How Do I Prepare For My Screening Procedure
Prior to a colonoscopy or flexible sigmoidoscopy, there are some steps you must take to prepare. Your doctor will provide you with specific preparation instructions, which may be similar to the following:
The day before your procedure, you may need to limit drinks to clear liquids. You may also be asked not to eat or drink anything after midnight the night before your test.
You will need to empty your colon before your test so that your doctor can see clearly into your colon. To do this, you may have to take a laxative or use an enema kit.
Your doctor may have you adjust your medication dosages or temporarily stop taking certain medications for your test.
Cologuard Vs Colonoscopy: Which One
Physicians who work in the field largely regard colonoscopy as the gold standard. Colonoscopy has the highest detection rate of small tumors and polyps, and It is the cancer screening that can prevent colon cancer by removing precancerous polyps.
“By removing polyps this can prevent a cancer from growing, and this is one of the best cancer prevention methods we have,” said Peter Garrett, MD, a radiation oncologist with Cancer Care Group in Indianapolis. Dr. Garrett is an independent provider who chooses to practice at Franciscan Health.
Colonoscopy remains the first recommendation for all eligible, average-risk patients, and stool-based testing if patients are unwilling to proceed with colonoscopy initially. High-risk or symptomatic patients should undergo colonoscopy without stool-based testing. Insurance often covers screening colonoscopies, but if an abnormality is found, it becomes a diagnostic colonoscopy, which may be more expensive per your plan.
What matters most is that all patients undergo age-appropriate colon cancer screening of some type and adhere to routine surveillance depending on their specific circumstances.
Can Hemorrhoids Cause A Positive Cologuard Test
Yes, hemorrhoids are one possible cause of false positive Cologuard tests.
Most inaccurate results occur because there is blood present in the stool, and hemorrhoids are one cause of blood in the stool. Diarrhea and menstruation are other possible causes.
For this reason, the National Institutes of Health recommends that you avoid taking a test if you are menstruating or have diarrhea or hemorrhoids .

Pro No Prep Work Or Anesthesia Necessary
Cologuard doesnt require the unpleasant bowel preparation, sedation or insertion of a scope that comes with a colonoscopy. Patients can eat and drink normally before they collect the stool sample at home, avoiding disruption of work and daily activities.
This can make Cologuard a great option for people who take blood thinners, have serious medical conditions or are not healthy enough for the colonoscopy procedure. Its also a great alternative way to reach patients in rural areas to help them keep up with colon cancer screenings without the hassle of driving long distances for an in-person visit.
Blood From Hemorrhoids Or Colon Cancer
Stools themselves are not bloody because the stool is formed in the colon .
Colon cancer can be present with bloody stools because the stool has time to mix with blood in the colon.
Blood on toilet paper can also be caused by any of the following:
The above four possible sources of minute bleeding can be aggravated by aggressive wiping or by using a paper towel to wipe rather than gentler tissue paper.
However, any rectal bleeding should be evaluated by a physician or gastroenterologist to determine whether any diagnostic testing is necessary to exclude a serious cause of bleeding, says Dr. Sengupta.
Another serious cause other than colon cancer or an ulcer is Crohns disease.
A bleeding hemorrhoid, though a nuisance, is not a serious medical condition but it should be treated and managed.
Dr. Senguptas research interests involve optimizing the care and outcomes of patients hospitalized with gastrointestinal bleeding. Specific interests include GERD, colon cancer screening and fatty liver disease.

What Dietary Restrictions Or Preparations Should I Take Before My Fecal Occult Blood Test
The fecal occult blood test, or FOBT, is a chemically sensitive test and does require you to restrict your diet a couple days before the test. This is because certain foods and medications can trigger false-positive or false-negative results.
False-positive This term is used by the medical community when a person tests positive for a condition or disease and does not have it. If you receive a false-positive from your home screening test, this means you test positive for cancer or blood in your stool when you in reality have neither.
False-negative Conversely, this result means you actually have the disease or condition and the test does not detect it. A false-negative stool test means the lab failed to detect blood or abnormal cells in your stool.
Many people can receive a false-positive result because they have blood in their stools from hemorrhoids or a bleeding ulcer in their upper intestinal tract. Other people may receive a false-positive result because they have consumed an iron supplement or iron-rich foods such as red meat that contain compounds that look like hemoglobin, the oxygen-carrying protein found in our blood.
In order to avoid these inaccurate results, your doctor may ask you to avoid certain foods and supplements before you take your test.
The fecal occult blood test carries the most restrictions due to the chemical reaction the test uses to detect blood in the stool. Many foods can interfere with this reaction and are listed below.
Cost And Insurance Coverage
On paper, there is an enormous difference in the cost of Cologuard versus the cost of colonoscopy. In the United States, the Cologuard kit is roughly $500, while the average cost of a colonoscopy is around $2,125.
Even so, your actual out-of-pocket costs may be the same. This is because both screening tests fall under the list of Essential Health Benefits prescribed by the Affordable Care Act .
EHBs are specific tests and procedures that under provisions of the ACA must be covered by health insurers in the United States, including Medicare, Medicaid, and private insurance.
This doesnt mean that there will be no out-of-pocket expenses for provider visits and other care-related costs. But studies have shown that the average out-of-pocket costs for colonoscopy are only around $79.

Why Use A Cologuard Test For Colon Cancer Screening
Because the stool-based tests are easier to complete, many patients opt for this method since some type of colorectal cancer screening is preferred to none at all. Current estimates suggest that 70 percent of eligible patients get a colon cancer screening of any kind.
“Some patients may choose to forego screening altogether if stool-based testing is not offered,” said Paul Broderick, DO, with Franciscan Physician Network Central Indiana Proctology in Martinsville. “The need for bowel prep, sedation and the costs and logistics of an outpatient procedure can be significant deterrents.”
Can You Feel A Polyp
Because most people with colon polyps do not experience any symptoms, you might not know you have a polyp until your doctor finds it during an examination of your colon. However, some people with colon polyps may experience: Rectal bleeding.

Should I Use Cologuard
Cologuard is approved for use in adults 45 and over who are at average risk of colon cancer. A person at average risk has about a 4% chance of developing colon cancer.
The vast majority of colon cancers are sporadic, meaning that the genetic causes of cancer happen by chance after a person is born. By contrast, 5% of colon cancers are inherited, meaning that the cancer-related genetic mutations are passed from one generation to the next.
Having genetic mutations for cancer doesnt mean you will get cancer but greatly increases your risk.
Will Cologuard Detect Polyps
Yes. A Cologuard can detect the presence of polyps in your colon through your stool. If your result indicates the presence of abnormal DNA or hemoglobin, it means there are suspected precancerous polyps in your colon. If precancerous polyps are present in your colon, the result of your Cologuard test will be positive.

Prevent Colon Cancer: The Top 3 Home Tests
Although a colonoscopy is still the best choice for detecting colorectal cancer and precancerous polyps, I know that some patients become uneasy even thinking about a colonoscopy. Thats why Im providing a brief description of the top 3 FDA approved at home colon cancer screening tests for those who would prefer a different option.
1. Cologuard Cologuard is a noninvasive, stool collection kit sent by mail to a testing lab. Results take about 2 weeks. Cologuard screens for colon cancer by testing for DNA biomarkers in your stool related to colon cancer or precancerous polyps. Its recommended to take this test every three years.
Cologuard detects 92% of cancers and 69% of high-risk precancerous polyps.
A patient can take this test in the comfort of their own home. No dietary restrictions or bowel preparation are needed for a Cologuard.
However, patients need to be aware this test can produce both false positive and false negative results for colon cancer and precancerous polyps. This means a patient can have a positive Cologuard but when the patient goes for a colonoscopy no cancer or precancerous polyps are detected. The same goes for false negative results. A patient can have a negative Cologuard but then have a colonoscopy that finds colon cancer or precancerous polyps.
For this colonoscopy alternative, you will need to fill out a form for your doctor to order this test.

No Cologuard Test Results Are Not 100% Accurate
In fact, false positives results happen in Cologuard tests frequently. Up to 10 percent of positive results from Cologuard test may be incorrect. The rate of false positives increases with age hence test results should be interpreted with caution in older patients.
Also, a negative Cologuard test result does not guarantee the absence of cancer. If you have a negative Cologuard test result, you will be advised by your doctor to undergo colonoscopy or any other colorectal cancer screening method to confirm your status.
