Blood Tests

A complete blood count (CBC) is done to see if you are anemic. Even if you are not weakened or fatigued because of anemia, there may have been enough bleeding due to the tumor to demonstrate a low hemoglobin blood count (anemia).

Liver function tests are done to see if the cancer has spread to the liver or bone (metastasis).

Tumor markers, such as carcinoembryonic antigen (CEA), are elevated in some cases of colon cancer. These tests are used to help establish the diagnosis of colon cancer and to monitor for recurrence after the colon cancer is treated if tumor markers are elevated.
