| What is the difference between a colonoscopy and sigmoidoscopy? |
|
The difference between colonoscopy and sigmoidoscopy is related to which parts of the colon each can examine. Sigmoidoscopy allows doctors to view only the lower part of the colon, while colonoscopy allows doctors to view both the upper and lower sections. Recent research suggests that colonoscopy is superior to flexible sigmoidoscopy as a colon cancer screening method. |
