Pets develop a variety of bone tumours but the most common is the highly malignant osteosarcoma. These are most likely to occur in the long bones of middle-aged or older large and giant dog breeds.
Diagnosis asnd treatment
Diagnosis is confirmed by x-ray. Unfortunately, by the time a primary osteosarcoma has been discovered there is a 90 percent chance it has spread to other parts of the body, the lungs and liver in particular. This affects decisions about possible treatments. Amputation remains the treatment of choice for primary tumours in long bones. Alternative limb-sparing techniques may also be used to control tumour-associated pain. Radiation therapy carried out at Cambridge University can be very effective to relieve pain. With dramatic intervention about one half of affected pets survive a year or more.
