As
previously mentioned this condition comes in two forms and it is
normally quite advanced before any symptoms are noticed. Although the
Liver is an amazing organ it can still continue to function
relatively normally even when a large proportion of it has been
affected by a cancerous tumor or growth.
The
Liver has a variety of functions - including producing bile which is
utilized to make digestion easier. As well as aiding the
digestive
system it also regulates the
storage and how Carbohydrates are used by your dog's body. This very
important organ also helps with the mobilization of fat and helps to
detoxify and excrete toxic substances in your dogs body. The Liver also
helps to synthesize the proteins found in your dogs blood system while
also helping to keep your pooches body temperature stable.
Metatastic
Liver Cancer in Dogs
Metatastic
Liver Cancer in dogs is when the Cancer has spread to other organs in
your dog's body. This is a very serious condition and will produce a
variety of symptoms. As previously mentioned Cancer that forms in the
Liver first (Primary) is actually very rare and the disease will
normally form somewhere else before it spreads to the Liver. Due to the
fact that the organ helps to filter blood any Cancer Cells
that are being passed around the body via the blood stream and then
through the Liver - this will then cause the cancer to develop in this
organ.
Primary
Liver Cancer in Dogs
Primary Liver Cancer refers to a Cancer that has developed in the
Liver as opposed to somewhere else. Primary Neoplasia refers
to a Tumor (Cancer) that forms in the Liver. In this case the Cancer is
normally malignant and has developed from Liver Cells (also referred to
as Hepatocellular Carcinomas). The Primary type can also develop benign
tumors that also develop from Liver cells - this type is referred to as
Hepatocellular Adenomas (Hepatomos). This type of the disease is more
common in older dogs - especially those aged of 10 years of age.
Causes...
The
main causes of Primary Liver Cancer in dogs are actually due to
environmental factors. This can include carcinogens from chemicals or
toxins. nasty food additives, preservatives, colorings and fillers,
food dyes and pesticides.
Symptoms...
The
symptoms of this condition depend on the area that the tumor has
affected. benign tumors that are situated in one place and have not
spread will often not lead to your dog becoming seriously ill. However,
if the tumor is large enough to have caused abdominal issues then your
pooch might show negative symptoms. A benign tumor that has become
particularly large and more intrusive can impact on other areas within
the abdomen especially if has started bleeding should it have been
ruptured. In very unusual cases a tumor might cause your dog to
experience low blood sugar and even hypoglycemia. More common symptoms
will normally include some of the following...
- Loss of appetite
- Vomiting
and sickness
- Tiredness and lethargy
(especially after exercise) or even just walking around the House.
- Your pooch might be
really thirsty and want to drink lots of water.
- Your dog might urinate
excessively.
- If your dog is
experiencing Anemia then you might notice that your pooch has pale gums.
- You may notice blood
in your dog's poop.
- The abdomen might
appear distended and out of shape
- Your pooch might start
breathing faster or even have difficulty breathing.
- Weight loss is another
symptom of the condition.
- Your pooch might have
skin that appears yellow - this is a sign of Jaundice.
Diagnosis
of Liver Cancer in Dogs...
As
previously mentioned sometimes the symptoms don't start to appear until
the Cancer has become more advanced. Sometimes the owner is the best
person to ask about unusual symptoms because even the smallest symptom
can be picked up on by a loving owner. Alongside speaking to the owner
the diagnosis of this disease may include the vet using some of the
following techniques...
- A complete physical
examination and look at the medical history.
- A CBC (Complete Blood
Count) may also be taken.
- An
abdominal X-ray might need to be undertaken to see if there is anything
causing the unusual symptoms.
- A
chest X-ray or abdominal Ultrasound scan might be used by the Vet to
make an accurate diagnosis.
- A
Biochemical profile might also be undertaken by the Vet. This is an
amazing procedure that involves the Vet taking a small sample of blood
- the blood sample is then sent to a Lab to be tested - this will
involve electrolytes, enzymes and lots of other molecules being tested
in Laboratory conditions. A Biochemical profile is a unique method used
by medical professionals to look at and examine the inside workings of
a dog's body.
- The
Vet might also undertake clotting tests.
- In
some scenarios the Vet might take a biopsy of the Liver.
- Urinalysis
- this is the chemical analysis of your dog's urine.
Liver
Cancer in Dogs - Treatment...
In
some cases surgery might need to be performed to remove the disease
tumor. If the tumor has spread to other areas of your dog's body then
your dog's chances of recovery and even survival are reduced
significantly. The Vet might need to treat secondary problems with IV
fluids (if your dog has become dehydrated) and even blood transfusions.
As mentioned previously the Liver is an amazing organ and can continue
to function with only twenty percent left after surgery. Chemotherapy
is sometimes used to treat metatastic cancers but is not particularly
effective when used to treat Primary liver cancer in dogs.
