Understanding Brain Tumors in Cats
When it comes to feline health conditions, the presence of brain tumors can be a cause for concern. Understanding the basics of brain tumors in cats is essential for early detection and appropriate management.
Overview of Brain Tumors
Brain tumors in cats refer to the abnormal growth of cells within the brain. These tumors can originate from various parts of the brain, including the meninges, which are the protective coverings of the brain. The most common type of brain tumor in cats is a benign tumor called a meningioma. Other types of brain tumors seen in cats include gliomas, lymphosarcoma (lymphoma), choroid plexus papillomas, and pituitary tumors (PetMD).
It’s important to note that these tumors can vary in their location, size, and aggressiveness. The symptoms and prognosis can differ depending on the specific type and characteristics of the tumor.
Common Types of Brain Tumors
-
Meningioma: Meningiomas are the most common type of brain tumor in cats. These tumors arise from the meninges, which are the protective coverings of the brain. Meningiomas are usually benign (non-cancerous) and tend to grow slowly. However, they can still cause significant neurological symptoms due to their location and size. The mean survival time for untreated meningioma is approximately 18 days.
-
Glioma: Gliomas are another type of brain tumor that can affect cats. These tumors originate from the supporting cells in the brain called glial cells. Gliomas can be either benign or malignant (cancerous). Malignant gliomas tend to be more aggressive and can rapidly spread to surrounding brain tissues.
-
Lymphoma: Lymphoma, also known as lymphosarcoma, is a cancerous tumor that can affect various parts of the body, including the brain. In cats, lymphoma can manifest as a primary brain tumor. Lymphoma tumors originate from the lymphocytes, a type of white blood cell.
-
Choroid Plexus Papilloma: Choroid plexus papillomas are rare brain tumors that arise from the choroid plexus, which is responsible for producing cerebrospinal fluid. These tumors are usually benign and slow-growing.
-
Pituitary Tumors: Pituitary tumors can also occur in cats. These tumors originate from the pituitary gland, which is responsible for producing various hormones. Pituitary tumors can cause hormonal imbalances and neurological symptoms.
Understanding the common types of brain tumors in cats is crucial for early recognition of potential symptoms and prompt veterinary intervention. If you suspect that your cat may be exhibiting signs of a brain tumor, such as changes in behavior, seizures, or coordination difficulties, it’s important to seek veterinary care for a proper diagnosis and appropriate treatment.
Causes and Risk Factors
When it comes to brain tumors in cats, several factors can contribute to their development. Understanding these causes and risk factors can help shed light on the occurrence of these tumors in our feline companions.
Age and Incidence
Cats over 10 years of age are more likely to develop brain tumors compared to younger cats. As cats age, their risk for various health conditions, including brain tumors, increases. It is important for cat owners to be aware of this correlation and monitor their senior cats for any potential signs or symptoms of a brain tumor.

Breed Predispositions
While brain tumors can affect cats of any breed, certain breeds may have a higher incidence of specific types of brain tumors. For example, one study showed an increase in meningiomas in domestic short-haired cats, while another study found a higher incidence of meningiomas in Siamese cats. Additionally, some researchers have observed a higher incidence of meningiomas in male cats. However, further studies are needed to confirm these results and establish stronger breed predispositions.
It’s important to note that primary brain tumors in cats can include meningioma, glioma, choroid plexus papilloma, pituitary adenoma or adenocarcinoma, and others. Meningioma, arising from the arachnoid mater of the meninges, is the most common primary brain tumor in cats. However, these tumors occur more commonly in long-nosed breeds of dogs such as the Golden Retriever (NC State Veterinary Hospital).
In addition to primary brain tumors, secondary brain tumors can also occur. These tumors represent the spread of cancer from another part of the body to the brain. Examples of tumors that may spread to the brain include hemangiosarcoma, mammary carcinoma, and melanoma. Unfortunately, secondary brain tumors carry a poor prognosis as they have already spread through the body.
By understanding the causes and risk factors associated with brain tumors in cats, pet owners can be more vigilant in monitoring their cats’ health, especially as they age. Regular veterinary check-ups and timely diagnostic imaging techniques, such as magnetic resonance imaging (MRI) or computed tomographic (CT) scans, can aid in the early detection and diagnosis of brain tumors in cats (NC State Veterinary Hospital).
Symptoms and Diagnosis
Identifying the presence of a brain tumor in cats can be challenging, as the symptoms can vary depending on the location and size of the tumor. However, understanding the neurological signs associated with brain tumors and utilizing diagnostic imaging techniques can aid in the diagnosis process.
Neurological Signs
Brain tumors in cats can cause signs by compressing or invading different areas of the brain. The resulting signs are not specific to a tumor but relate directly to the affected area of the brain. These signs may appear suddenly or develop gradually, and their severity can vary.
Some common neurological signs associated with brain tumors in cats include:
- Changes in behavior
- Loss of balance
- Weakness on one side of the body
- Difficulty swallowing
- Coordination issues
The forebrain, brainstem, and cerebellum are areas of the brain that can be affected by tumors, leading to these various symptoms. Keep in mind that any disease affecting these areas of the brain could produce similar signs, so it’s important to consult a veterinarian for an accurate diagnosis.

Diagnostic Imaging Techniques
When a brain tumor is suspected in cats, diagnostic imaging techniques are essential for confirming the presence and location of the tumor. Radiographs of the skull are not sufficient for visualizing brain tumors, so magnetic resonance imaging (MRI) or computed tomographic (CT) scans are recommended.
MRI is often the preferred imaging modality, as it provides detailed images of the brain and allows for better visualization of soft tissues. It can help identify the size, extent, and location of the tumor. CT scans may also be utilized, particularly for cases where MRI is not feasible or available.
By utilizing these diagnostic imaging techniques, veterinarians can obtain valuable information about the brain tumor, aiding in the development of an appropriate treatment plan. In some cases, a biopsy may be necessary to determine the type of tumor and guide treatment decisions.

Understanding the neurological signs associated with brain tumors and utilizing diagnostic imaging techniques are crucial steps in diagnosing brain tumors in cats. If you suspect that your cat may have a brain tumor based on observed symptoms, it is important to consult with a veterinarian for a thorough examination and appropriate diagnostic tests. Early detection and diagnosis can help guide treatment decisions and improve the overall prognosis for your feline companion.
Treatment Options
When it comes to treating brain tumors in cats, there are several options available depending on the specific situation and the type of tumor. The two primary treatment options for brain tumors in cats are surgical removal and chemotherapy and radiation therapy.
Surgical Removal
Surgery is often considered the ideal treatment for cats with brain tumors, especially if the tumor can be fully removed. However, it is important to consult with your veterinarian to discuss the risks associated with surgery and the likelihood of completely removing all cancer cells (PetCure Oncology). In some cases, the location of the tumor may make complete removal impossible.
During surgery, the veterinarian will aim to remove as much of the tumor as possible without causing damage to surrounding healthy brain tissue. The extent of the surgery will depend on the size and location of the tumor. Post-operative care and monitoring are crucial to ensure proper healing and to address any potential complications.
Chemotherapy and Radiation Therapy
In cases where complete surgical removal is not feasible, or in situations where the tumor has spread beyond the surgical site, chemotherapy and radiation therapy may be recommended. Chemotherapy is a common cancer treatment that involves using drugs to target cancer cells throughout the body. It is typically used to treat systemic cancers or tumors that have spread (PetCure Oncology).
Radiation therapy, on the other hand, focuses on using high-energy beams to target and destroy cancer cells. It can be particularly useful for tumors that are difficult to access surgically. Radiation therapy may be administered externally or internally, depending on the specific needs of the cat.
It’s important to note that the cost of treatment for brain tumors in cats can vary significantly. Surgery typically ranges from $4,000 to $7,000, while chemotherapy ranges from $2,000 to $4,000, and radiation from $6,000 to $9,000 (PetMD). However, it’s crucial to discuss the costs and potential outcomes with your veterinarian to make an informed decision about the best course of treatment for your cat.
The treatment approach for brain tumors in cats depends on various factors, including the type and location of the tumor, as well as the overall health and age of the cat. It’s essential to work closely with your veterinarian to determine the most appropriate treatment plan tailored to your cat’s specific needs. Regular follow-up visits and ongoing monitoring are crucial to evaluate the response to treatment and make any necessary adjustments to ensure the best possible outcome for your feline companion.
Prognosis and Survival Rates
When it comes to brain tumors in cats, the prognosis and survival rates can vary depending on several factors. It’s important to understand these factors to have a realistic expectation of the outcome for your feline companion.
Median Survival Time
The median survival time for cats with brain tumors can vary depending on the type of tumor and the chosen treatment options. For example, meningiomas, a type of brain tumor in cats, have a mean survival time of 18 days if left untreated. However, with appropriate treatment, the survival time can be prolonged. Advanced radiation therapy for gliomas has a median survival time ranging from 12 to 14 months, while meningiomas can have a median survival time of 20 to 24 months, depending on the type of cancer and the timing of treatment (PetCure Oncology).
It’s important to note that these are median survival times, meaning that some cats may survive longer, while others may have a shorter survival time. Individual cases may vary, and it’s crucial to consult with a veterinarian who can provide personalized guidance and treatment options based on your cat’s specific condition.
Factors Affecting Prognosis
Several factors can influence the prognosis of a cat with a brain tumor. These factors include:
-
