The large intestine (colon) extends from the cecum to the anus and includes the ascending colon, the transverse colon, the descending colon, the sigmoid colon, and the rectum.

Cancer is shown in a section of the descending colon.

Surgery removes the section of colon that contains cancer.

The surgeon connects the end of the remaining section of the colon to an opening made in the skin. This creates a stoma.

Body waste passes from the colon through the stoma into a colostomy pouch, which is taped to your body.
