samples were submitted for histopathology and diagnosed as osteosarcoma. Osteosarcoma
is the most common bone tumor of dogs. Osteosarcoma has a high rate of spread to the lungs
and other tissues. At the time of diagnosis, most osteosarcomas have already spread to the
lungs. The early cancer cells are often not detectable on x-rays until they have grown
to a significant size. Because of the high rate of spread, the treatment of choice for
osteosarcoma is limb amputation and follow up chemotherapy. Withouth limb amputation,
many dogs will experience spontaneous fractures at the site of the tumor, chronic pain
and discomfort, and a continuing chance for spread of cancer cells.
