Tumors on the Liver of Dogs

Tumors on the liver of dogs is a rare canine hepatic tumor. The tumor can be benign or malignant and can be caused by environmental or genetic factors.

  1. Prevention of Liver Tumors in Dogs

    • Tumors in dogs cannot be totally prevented, however by employing certain practices, the risk can be diminished. Regular check ups, required vaccinations, good nutrition and hygiene are all measures that can be employed to maintain a robust dog and healthy immune system. A healthy immune system can stave off canine illness and sometimes liver tumors.

    Liver Tumors in Dogs are Rarely Primary

    • Tumors on the liver of dogs are usually not primary tumors. They are usually a result of metastatic tumor somewhere else in the body. Malignant primary liver tumors are referred to as hepatocellular carcinomas which form from cells of the liver.

    Environmental Factors May Be Responsible

    • Tumors on the liver of dogs may be caused by exposure to certain chemicals that are known to be carcinogenic. The liver is the primary organ that breaks down toxic chemicals. Chemicals may become even more toxic after this process. Pesticides and rancid pet food can produce cancer causing toxins that can contribute to liver tumors in dogs.

    Virus Can Be a Contributor

    • Viruses and infections have been shown to initiate liver tumors in humans and animals. Viruses can causes liver cells to mutate and initiate a malignancy. Most viruses are not implicated in tumors in dogs, but certain infections such as canine hepatitis can contribute to tumors on the liver of dogs.

    Advancing Age as a Risk Factor

    • Tumors are more prevalent in dogs older that 10 years. There is a slightly higher incidence of liver cancer in the male dog. Tumors can be benign and commonly do not cause symptoms unless the tumor grows to where it presses on surrounding organs.

    Signs, Symptoms and Treatment of Liver Tumors in Dogs

    • Signs and symptoms of tumors on the liver of dogs include abdominal distention, vomiting, loss of appetite, weakness, difficulty breathing, rapid respiration, pale gums, jaundice and weight loss. Not all of these signs will indicate a tumor in the dog, but early diagnosis is important in the prognosis. Diagnosing canine liver tumors include a history and physical, complete blood count, abdominal x-rays, chest x-rays and liver biopsy. Treatment can include surgical intervention, IV fluids, blood transfusions and chemotherapy.
