including the movement of material through the stomach and intestine (motility), the digestion and absorption of nutrients into the body, removal of waste from the system, and the function of the liver as a digestive organ. It includes common and important conditions such as colon polyps and cancer, hepatitis, gastroesophageal reflux (heartburn), peptic ulcer disease, colitis, gallbladder and biliary tract disease, nutritional problems, Irritable Bowel Syndrome (IBS), and pancreatitis. In essence, all normal activity and disease of the digestive organs is part of the study of Gastroenterology.
- Training
A Gastroenterologist must first complete a three-year Internal Medicine residency and is then eligible for additional specialized training (fellowship) in Gastroenterology. This fellowship is generally 2-3 years long so by the time Gastroenterologists have completed their training, they have had 5-6 years of additional specialized education following medical school.
Gastroenterology fellowship training is an intense, rigorous program where future Gastroenterologists learn directly from nationally recognized experts in the field and develop a detailed understanding of gastrointestinal diseases. They learn how to evaluate patients with gastrointestinal complaints, treat a broad range of conditions, and provide recommendations to maintain health and prevent disease. They learn to care for patients in the office as well as in the hospital.
Gastroenterologists also receive dedicated training in endoscopy (upper endoscopy, sigmoidoscopy, and colonoscopy) by expert instructors. Endoscopy is the use of narrow, flexible lighted tubes with built-in video cameras, to visualize the inside of the intestinal tract. This specialized training includes detailed and intensive study of how and when to perform endoscopy, optimal methods to complete these tests safely and effectively, and the use of sedating medications to ensure the comfort and safety of patients. Gastroenterology trainees also learn how to perform advanced endoscopic procedures such as polypectomy (removalof colon polyps), esophageal and intestinal dilation (stretching of narrowed areas), and hemostasis (injection or cautery to stop bleeding). Importantly, Gastroenterologists learn how to properly interpret the findings and biopsy results of these studies in order to make appropriate recommendations to treat conditions and/or prevent cancer. Some Gastroenterologists also receive directed training in advanced procedures using endoscopes such as endoscopic biliary examination (endoscopic retrograde cholangiopancreatography or ERCP), removal of tumors without surgery (endoscopic mucosal resection or EMR), placement of internal drainage tubes (stents) and endoscopic ultrasound (EUS). This provides them with the training necessary to non-surgically remove stones in the bile ducts, evaluate and treat tumors of the gastrointestinal tract and liver, and provide minimally invasive alternatives to surgery for some patients.
The most critical emphasis during the training period is attention to detail and incorporation of their comprehensive knowledge of the entire gastrointestinal tract to provide the highest quality endoscopy and consultative services. The final product is a highly trained specialist with a unique combination of broad scientific knowledge, general Internal Medicine training, superior endoscopic skills and experience, and the ability to integrate these elements to provide optimal health care for patients.
This advanced fellowship training is overseen by national societies committed to ensuring high quality and uniform education. These groups include the American Board of Internal Medicine, the American College of Gastroenterology, the American Gastroenterological Association, and the American Society for Gastrointestinal Endoscopy. These groups carefully scrutinize the educational experience of each program to ensure that every Gastroenterology trainee receives the highest quality training. Once fellows successfully complete their training they are considered “Board Eligible.” They are then qualified to take the Gastroenterology board certification test administered by the American Board of Internal Medicine. Once they have successfully completed this examination they are “Board Certified.”
- FACG, FACP — What do all the letters after your doctor's name mean?
Some Gastroenterologists receive special recognition from national societies when they demonstrate extraordinary achievement in research, teaching, or other unique service to the field of Gastroenterology. The American College of Gastroenterology and the American College of Physicians designate such physicians as “Fellows” and the suffixes FACG and FACP are added to denote these honors. This means that these physicians have fulfilled the respective organizations’ rigorous requirements to gain this added distinction.
- What makes Gastroenterologists different?
The unique training that Gastroenterologists complete provides them with the ability to provide high quality, comprehensive care for patients with a wide variety of gastrointestinal ailments. Gastroenterologists perform the bulk of research involving gastrointestinal endoscopic procedures as well as the interpretation of results, and are considered experts in the field. Studies have shown that Gastroenterologists perform higher quality colonoscopy examinations and comprehensive consultative services when compared to other physicians. This translates into more accurate detection of polyps and cancer by colonoscopy when performed by Gastroenterologists, fewer complications from procedures and fewer days in the hospital for many gastrointestinal conditions managed by trained gastroenterology specialists. It is this ability to provide more complete, accurate, and thorough care for patients with gastrointestinal conditions, which distinguishes Gastroenterologists from other physicians that provide some similar services.
