Researchers agree that fecal testing, colonoscopy, and sigmoidoscopy are all effective at detecting colorectal cancer. The most appropriate screening method varies, depending on a person’s risk factors and preferences.
What are ways to check for colon cancer?
The tests used to screen for colorectal cancer are described below.
- Colonoscopy. …
- Computed tomography (CT or CAT) colonography. …
- Sigmoidoscopy. …
- Fecal occult blood test (FOBT) and fecal immunochemical test (FIT). …
- Double contrast barium enema (DCBE). …
- Stool DNA tests.
Is Fit Test better than colonoscopy?
A single FIT test detects about 73 percent of colorectal cancers. But because you use FIT every year, 10 screenings over 10 years make it just as good as one colonoscopy every 10 years, Wender said.
Can colon cancer be diagnosed without a colonoscopy?
However colonoscopy remains the most sensitive test for colorectal cancer screening and the identification of precancerous polyps. Stool based tests, such as Cologuard or FIT, are reasonable alternatives for patients who are unable or unwilling to undergo a standard colonoscopy. Screening saves lives.
Is there an alternative to colonoscopy prep?
Half Lytely is a bowel preparation kit that must be prescribed by your doctor before your colonoscopy. It is a combination of two laxatives and is taken after following a clear liquid diet.

Is poop in a box as good as a colonoscopy?
The stool test is cheaper and less invasive, experts say. When it comes to colon cancer screening, an annual stool test may be as effective as colonoscopy for people who don’t have risk factors for the disease, a new study suggests.
Are cologuard tests reliable?
How Accurate is the Cologuard test? Cologuard can detect 92% of cancers but only 42% of large precancerous polyps. Cologuard is better at detecting cancer than FIT (92% vs 70% for FIT), but the false positive rate is higher. Cologuard has a 12% false-positive rate, and that rate increases as people age.
Where is the pain in colon cancer?
Colon cancer is cancer of the last part of the large intestine. Colon cancer pain is generally felt as vague abdominal pain or cramps.
How can you detect colon cancer at home?
At-home screening options
- FIT: The fecal immunochemical test, or FIT, uses antibodies to detect blood in the stool, and it’s about 79% accurate at detecting colon cancer. …
- Cologuard: A pricier option than FIT, Cologuard is about 92% accurate at detecting colorectal cancer.
