| The right side of the colon includes the cecum, ascending colon and proximal transverse colon and cannot be reached by flexible sigmoidoscopy. |
| A physician could recommend a colonoscopy, fecal occult blood testing, a double-barium enema, flexible sigmoidoscopy, or a general rectal exam. |
| Immunological tests and flexible sigmoidoscopy should be evaluated as potential new tests in screening for colorectal cancer. |
| However, some patients experience significant discomfort when sigmoidoscopy is performed without sedation. |
| They should receive one or a combination of four screening tests, including fecal occult blood test, sigmoidoscopy, colonoscopy, and barium enema. |
| Persons with at least one positive stool card were offered further diagnostic testing that most commonly included barium enema, flexible sigmoidoscopy or full colonoscopy. |
