What is Veterinary Radiation Oncology?
Veterinary Radiation Oncology is a specialized type of cancer treatment that involves radiation therapy to help control internal and external cancerous masses or tumors. Masses or tumors that have been unresponsive to other procedures or that cannot be surgically removed can also respond well to radiation therapy. Radiation therapy is often used in conjunction with surgery, chemotherapy, and other treatment methods.
Radiation Therapy Treatments
Radiation therapy is delivered to the location of the cancerous tumor or mass with a linear accelerator. At Animal Specialty Center, we use a Varian TrueBeam with a sophisticated radiotherapy planning system that enables our veterinary care team to treat a broad range of cancer cases. Our machine is designed with exceptional speed and accuracy, which ensures comprehensive and effective care.
Types of Radiation Therapy
Conventional Radiation Therapy (CRT) / Intensity Modulated Radiation Therapy (IMRT)
Delivers multiple small doses over time for long-term tumor control.
Typically used for mast cell tumors (16 treatments).
Moderate-to-marked temporary side effects expected, peaking a few weeks after treatment.
Stereotactic Radiation Therapy (SRT/SRS/SBRT)
High-dose, highly focused radiation delivered in 1, 3, or 5 sessions.
Requires a CT scan for precise targeting.
Fewer hospital visits and milder side effects compared to CRT.
Palliative Radiation Therapy (PRT)
Medium-dose radiation spaced over time to relieve pain and slow tumor growth.
Often used for oral tumors in pets.
Effects last 3–6 months; repeat treatments may be needed.
Electron Therapy
Used for microscopic disease or surgical scars.
Requires healed surgical sites; sometimes a CT scan is needed.
Usually consists of 15–20 treatments.
