Understanding Feline Blood Vessel Cancer
Feline blood vessel cancer encompasses two primary types: hemangiopericytoma and hemangiosarcoma. Understanding these conditions is crucial in recognizing the symptoms and seeking appropriate treatment for affected cats.
Hemangiopericytoma in Cats
Hemangiopericytoma is a relatively rare tumor in cats that arises from pericyte cells, affecting the cells surrounding very small blood vessels in the subcutaneous tissue. This tumor grows continuously at the site of origin and can potentially impair nearby organs, especially when it occurs close to the heart and lungs. Successful treatment is possible, but it is crucial to address the tumor before it grows to unmanageable proportions.
The exact cause of hemangiopericytoma in cats is still unknown. However, there is a possibility of genetic predisposition playing a role in its development.
Hemangiosarcoma in Cats
Hemangiosarcoma is a rare form of tumor seen more frequently in older cats and those with short hair. It is a cancerous condition that originates from blood vessel cells. The underlying disease process is not well understood, making it difficult to identify individual risk factors.
Hemangiosarcoma is an aggressive and fast-moving cancer in cats. Depending on the location of the tumor, the extent of spreading, and the cat’s response to treatment, the veterinarian may be able to extend the cat’s life by up to a year. However, the prognosis can vary significantly, and the overall survival rate is relatively low for cats with this condition (PetCareRx).
Recurrence of hemangiosarcoma is a concern even if successful surgical treatment has been performed. Cats that experience difficulty breathing may indicate a recurrence of the condition, while sudden changes in behavior may be signs of metastasis to the brain. It is crucial to report any new or recurring symptoms promptly to the treating veterinarian for further evaluation and management.
By understanding the different types of blood vessel cancer in cats, such as hemangiopericytoma and hemangiosarcoma, cat owners can be better prepared to recognize potential symptoms and seek appropriate veterinary care. Early detection and timely intervention are key factors in improving outcomes for affected cats.
Causes and Symptoms
When it comes to feline blood vessel cancer, also known as hemangiopericytoma or hemangiosarcoma, the exact causes of these conditions in cats are still not fully understood. However, there are some factors that may play a role in their development.
Causes of Blood Vessel Cancer
The exact cause of cancer of the blood vessels in cats remains unknown. It is believed that these types of cancers occur when pericyte cells, which are cells that surround blood vessels, divide improperly, leading to chromosome damage within the cells. Genetic and environmental factors are thought to contribute to the development of this condition (Wagwalking).
Hemangiopericytoma, a relatively rare tumor in cats, is believed to possibly have a genetic predisposition, although the exact cause is still unknown. Hemangiosarcoma, on the other hand, is a rare form of tumor seen more frequently in older cats and those with short hair. The underlying disease process for hemangiosarcoma is not well understood, making it difficult to identify individual risk factors (Vetster).
Symptoms of Vascular Tumors
The primary symptom of blood vessel cancer in cats is the formation of tumors within the body. These tumors can be fragile and blood-filled. In many cases, symptoms are rarely detected before the tumor bursts, leading to severe internal bleeding (Vetster).
While the symptoms may vary depending on the location and size of the tumor, common signs of blood vessel cancer in cats may include:
- Lethargy and weakness
- Loss of appetite
- Weight loss
- Pale gums
- Difficulty breathing
- Abdominal swelling
- Collapse or sudden onset of weakness
It’s important to note that these symptoms can also be indicative of other health conditions, so it is essential to consult with a veterinarian for a proper diagnosis. Early detection and prompt treatment are crucial for the best possible outcome.
In the next section, we will explore the diagnostic procedures and treatment options available for feline blood vessel cancer.
Diagnosis and Treatment
When it comes to feline blood vessel cancer, early diagnosis and appropriate treatment are crucial for the well-being of your cat. In this section, we will explore the diagnostic procedures used to identify blood vessel cancer in cats and the various treatment options available.
Diagnostic Procedures
To diagnose feline blood vessel cancer, veterinarians employ several diagnostic procedures to assess the presence and extent of the tumor. These may include:
-
Physical Examination: The veterinarian will perform a thorough physical examination of your cat, evaluating any visible signs or symptoms that may indicate the presence of a vascular tumor.
-
Imaging Techniques: Imaging techniques such as X-rays, ultrasound, or CT scans may be used to visualize the tumor and determine its size, location, and potential spread to other areas of the body.
-
Biopsy: A biopsy involves taking a small sample of the tumor tissue for examination under a microscope. This procedure helps confirm the diagnosis and determine the specific type of blood vessel cancer present.
-
Fine Needle Aspiration: In some cases, a fine needle aspiration may be performed to collect a sample of cells from the tumor. This minimally invasive procedure can provide valuable information about the tumor’s composition.
Treatment Options
The choice of treatment for feline blood vessel cancer depends on several factors, including the type of cancer, the extent of the disease, and your cat’s overall health. Common treatment options for feline blood vessel cancer include:
-
Surgical Excision: Early and aggressive surgical removal of the affected tissue, along with some surrounding normal tissue, is often the treatment of choice for blood vessel cancer in cats. This approach aims to remove as much of the tumor as possible.
-
Radiation Therapy: Radiation therapy is a highly effective treatment option for certain types of feline blood vessel cancer, such as hemangiopericytoma. It involves using high-energy radiation to destroy cancer cells and prevent their regrowth. Regular follow-up checkups or additional radiotherapy treatments may be necessary due to the common recurrence of the tumor.
-
Chemotherapy: Chemotherapy may be recommended in cases where the tumor has spread or when surgery alone is not sufficient. It involves the use of medications to destroy cancer cells or inhibit their growth. Chemotherapy is often used in combination with surgery and has been shown to increase survival rates for certain types of blood vessel cancer in cats, such as hemangiosarcoma. Visit our article on feline hemangiosarcoma for more information on chemotherapy treatment protocols.
-
Supportive Care: Supportive care, such as pain management and nutritional support, may be provided to improve your cat’s quality of life during and after treatment.
It’s important to note that the prognosis and survival rates for feline blood vessel cancer can vary depending on several factors, including the nature of the tumor, the aggressiveness of treatment, and the individual response of the cat. Regular follow-up visits with your veterinarian are essential to monitor your cat’s progress and detect any signs of tumor recurrence. For more information on the prognosis of feline blood vessel cancer, refer to our article on cat vascular cell cancer prognosis.
In conclusion, early diagnosis through diagnostic procedures and the appropriate treatment options, such as surgical excision, radiation therapy, and chemotherapy, can significantly improve the outcome for cats with blood vessel cancer. Consult with your veterinarian to determine the best course of action for your cat based on their specific condition and overall health.
Prognosis and Recurrence
When it comes to feline blood vessel cancer, prognosis and the possibility of tumor recurrence are important considerations. Understanding the survival rates and the likelihood of tumor recurrence can help guide treatment decisions and provide insight into the long-term outlook for the affected cat.
Survival Rates
The overall survival time for cats with hemangiopericytoma largely depends on the nature of the tumor and the aggressiveness of surgery and treatment. Animals that undergo early and aggressive surgical resection of the tumor have a chance for a cure, but regular follow-up checkups or radiotherapy treatments are necessary due to the common recurrence of the tumor (PetMD).
For feline hemangiosarcoma (HSA), survival rates vary depending on the treatment approach. Cats treated with surgery alone have a shorter survival time, with most succumbing to cancer spread within approximately 3 months. However, the addition of chemotherapy to treatment protocols has been shown to increase survival. With chemotherapy, survival times generally range from 6-9 months.
Recurrence of Tumors
Unfortunately, hemangiosarcoma is likely to recur even if surgical treatment has been successful. Regular follow-up visits with the veterinarian are crucial to detect and address any signs of recurrence early on. If the cat begins to have difficulty breathing, it may indicate a recurrence of the condition. Sudden changes in behavior may also be a sign that the cancer has metastasized to the brain. Any signs of new or recurring symptoms should be immediately reported to the treating veterinarian.
It’s important to note that prognosis is generally poor for cats with heart hemangiosarcoma. Successful treatment is unlikely to add much time to the cat’s life expectancy. In such cases, treatment recommendations typically focus on minimizing pain and improving the quality of life for the cat’s remaining time.
Regular monitoring and communication with the veterinarian are essential for detecting any signs of tumor recurrence and ensuring appropriate intervention. While the prognosis may be challenging, supportive care and treatment can help maintain the cat’s comfort and quality of life throughout the course of the disease.

Genetic Factors
While the causes of feline blood vessel cancer are multifactorial, genetic factors play a significant role in the development of these tumors. Understanding the genetic basis of feline cancers can provide valuable insights into their etiology and potential treatment options.
Genetic Studies on Feline Cancers
Extensive genetic studies have been conducted to explore the genetic mutations associated with various feline cancers. For example, investigations into feline lymphoma tissue samples revealed mutations in the TP53 gene at codon 282 (exon 8) and codon 199. This mutation is often associated with lymphoma development in cats.
In a study of 150 domestic short-hair cats, a strong association was found between feline injection-site sarcomas (FISS) and specific germ line single nucleotide polymorphisms in the TP53 gene. These findings suggest that certain genetic variations may predispose cats to the development of vascular cell cancers.
Additionally, a study of 13 feline cutaneous hemangiosarcoma cases identified recurrent mutations in genes such as TP53 and NOTCH1. Mutations were also found in ATRX, GLI1, MTOR, PCLO, PGR, PIK3CA, RELN, SETD2, and TERT. These genetic alterations may contribute to the pathogenesis of feline hemangiosarcoma.
Understanding the genetic basis of feline blood vessel cancer is an ongoing area of research, and further studies are needed to fully elucidate the complex interactions between genetic factors and the development of these tumors.
Germ Line Mutations
Germ line mutations refer to genetic alterations that are present in the reproductive cells (sperm or egg) and can be inherited by offspring. These mutations can increase susceptibility to certain diseases, including feline blood vessel cancer.
The presence of specific germ line mutations in the TP53 gene has been associated with the development of feline injection-site sarcomas. These findings highlight the role of inherited genetic variations in the predisposition to certain types of vascular cell cancers in cats.
It is important to note that while genetic factors may contribute to the development of feline blood vessel cancer, they do not guarantee the development of the disease. Environmental factors and other variables also play a role in tumor formation and progression.
By studying genetic factors associated with feline blood vessel cancer, researchers can gain insights into the underlying mechanisms of these tumors. This knowledge may eventually lead to more targeted treatment options and improved prognoses for affected cats.

Feline Hemangiosarcoma
Feline hemangiosarcoma is a rare form of cancer that originates from the blood vessel cells in cats. It is more commonly seen in older cats and those with short hair, although the underlying disease process is not well understood, making it difficult to identify individual risk factors.
Characteristics and Locations
Hemangiosarcoma in cats has the potential to affect various tissues in the body, with common primary sites being the spleen/internal organs, skin, or subcutaneous tissue. Cutaneous hemangiosarcoma tends to have a lower metastatic rate, while deeper tumors have a greater likelihood of metastasis.
The primary symptom of feline hemangiosarcoma is the formation of fragile, blood-filled tumors within the body. However, these tumors are rarely detected before they burst, leading to severe internal bleeding. Due to the aggressive nature of the cancer, early detection is challenging, and diagnosis often occurs after a tumor rupture has already occurred (Vetster).
Treatment Protocols
The prognosis for cats with visceral hemangiosarcoma is generally poor. Treatment options focus on stabilizing the patient, surgically removing the tumor or affected organ, and potentially using chemotherapy to reduce the spread and recurrence of the cancer. However, it is important to note that feline hemangiosarcoma is highly metastatic and is typically diagnosed after a tumor rupture, which poses significant challenges for successful treatment (Vetster).
Surgery to remove the primary tumor is an important part of the treatment protocol for feline hemangiosarcoma. While surgery alone can be curative for superficial skin-associated hemangiosarcoma, it is not as effective for deeper tumors. In cases where the cancer has spread or metastasized, the addition of chemotherapy to the treatment plan has been shown to increase survival rates. Most cats undergoing treatment for hemangiosarcoma can maintain an excellent quality of life (Livs.org).
To determine the best course of action for treating feline hemangiosarcoma, it is essential to consult with a veterinarian who can assess the specific circumstances of the cat and recommend an appropriate treatment plan. The cost of treatment may vary depending on the extent of the disease and the chosen treatment options. For more information on the prognosis and treatment options for feline hemangiosarcoma, please refer to our article on cat vascular cell carcinoma.
By understanding the characteristics of feline hemangiosarcoma and the available treatment protocols, cat owners can work closely with their veterinarians to provide the best possible care for their feline companions. Regular check-ups and preventive measures can also play a crucial role in the early detection and management of this aggressive form of cancer.
