Canine Ear Cancer

Ear tumors can be a serious issue for a dog's owner. Without treatment, they can spread into various other parts of the body, such as the lungs or the brain. These tumors can occur on the flap of the ear or deep within the ear canal and require immediate veterinary treatment.

  1. Causes

    • There is no known cause of canine ear cancer. An article on the Fetch Dog website states that severe or reoccurring ear infections or inflammation may contribute to the development of cancerous cells.

    Symptoms

    • According to Dr. Bari Spielman of Pet Place (website), many dogs do not display any symptoms aside from a mass found in or on the ear. Some dogs may have visible changes of the ear skin, bleeding, discharge, odor and vestibular signs―such as loss of balance.

    Diagnosis

    • Dogs with any form of ear cancer will undergo several tests including blood tests, x-rays, radiographs of the skull, a biopsy of the affected tissue and a CT scan.

    Treatment

    • There are different options available depending on the type, size and location of the cancer within the ear. Options include surgical removal, cryosurgery, hyperthermia and radiation therapy.

    Prognosis

    • Prognosis of canine ear cancer will varies from poor to extremely good. The location of the tumor, whether metastasis (spreading) has occurred, the severity and the type of tumor all affect the potential outcome.
