Brain Tumor in Cats and Dogs

Brain tumors are relatively common in older dogs and cats. Some tumors are "primary" brain tumors, meaning that they originate from the tissue in the brain cavity, and some are "secondary" brain tumors, or those that originate from outside the brain cavity but then invade the brain by extension (for example, from the nose) or via the blood (metastasis). Most brain tumors are diagnosed in dogs and cats older than 5 years and mainly in pets 9 years of age and older. Younger animals, though, can also be affected.
