Colon and Rectal Cancer Diagnosis Expertise

Piedmont Cancer gives patients access to the personalized care they need. At Piedmont Cancer, the first step in treating colon and rectal cancer is to establish an accurate diagnosis.

Colorectal Cancer Symptoms

Some of the symptoms caused by colon and rectal cancers include changes in your bowel movement, including the presence of red or dark blood or a change in the appearance of your stool. Other symptoms include fatigue from anemia (blood loss), a constant urge to defecate, abdominal pain, change in bowel habits or weight loss. These problems suggest that the cancer may be more advanced so it is critical to see a specialist right away.

Colon cancer is sometimes discovered incidentally, when anemia is detected on a blood test or during a rectal exam or stool blood test in a doctor’s office.

Colonoscopy and Imaging for Diagnostic Testing


This test is performed by a specialist who has special training in the use of a long fiber optic tube to visualize the entire length of the large intestine. People undergoing the test must drink liquid that helps to clean, or prepare, the colon for the test. Patients are given sedatives during the test, and do not recall the details of the examination. If an abnormality is found, a biopsy can be performed during the procedure.


If colorectal cancer is diagnosed, computed tomography is useful to look for evidence that the tumor has spread within the chest and abdomen.

When colorectal cancer is suspected, biopsies of the abnormal tissue are performed. Typically this happens during the colonoscopy. The biopsy tissue is studied under the microscope by a pathologist to look for the presence of cancer.

The analysis of the biopsy tissue by the expert pathologist at Piedmont Cancer shows whether colorectal cancer is present or not, and if present, an estimate of how aggressive the tumor might be. This information is critical prior to discussions of treatment.
