Understanding Vascular Tumors in Cats
When it comes to feline health, it’s important to be aware of potential conditions that can affect our beloved cats. Vascular tumors, though rare, are a type of cancer that can develop in cats. In this section, we will explore what vascular tumors are and the different types that can affect feline companions.
What Are Vascular Tumors?
Vascular tumors are abnormal growths that originate from the blood vessels in the body. These tumors can develop in various parts of the body, including the skin, internal organs, and soft tissues. While vascular tumors can occur in both dogs and cats, they are relatively rare in feline companions, accounting for less than 1.5-2% of non-blood cancers in cats (VCA Hospitals).
Types of Vascular Tumors
There are different types of vascular tumors that can affect cats. Two notable types are hemangiomas and hemangiosarcomas.
Hemangiomas in Cats
Hemangiomas are benign tumors that arise from the blood vessels. These tumors typically appear as small, raised, and reddish growths on the skin. While hemangiomas are generally not life-threatening, they can cause discomfort and may require treatment if they interfere with the cat’s quality of life.
Hemangiosarcoma in Cats
On the other hand, hemangiosarcoma is a malignant tumor that originates from the blood vessel cells. It is considered a rare tumor in cats, accounting for less than 1.5-2% of non-blood cancers in this species (VCA Hospitals). Hemangiosarcomas can develop in various organs, including the skin, liver, spleen, and heart. These tumors are aggressive and can spread to other parts of the body, making early detection and treatment essential.
When it comes to diagnosing vascular tumors in cats, it is important to consult with a veterinarian who can perform a thorough examination and recommend appropriate diagnostic tests. To learn more about diagnosing and treating feline hemangiosarcoma, refer to our article on feline hemangiosarcoma.
Understanding the different types of vascular tumors that can affect cats is crucial for early detection and timely intervention. If you notice any unusual growths or changes in your cat’s behavior, it is important to seek veterinary care. Remember, the earlier these tumors are identified, the better the chances of successful treatment and improved outcomes for our feline companions.
Hemangiomas in Cats
Vascular tumors can affect cats, and one specific type is known as hemangiomas. Let’s explore the characteristics of hemangiomas and the prognosis and treatment options associated with this condition.
Characteristics of Hemangiomas
Hemangiomas in cats are uncommon tumors that typically develop on the head, legs, and abdomen. They resemble blood vessels or “blood blisters” in appearance. These tumors are usually benign, meaning they are non-cancerous, and have an excellent prognosis.
Although hemangiomas are generally benign, they can occasionally rupture, leading to internal bleeding. However, they are not known to spread to other sites in the body.
Surgical removal is typically the treatment of choice for hemangiomas. In cases where the tumors are large or involve the lower legs, freezing (cryotherapy) or radiation therapy may be necessary. However, complete surgical removal usually prevents the tumors from spreading to new locations (Merck Veterinary Manual).
Prognosis and Treatment
The prognosis for cats with hemangiomas is generally favorable due to their benign nature and limited ability to spread. Surgical removal is highly effective in most cases, and it is rare for these tumors to recur after complete excision. If hemangiomas are located in challenging areas or are particularly large, additional treatment options such as freezing (cryotherapy) or radiation therapy may be considered. These interventions aim to eliminate any remaining tumor cells and minimize the risk of recurrence.
Regular follow-up visits with a veterinarian are important after treatment to monitor the cat’s progress and ensure there are no signs of tumor regrowth. Your veterinarian will provide guidance on the appropriate schedule for check-ups based on your cat’s specific situation.
Remember, while hemangiomas are generally benign, it’s essential to consult with a veterinarian for an accurate diagnosis and appropriate treatment plan. Early detection and intervention can lead to successful outcomes for cats with vascular tumors.

Hemangiosarcoma in Cats
Hemangiosarcoma is a type of vascular tumor that affects cats. It is a rare form of cancer, accounting for less than 1.5-2% of non-blood cancers in this species. Hemangiosarcoma in cats has a guarded to poor prognosis, often spreading to other parts of the body and affecting other organs (VCA Canada).
Characteristics of Hemangiosarcoma
Hemangiosarcoma in cats tends to grow large and can regrow even after removal. It is an aggressive tumor that can spread until it blocks surrounding blood vessels or major organs. Despite its aggressive nature, metastasis, or spreading to other parts of the body, is not common in this type of cancer (Wagwalking).
Prognosis and Treatment
The prognosis for cats with hemangiosarcoma is guarded to poor. This type of tumor carries a risk of sudden bleeding, which can be life-threatening. Hemangiosarcoma can also metastasize to other parts of the body, affecting organs such as the lungs, kidneys, muscle, spinal cord, and brain (VCA Hospitals).
Treatment options for hemangiosarcoma in cats vary depending on the extent of the tumor and its location. Surgical removal of the tumor is often the primary treatment approach when feasible. However, due to the aggressive nature of the tumor and the potential for regrowth, additional therapies may be necessary to improve the prognosis. These may include chemotherapy, radiation therapy, or targeted therapies tailored to the individual cat’s condition (VCA Canada).
If you suspect that your cat may have a vascular tumor, it’s important to consult with a veterinarian for a proper diagnosis and treatment plan. Early detection and intervention can significantly impact the outcome and quality of life for cats affected by hemangiosarcoma.

-
Bleeding or Bruising: Vascular tumors, such as hemangiosarcoma, may have a risk of sudden bleeding, leading to bruising or the formation of blood-filled blisters (VCA Hospitals). However, it’s important to note that bleeding is not always present in all cases.
-
Changes in Appetite or Weight Loss: Vascular tumors can sometimes affect a cat’s appetite, leading to a decrease in food intake and subsequent weight loss.
-
Lethargy: Cats with vascular tumors may exhibit signs of lethargy, reduced activity levels, or a lack of interest in their usual daily routines.
It’s important to remember that these symptoms may also be associated with other health conditions. If you observe any concerning signs, it’s best to consult your veterinarian for a proper diagnosis. Early detection and intervention can significantly impact the treatment and management options available for your cat.
In the next sections, we will discuss the causes, risk factors, treatment options, as well as prevention and care strategies for vascular tumors in cats. Stay tuned to learn more about this condition and how to support your feline companion through their journey.
Causes and Risk Factors
When it comes to cat vascular tumors, the exact cause is still unknown. However, it is believed that these tumors develop when pericyte cells, which support a cat’s blood vessels, divide improperly, leading to chromosome damage within the cell (Wagwalking). While the exact triggers remain elusive, there are certain factors that may contribute to the development of these tumors.
Factors Contributing to Development
Although the precise cause of cat vascular tumors is not fully understood, various factors may contribute to their development. These factors can include:
-

-
Environmental Influences: Environmental factors may also contribute to the development of vascular tumors in cats. Exposure to certain carcinogens, such as chemicals or toxins, could potentially increase the risk. However, more studies are required to establish a clear link between environmental factors and the development of these tumors.
Understanding the potential factors that contribute to the development of cat vascular tumors can help veterinarians and cat owners be more vigilant in monitoring their furry companions and seeking early detection and intervention.
Genetic and Environmental Influences
The exact interplay between genetic and environmental influences in the development of cat vascular tumors is a complex subject that requires further investigation. While genetics may predispose certain cats to these tumors, environmental factors can potentially trigger or exacerbate their growth. However, it is essential to note that not all cats with a genetic predisposition will develop vascular tumors, and not all cases can be attributed to specific environmental factors.
As research continues in this field, it is crucial for cat owners to focus on regular veterinary check-ups and be attentive to any symptoms or changes in their cats’ health. Early detection and prompt intervention can make a significant difference in the prognosis and treatment outcomes for cats with vascular tumors.
In the next sections, we will explore the available treatment options and provide guidance on managing vascular tumors in cats.
Treatment Options
When it comes to treating cat vascular tumors, a combination of surgical approaches and additional therapies is typically employed, depending on the type and stage of the tumor. It’s important to work closely with a veterinarian to determine the most appropriate treatment plan for your cat.
Surgical Approaches
Surgery is the recommended treatment for vascular tumors of the skin in cats. For hemangiomas, surgical removal is usually curative, resulting in an excellent prognosis. The procedure involves excising the tumor and a margin of healthy tissue surrounding it to ensure complete removal. This helps to prevent recurrence and minimize the risk of metastasis (VCA Hospitals).
In the case of hemangiosarcomas, surgical removal is also the preferred treatment. However, due to the aggressive nature of these tumors, additional treatment modalities may be necessary. The extent of the surgery will depend on the tumor location, physical exam findings, and staging. In some cases, radiation therapy and chemotherapy may be recommended to target any remaining cancer cells and reduce the risk of recurrence (VCA Hospitals).
Additional Therapies
Depending on the specific circumstances, additional therapies may be utilized alongside or after surgery to enhance the treatment outcomes for cat vascular tumors.
-
Radiation Therapy: Radiation therapy involves the use of high-energy X-rays to target and destroy cancer cells. It may be recommended to address any remaining tumor cells after surgical removal or to treat tumors that cannot be surgically removed. Radiation therapy can help improve local control and reduce the risk of tumor recurrence (Merck Veterinary Manual).
-
Chemotherapy: Chemotherapy may be considered for certain types of cat vascular tumors, particularly in cases where there is a risk of metastasis or if the tumor is not amenable to surgical removal. Chemotherapy involves the administration of medications that target and destroy cancer cells throughout the body. It can help to slow down tumor growth, shrink tumor size, and improve overall survival rates (VCA Canada).
-
Cryosurgery: Cryosurgery, or freezing therapy, can be used for surface tumors. It involves the application of extremely cold temperatures to destroy cancer cells. Cryosurgery may be a viable option for certain types of vascular tumors, particularly those located on the skin surface. It can be used in conjunction with other treatment modalities or as a standalone treatment option for select cases (Merck Veterinary Manual).
The choice of additional therapies will depend on various factors, including the type and stage of the tumor, overall health of the cat, and individualized treatment recommendations from the veterinarian. It’s essential to discuss all available options, potential benefits, and possible side effects with your veterinarian to make informed decisions regarding your cat’s treatment plan.
For the prevention and care of cat vascular tumors, managing and monitoring the skin for any abnormalities is crucial. Regular check-ups with a veterinarian, especially for cats with a higher risk of developing tumors, can help detect and address any potential issues early on. After treatment, post-treatment care, including proper wound management and ongoing monitoring, is vital to ensure the best possible outcome for your feline companion.
Prevention and Care
When it comes to managing vascular tumors in cats, prevention plays a crucial role. While it’s not always possible to prevent the development of these tumors, there are steps you can take to minimize the risk and provide appropriate care for your feline companion. Additionally, post-treatment care is essential to ensure the well-being of your cat.
