What is an important distinguishing feature of osteosarcoma in cats compared to dogs?

Osteosarcoma in cats is indeed characterized by being less aggressive compared to dogs. This distinction is noted in the clinical behavior and progression of the disease. In cats, osteosarcoma tends to have a slower growth rate and a lower likelihood of metastasis at the time of initial diagnosis, which often makes the overall prognosis somewhat better than in dogs.

This difference in aggressiveness can influence treatment approaches and outcomes in feline patients. While both species can develop this type of bone cancer, the clinical presentation and biological behavior vary significantly. In dogs, for instance, metastasis often occurs earlier and more aggressively, leading to a generally poorer prognosis. Understanding this key distinction is crucial for veterinarians when assessing and treating potential cases of osteosarcoma in small animals.
