In brief: Yes/No

Blood tests may show a problem; however blood tests cannot diagnose bowel (eg colon) cancer. Low hemoglobin (anemia) may indicate bowel blood loss, but is not specific.
Additionally, colon ca has a tumor marker cea that is useful after a diagnosis is made, but cannot diagnose by itself.
