Does colon cancer result in colostomy bag?
National data indicate that approximately 50% of patients with rectal cancer from 2002-2004 received a colostomy. Specialized surgical teams can drastically reduce that rate, dropping percentages into the teens. For colon cancer, it is rare that a patient will require a planned colostomy.
What happens if they find a tumor during a colonoscopy?
Usually if a suspected colorectal cancer is found by any screening or diagnostic test, it is biopsied during a colonoscopy. In a biopsy, the doctor removes a small piece of tissue with a special instrument passed through the scope. Less often, part of the colon may need to be surgically removed to make the diagnosis.

Does tumor size determine colon cancer stage?
Conclusions: Tumor size proved to be an independent prognostic parameter for patients with colorectal cancer. Optimal cut-off values vary among different parts of the large bowel. Whereas prognostic significance is strong within the colon, it appears to be of minor value within the rectum.
Which cancer requires a colostomy bag?
A colostomy is done when part of your colon or rectum has been removed and the part that remains cannot function normally. A colostomy may be done as part of an operation to treat colorectal cancer.

We’re lucky to have such a good screening test for colon cancer – colonoscopy can not only detect tumors while they’re curable, but it can identify precancerous polyps which can be removed before they become cancerous.
What kind of Technology is used for colonoscopy?
In virtual colonoscopy, also known as computerized tomographic (CT) colonography, x-rays and virtual reality technologies are used to create three-dimensional images and videos of the lining of the colon and rectum.
