What is it? Cancer affecting the brain is common in older dogs and cats and can rarely be seen in younger animals. Tumors can arise primarily from the brain or can be caused by spread of tumors located elsewhere in the body. The most common form of primary brain tumors in dogs and cats are known as meningiomas, originating from the membrane that covers the brain (meninges). This tumor type is usually slowgrowing and amenable to treatment. Other types of tumors include gliomas, choroid plexus adenomas, pituitary adenomas or adenocarcinomas, and others. Most animals present to their veterinarian for seizures or behavioral changes, such as loss of learned behavior or depression. Diagnosis is determined by a complete physical, neurological examination, and/or advanced imaging (MRI or CT).
How is it treated? The options for treating brain tumors include surgical removal, radiation therapy, chemotherapy, and palliative treatment of the symptoms.
What is the prognosis for a brain tumor? It is important to note that most brain tumors are treatable, but not curable. The mean survival time for pets with untreated brain tumors is relatively short. Dogs have an excellent prognosis following complete excision of solitary cerebral meningiomas. Radiation therapy is associated with a better prognosis than surgery alone or conservative management. Brain tumors that are not treated or that are aggressive will result in progressive disease. A personalized treatment plan is important to slow the progression of cancer. Talk to your veterinarian regarding the best treatment protocol for your pet.
