A regular colonoscopy is the gold standard for colon cancer screening for the vast majority of patients. Most colon and rectal cancers may be detected with this check before they create symptoms.
Other screening tests are available to assist find polyps, blood, or other abnormal cells in the colon. Consult your doctor to determine which is best for you.
A colonoscopy is a medical procedure that examines the large intestine, or colon. It can detect polyps (small growths), which are a symptom of cancer, as well as other issues that may lead to colorectal cancer.
The American Cancer Society advises that average-risk people get at least one screening colonoscopy by the age of 45. A doctor may recommend one more often for high-risk patients.
A gastroenterologist performs a colonoscopy by inserting a flexible tube with a camera at the end (a colonoscope) into your rectum and inspecting the whole colon. The test is often performed as an outpatient procedure.
A sedative is usually administered to make you more comfortable throughout the process. The doctor will also push air into your colon, which widens it and allows the doctor to see more clearly.
Most patients have slight bloating or gas following the surgery, but these symptoms usually subside within a day. Your doctor will write you an antibiotic prescription to prevent any infections that may emerge as a result of the surgery.
Colonoscopy is a painless and efficient method of screening for colorectal cancer. It has a high sensitivity and specificity for diagnosing neoplasia, and it can detect and remove polyps before they turn cancerous. However, it is not cheap or easily accessible to the general public, making large screening programs challenging.
A intestinal scope, also known as a flexi-sig, is a technique that can assist your doctor evaluate symptoms and monitor your health. To view within the lower section of your big bowel, a tiny tube with a light and camera on one end is used.
If you experience rectal bleeding, stomach discomfort, or changes in your bowel habits, your doctor may offer this test. Because your bowel must be empty for the exam, you will normally get an enema (liquid that causes you to go to the bathroom) or a rectal laxative suppository prior to the exam.
The sigmoidoscope, or flexible tube, is then inserted into your anus and slowly guided into your rectum and into the sigmoid colon by the doctor. Your doctor can inspect the tissues and lining of your sigmoid colon and rectum using the video pictures delivered by the scope's camera.
The sigmoidoscope can be used by your doctor to acquire tissue samples or polyps for biopsy. If a biopsy is required, you will have little rectal bleeding during the surgery. However, in most cases, this is not an issue and may be managed with a simple drug.
A double-contrast barium enema is an X-ray treatment used to detect aberrant colon growths. Colorectal cancer, polyps, and diverticular disease are all detected using this test.
A radiology technician inserts a tiny tube into your rectum and injects a liquid containing the silver-white metallic substance barium. The barium covers the lining of your colon, making it more visible on an X-ray.
The radiologist then injects air through the same tube to improve the image. This is a DCBE (dual-contrast barium enema).
Adenomas bigger than 1.0 cm were identified in 23 colonoscopic exams, and related barium enema findings were positive in 11 investigations. The detection rate was greater for adenomas measuring 0.5 to 1.0 cm than for those measuring 0.6 to 1.0 or more than 1.0 cm.
A full colonoscopy is the gold standard for screening. However, in other cases, such as when there is a big mass or tumor, a colonoscopy is not possible. Double-contrast barium enema may be an option for colorectal screening in these patients. It can aid in the detection of adenomas that are not apparent on a colonoscopy and may aid in the prevention of colorectal cancer. Consult your doctor to determine whether this testing is appropriate for you.
