Difference Between Ct Scan And Colonoscopy

Similarly Colonoscopy is not indicated because of pain alone.If there is bowel irregularity or blood in stool Colonoscopy is reasonable to do. In your case I would watch /monitor for 4-6 weeks, then ...Read moreSee 1 more doctor answer

What is the difference in diagnostics between mri, cat scan and colonoscopy? Which one is best for identifying problems?
Depends: Mri and ct scans are noninvasive imaging techniques. They have their own inherent advantages and disadvantages, and to compare them would be too complicated here.

It is common to recommend a colonoscopy several weeks after the diverticulitis had healed, if you have not already had one. ...Read moreSee 2 more doctor answers

Start with : A skin test. If this is negative then TB is quite unlikely. You may react positive though if you've been vaccinated or been sensitized from previous contact.

Why so worried? : It sounds like you have already undergone an extensive evaluation. Rectal and colon cancer are very rare at your age. Typically, a flexible sigmoidoscopy is sufficient in your age group. Given your young age, and extensive studies, I think your risk is low. Are there other symptoms or lifestyle choices that make you worry about anal disease? ...Read moreSee 1 more doctor answer
?Early detection tes: CT scan is not a good Test for early detection of Colon Cancer, so Colonoscopy is the preferred test because it accomplishes 2 objectives...detect polyps/precursors of colon cancer and remove them at the same time which eliminates the risk of Polyps changing into cancer.
