Why brain tumors in pets
are different — and treatable.

Brain tumors are among the most challenging diagnoses in veterinary oncology — but also among the most responsive to radiation therapy. For many dogs and cats, radiation therapy is not a last resort. It is the primary treatment.

The most common brain tumors in dogs and cats — meningiomas, gliomas, and choroid plexus tumors — originate in or adjacent to the brain and grow slowly at first. Because the skull contains the tumor within a fixed space, even gradual growth produces neurological symptoms that tend to appear suddenly and worsen quickly.

Why surgery alone is rarely enough

Unlike tumors in other parts of the body, brain tumors cannot always be safely removed in their entirety. The brain's complex anatomy means that aggressive surgical resection carries serious risk of permanent neurological damage. In many cases, surgery can relieve pressure and provide a tissue diagnosis, but it cannot eliminate the tumor completely.

This is where radiation therapy becomes essential. Radiation targets the tumor volume precisely, destroying cancer cells while sparing the surrounding healthy brain tissue — a balance that surgery alone cannot always achieve.

When symptoms appear — what to expect

Neurological symptoms — seizures, circling, head tilt, behavioral changes, loss of coordination, vision changes — can escalate quickly once they begin. Early evaluation by a specialist is important: the sooner radiation begins, the less neurological compromise has occurred, and the better the response typically is.
