Diagnosis of Canine Colon Cancer

A veterinarian looking for a diagnosis of canine colon cancer will ask about the dog's symptoms and check for physical signs of tumors. He may then also perform any of a series of tests, including X-rays, ultrasounds, PET scans, blood tests and lab analysis of liquid drawn from a tumor. These tests can also rule out any other cause of symptoms, such as canine colitis.
