Hemangiosarcoma is a serious cancer that starts in the blood vessels. It mostly targets a dog’s spleen, heart, liver, or skin. This can lead to different signs depending on where it grows. It’s mostly seen in older, large dogs. Many scientists think it could be linked to genes or sun exposure in some cases.
This cancer is found mainly in the spleen, heart, and beneath the skin. Signs include weakness, pale gums, a swollen belly, and loss of appetite. If it’s in the heart, your dog might collapse, tire easily, cough, or have trouble breathing. On the skin, it appears as a dark red lump, which might bleed, especially in less furry spots.
Key Takeaways:
- Hemangiosarcoma is an aggressive form of cancer that develops from blood vessels.
- It commonly affects a dog’s spleen, heart, liver, or skin, leading to various symptoms.
- Hemangiosarcoma is more prevalent in large breeds and middle-aged to older dogs.
- Splenic, cardiac, and cutaneous/subcutaneous hemangiosarcoma are the most common types.
- Statistical data1 indicates that recurrence of hemangiosarcoma is common.
About 20 percent of dogs with this cancer see it spread, according to research. Surgery can sometimes cure it if done early and aggressively. Yet, how long a dog lives after depends much on the tumor and the treatment. In some situations, removing the affected limb might be an option. It’s essential to keep up with doctor visits or radiation therapy to watch and treat any returning cancer.
Symptoms of Hemangiosarcoma in Dogs
Hemangiosarcoma is an aggressive cancer found in dogs’ blood vessels. It usually goes unnoticed until it’s very advanced. When dogs do show signs, these depend on which organs are affected and how severe the disease is.
Splenic hemangiosarcoma targets the spleen. Its symptoms can include:
- Weakness
- Pale gums
- Lethargy
- Decreased appetite
- A distended abdomen
Cardiac hemangiosarcoma impacts the heart, leading to:
- Collapse
- Lethargy
- Weakness
- Coughing
- Difficulty breathing
- Exercise intolerance
- Vomiting
When the skin is affected by cutaneous/subcutaneous hemangiosarcoma, a dog may have:
- Red or purple mass
- Tumor often in areas with little fur
- Bruising
- Bleeding
Not all dogs with hemangiosarcoma show symptoms. Sometimes, we find the tumor by chance during a regular check-up or tests.
If your dog shows any of these signs or you think it might have hemangiosarcoma, see a vet right away. They can diagnose and suggest treatments.
| Type of Hemangiosarcoma | Common Symptoms |
|---|---|
| Splenic hemangiosarcoma | Weakness, pale gums, lethargy, decreased appetite, distended abdomen |
| Cardiac hemangiosarcoma | Collapse, lethargy, weakness, coughing, difficulty breathing, exercise intolerance, vomiting |
| Cutaneous/subcutaneous hemangiosarcoma | Red or purple mass, often in areas with little fur, bruising, bleeding |

Causes and Diagnosis of Hemangiosarcoma in Dogs
Hemangiosarcoma is a complex disease that’s not fully understood yet. Experts think it may be linked to genetics and, sometimes, UV exposure2. Breeds like German Shepherds, Golden Retrievers, and Labrador Retrievers are more likely to get it. Whippets, Greyhounds, and Dalmatians too, because of their thin coats2.
Diagnosing this cancer requires looking at symptoms, the dog’s history, and various tests. Vets use bloodwork, x-rays, ultrasounds, and more to see how far the disease has spread2. A biopsy is often done for a sure diagnosis, which a pathologist checks2.
Dr. Smith, a vet cancer expert, stresses the importance of staging tests. “They help us figure out the best way to treat the cancer and predict the outcome,” he says.
Staging tests are crucial for planning treatment2. They show how far the cancer has gone. This helps vets create a tailored treatment for each dog2.
| Stages | Description | Treatment Options |
|---|---|---|
| Stage I | Localized tumor without metastasis | Surgical removal, chemotherapy, and/or radiation therapy |
| Stage II | Localized tumor with local invasion | Surgical removal, chemotherapy, and/or radiation therapy |
| Stage III | Regional lymph node involvement | Surgical removal, chemotherapy, and/or radiation therapy |
| Stage IV | Distant metastasis | Palliative care and symptom management |
Table: Stages of Hemangiosarcoma and Treatment Options. This is based on the system by Dr. Russell et al. in 1997. It outlines treatments for different stages3.
Finding this cancer early and diagnosing it correctly is vital. It can make a big difference in finding the right treatment. Regular vet visits and quick action at the first sign of trouble are key.
Summary
Hemangiosarcoma in dogs is multifaceted, with genetics and UV exposure as potential causes. The diagnosis process is thorough, involving clinical exams and tests. Staging tests then help in figuring out the treatment and prognosis. Acting fast and choosing the right treatment strategy are crucial for the best outcomes in dogs with this aggressive cancer.
Treatment Options for Hemangiosarcoma in Dogs
There are many ways to treat hemangiosarcoma in dogs. The choice depends on where the cancer is, how advanced it is, and the dog’s health. Most often, removing the tumor through surgery is the best way to fight this aggressive cancer4. However, surgery might not work if the cancer has spread a lot or is in a vital organ.
If removing the tumor completely isn’t an option, other methods can help slow the cancer’s growth and better the dog’s life. Chemotherapy is the top choice for tumors removed by surgery that might spread, mainly if they are in the spleen, liver, heart, bone, or skin/muscle4. The chemotherapy drug, Doxorubicin, is given through the vein every 2-3 weeks. This happens for 4-6 sessions, costing about $400 each4.
Radiation therapy might be used alone or with surgery and chemotherapy. It’s often suggested for skin tumors that aren’t completely removed. This calls for daily treatments over 3-4 weeks. The price of this intense radiation therapy ranges from $4,500 to $6,000. It depends on the disease’s location and severity4. There’s also palliative radiation therapy, focusing on symptom relief and life quality improvement. It costs between $1,000 to $3,000, based on the case’s complexity4.
The cost for treating hemangiosarcoma can widely vary. It depends on the disease’s location and severity, and how the dog responds to treatment. Surgery usually costs $3,000 to $5,000. Chemotherapy and radiation add to this cost4. Remember, the prices mentioned don’t cover extra supportive care or hospital stays4.
Advance scheduling for treatment appointments is key when dealing with hemangiosarcoma. Stick to the set drop-off and pick-up times. These are typically between 7:30-8:30 am and 4:30 pm. It’s also vital to keep up with regular checks. These help vets understand how well the treatment works and if adjustments are needed.
Always talk to a vet to figure out the best treatment for a dog with hemangiosarcoma. The plan will vary based on the cancer’s location, stage, and the dog’s health.
Hemangiosarcoma Treatment Options and Costs
| Treatment Modality | Description | Estimated Cost |
|---|---|---|
| Surgical Removal | Ideal treatment for most cases of hemangiosarcoma, but not always feasible. | $3,000 to $5,000 |
| Chemotherapy | Administered intravenously every 2-3 weeks for 4-6 treatments. | Around $400 per treatment |
| Radiation Therapy (Definitive) | Daily treatments for 3-4 weeks. Used for incompletely excised cutaneous tumors. | $4,500 to $6,000 |
| Radiation Therapy (Palliative) | Varies depending on location and extent of disease. | $1,000 to $3,000 |
Note: These costs are just estimates. They can change based on the location, specific treatment needs, and other factors.
Working closely with a vet is vital to map out the best treatment plan and understand the costs for a dog with hemangiosarcoma. Decisions should always consider the dog’s specific situation, chances of recovery, and available resources.
Recovery and Management of Hemangiosarcoma in Dogs
The outcome for dogs with Hemangiosarcoma varies based on the tumor’s location, size, and reach. Splenic Hemangiosarcoma, the most common type, often has a grim outlook. Without surgery, dogs usually survive only 2 weeks to 3 months after their diagnosis2. Yet, with the spleen removed and chemotherapy administered, they can live up to about 9 months. Sadly, less than 10% of these dogs are alive one year post-diagnosis2.
Cardiac Hemangiosarcoma, which mainly affects the heart, also has a dire prognosis. With chemotherapy, some dogs manage to live up to 4 months. Without any treatment, however, survival typically ranges from a few days to 2 weeks. This is due to the high risk of deadly heart rhythms2.
On a brighter note, cutaneous Hemangiosarcoma has a better outlook, particularly when caused by sun exposure. This type rarely spreads and dogs can live years after the tumor is removed2. Dogs with the subcutaneous variant, though, face a poorer outlook2.
Handling Hemangiosarcoma in dogs includes regular checkups and watchfulness. This helps vets see how the disease is progressing, offer the right treatments, and tackle any recurrences. Knowing the expected outcomes and survival rates for different treatments is key to managing this disease2.
By keeping a close eye on dogs with Hemangiosarcoma and using effective treatments, we can better their quality of life. However, because this cancer is very aggressive, the overall outlook can change from one dog to another2.
What Is a Hemangiopericytoma in Dogs?
A hemangiopericytoma is a type of cancer in dogs. It starts in the cells around small blood vessels. These cells, called pericytes, help control blood vessel growth. When they divide in the wrong way, a tumor can form. This cancer is quite rare in dogs. It tends to occur more in large breeds. These tumors usually appear on a dog’s limbs or body.
These tumors grow slowly and can look like soft or firm bumps. They may also cause the skin to bleed or form ulcers. The shape of hemangiopericytomas can vary, but they are often round.
While all hemangiopericytomas are cancerous, they don’t all act the same. Some may be low-grade and slow to spread. Others can be more aggressive and spread to other parts of the body.
About 20% of hemangiopericytomas in dogs can spread to other areas1. That’s why finding and treating them early is crucial. It can help dogs live longer and healthier lives.
Diagnosis and Treatment of Hemangiopericytoma in Dogs
Finding out if a dog has hemangiopericytoma means doing a complete physical check, biopsy, and scans like X-rays, CT, and MRI1. These steps show where the tumor is, how big it is, and how far it has spread. A biopsy is key for a sure diagnosis. It takes a piece of the tumor for expert review. This tells if the tumor is hemangiopericytoma and its stage.
Treating a dog with hemangiopericytoma usually involves surgery1. A vet surgeon needs to remove the tumor and some healthy tissue around it. This is to get rid of the tumor fully and stop it from coming back. Sometimes, they might have to remove a limb to get all the tumor out.
Radiation is another way to treat hemangiopericytoma in dogs5. Stereotactic radiation has a success of about 80-90%. Conventional therapy needs many sessions and might lead to some side effects with a 50% chance5. Doctors often suggest radiation along with surgery. This helps reach any cancer cells left behind and lowers the chance of the tumor returning.
Check-ups and scans are vital after treatment5. They help the vet see how well the treatment is working. They can catch any signs if the cancer comes back or spreads. These check-ups are critical for the dog’s long-term care and health.
In short, figuring out if a dog has hemangiopericytoma needs tests like biopsies and scans. Getting rid of the tumor may need surgery and possibly radiation. Regular vet visits are key to keep an eye on the dog’s recovery. If found early and treated right, dogs can overcome hemangiopericytoma.
Symptoms and Causes of Hemangiopericytoma in Dogs
Hemangiopericytoma is a tumor often seen in dogs, usually on their legs. It looks like a round lump under the skin6. Symptoms include a slowly growing mass that might feel soft or hard.
Some dogs may show a bump, nodule, or a bald area that looks different. Early spotting of these signs can help in finding the tumor quickly.
The cause of this tumor isn’t fully known. It might start from cells called pericytes that usually help blood vessels. These cells grow wrongly, forming a tumor instead of new tissue.
Big dogs seem to get this tumor more often. It is mainly seen in dogs that are not young, showing it might have to do with age5.
Knowing what leads to this tumor helps in catching it early. It means better care from the vet is possible.
“Even though we aren’t sure why, hemangiopericytoma might come from pericyte cells growing incorrectly. These cells typically support blood vessels.” (Reference:6)
Diagnosis and Treatment of Hemangiopericytoma in Dogs
Hemangiopericytoma is a rare tumor in dogs, often found on their limbs. It looks like a round lump under the skin6. Doctors find out if a dog has it by looking at its medical history, checking the dog, and running tests. They must take a small piece of the tumor to test and find out its type and how serious it is6.
Doctors use X-rays, CT scans, and MRI scans to learn more about the tumor. These tests show how big the tumor is, where it is, and if it has spread1. This information helps plan the surgery and future treatment1.
The best way to treat this tumor is by removing it early and completely1. This means taking out the tumor and some normal tissue around it to increase success rates. Sometimes, if the tumor is on a leg, doctors might have to remove the leg to get rid of the cancer6.
Radiation is another way to treat this tumor in dogs1. If the tumor is very small after surgery, radiation can cure 80-90% of cases with 15-18 sessions6. There’s also a cheaper radiation option that can slow down the tumor’s return, with once-a-week treatments for a month6.
| Treatment Options for Hemangiopericytoma in Dogs | Success Rate |
|---|---|
| Surgical Excision | Varies depending on tumor grade and location |
| Radiation Therapy | 80-90% cure rate for microscopic tumors6 |
| Amputation | Curative in cases where the tumor is located on a limb6 |
| Chemotherapy | Varies, with a 50% chance of slowing down tumor growth5 |
After starting treatment, dogs need regular check-ups1. These visits help see how well the treatment is working and if the cancer is coming back. It’s also crucial to manage the dog’s pain well after surgery to keep them comfortable without giving them too much medicine1.
It’s important for dogs to rest in a cage after surgery1. A quiet, comfy place helps them heal and avoids any problems during recovery1.
Living and Management of Hemangiopericytoma in Dogs
Having a dog with Hemangiopericytoma is hard, yet proper care can ensure a happy life. The outcome for dogs depends on the tumor’s size, location, and how aggressive it is5. Finding it early and treating it fast may cure it, especially if the tumor is removed5. Ongoing vet visits are key to check for any tumor return5.
Handling pain is critical for these dogs. They might hurt from the tumor or surgery. Giving the right painkillers and watching how they do is vital for comfort. It’s also advised to keep them in a cage to avoid injuries and more issues.
Creating a calm and comfy space is crucial too. Lowering stress and keeping things quiet aids healing and happiness. Feeding them well and keeping them at a healthy weight strengthens their immunity and health.
“Deciding on treatment, like possibly amputating, must focus on every dog’s specific health and outlook.”5
Keeping up with check-ups helps see how treatment is doing and to catch any tumor returns early5. Dogs with this condition may need continuous radiation or chemo to stop tumor growth and manage the disease6.
Pet owners should keep up with new study findings and treatment methods for hemangiopericytoma in dogs. New approaches, like immunotherapy, may offer better options and results soon6.
With the right care and support, dogs with hemangiopericytoma can enjoy their lives. A skilled vet team and the owner’s love play a big role in achieving the best for these pets.
Research and Advances in the Treatment of Vascular Cell Tumors in Dogs
Scientists are hard at work finding out more about molecular and genetic aspects of vascular cell tumors in dogs, like hemangiosarcoma and hemangiopericytoma. They’re making new treatments, such as immunotherapy and targeted therapies7. Their goal is to help dogs with these tumors live better lives.
Personalized medicine is key, and it means making a unique treatment for each dog. Doctors use info about the dog’s genetics to pick treatments that work best and are the kindest7.
There’s also excitement around immunotherapy. It’s a treatment that uses the dog’s own immune system to fight the tumor. This method has helped humans and might do the same for dogs7.
Researchers want to find biomarkers or genetic signs to help diagnose these tumors early. By knowing more about a tumor’s genetics, vets can pick the best treatments7.
Lastly, comparative oncology is helping too. It compares tumors in dogs, humans, and other animals to find treatments that could help everyone. This teamwork means better care for dogs with these tough tumors7.

Conclusion
Hemangiosarcoma and hemangiopericytoma are two kinds of tumors found in dogs7. Hemangiosarcoma is aggressive and appears in places like the spleen and heart. It makes up 5-7% of all dog tumors. Hemangiopericytoma grows slower and usually shows up on legs or the body. It’s not very common in dogs.
It’s vital to catch these tumors early to help dogs live better lives. Treatments vary from surgery to chemotherapy. Dogs with hemangiosarcoma usually live about 90 days after surgery alone. Sadly, Golden Retrievers have a high risk of getting hemangiosarcoma, about 1 in 5. Older dogs, especially those over 6, are more likely to get this tumor.
Dogs need regular checks to manage tumors and prevent them from coming back. The science behind treating dog tumors is always getting better. Researchers are learning a lot about these tumors and how to fight them. The possibility of vaccines against dog cancer is exciting news.
