Overview
Osteosarcoma is a malignant bone tumor that is most commonly diagnosed in dogs, but it can also occur in cats. This aggressive cancer predominantly affects the long bones and can lead to severe complications if not treated promptly.
Causes
The exact cause of osteosarcoma is not fully understood, but genetic factors, previous fractures, and exposure to radiation may play a role in its development.
Symptoms & Signs

- Mild pain in the affected limb
Advanced Symptoms
- Swelling at the tumor site
- Severe pain
Emergency Symptoms
- Sudden, unexplained fracture
- Extreme discomfort or distress
Diagnosis
Diagnosis typically involves a combination of physical exams, X-rays, and biopsies to confirm the presence of cancerous cells in the bone.
Treatment Options
Home Care
- Providing a comfortable resting area

Prevention
While there is no sure way to prevent osteosarcoma, maintaining a healthy lifestyle and regular veterinary check-ups can help in early detection.
Prognosis & Recovery
The prognosis for osteosarcoma varies depending on the stage at diagnosis and the treatment plan. Early intervention can improve the outcome.
