Osteosarcoma is a type of bone cancer specific in dogs. It is one of the
most misunderstood ailments in dogs to date, simply because there is an
extensive lack in information and knowledge about the cancer.
It is known however that of the bone malignancies somewhere around ninety
percent is attributed to Osteosarcoma. However, when it comes to canine
tumors, the bone cancer is only attributed to roughly five percent of those
cases.
Osteosarcoma is a very aggressive bone cancer, at this time scientists,
researchers, and veterinarians do not believe that it is preventable. In
fact, it seems to be a hereditary aspect in breeds. Some breeds are more
prone to the bone cancer than others. For example, breeds of dogs in the
giant category, such as Irish Wolfhounds, Saint Bernards, and Great Danes
have the highest chance of developing this diseases.
Increased risk comes with any large breed of dog. Dogs such as Shepherds,
Labradors, Boxers, Golden Retrievers, and Rottweilers, or any dogs weighing
more than eighty pounds have a higher chance of developing Osteosarcoma.
Osteosarcoma does not seem to be extremely common in smaller dogs, such as
those seventy-five pounds or less, but it does seem to be more common in
male dogs than in female dogs.
It is suggested that before breeding your dog, that you take a close look at
the medical history of both dogs. It seems that the Osteosarcomas cells
transfer from parents and is more associated with hereditary aspects than
anything else.
Osteosarcomas Symptoms
Typically, any symptoms of the bone cancer will be display in the affected
area. For the most part, the location of the cancer will typically be around
the knee or underneath the elbow. Swelling of the area will be extremely
noticeable and your pet will likely favor the limb affected. In other words,
they will refrain from use or limited use of the limb.
Visiting the veterinarian can help in proper diagnosis. It is likely the vet
will perform x-rays of the site, as well as perform a biopsy to ensure that
it is Osteosarcomas and not another type of tumor or infection.
Treating Osteosarcomas
Because this bone cancer is extremely aggressive, the measure taken for
treatment will also be extremely aggressive. In most all cases, once a tumor
has been diagnosed as bone cancer it is likely that amputation of the limb
will need to be performed. However, there have been rare circumstances and
instances in which surgeries have been the answer, saving the limb from
amputation, again this is extremely rare.
Because it is cancer, chemotherapy is the most common course taken after
amputation. One of three different types of chemotherapy drugs are used,
which may be Doxorubicin, Cisplatin, or Carboplatin.
Caring for your best friend means being aware of any afflictions they may be
more susceptible to and the best course of treatment. Knowing what to look
for will better help you watch for the signs.
