Hemangiosarcoma in Dogs: Symptoms, Diagnosis, and Treatment Understanding Hemangiosarcoma in Dogs

Hemangiosarcoma is a type of cancer that affects the blood vessels and is often found in dogs. It is a very malignant and aggressive kind of cancer that, if ignored, can spread quickly to other regions of the body. Despite its prevalence and severity, many pet owners are unfamiliar with the symptoms and treatment options for this disease. 

In this article, we will provide an overview of hemangiosarcoma in dogs, including its causes, symptoms, and available treatment options.

Causes

Although the precise cause of canine hemangiosarcoma is unknown, various risk factors have been noted. These include:

• Age: Hemangiosarcoma is more commonly found in older dogs, typically those over six years of age.

• Breed: The prevalence of this condition is higher in several breeds, including German Shepherds, Golden Retrievers, and Labrador Retrievers.

• Gender: Male dogs are more prone to hemangiosarcoma development.

• Sun exposure: Dogs with white or light-colored skin that is oftentimes exposed to the sun may have a higher risk of developing hemangiosarcoma.

• Chronic inflammation: Dogs with a history of long-term inflammation or previous trauma to the affected area may have a hiked risk of developing hemangiosarcoma.

Symptoms

As the cancer is frequently internal and can spread quickly to other parts of the body, the early symptoms of canine hemangiosarcoma can be challenging to identify. Some typical signs include:

• Weakness and lethargy

• Loss of appetite

• Rapid breathing or panting

• Abdominal swelling or a distended belly

• Sudden weakness

• Pale gums and mucous membranes

• Rapid heartbeat

• Breathing difficulties

• Bruising or unexplained bleeding

However, these symptoms may be caused by other health issues, so a definitive diagnosis can only be made through veterinary examination and testing.

Diagnosis

• Physical examination: Your dog will have a comprehensive physical check by the vet, who will also record any strange signs, lumps, or bumps.

• Blood tests: Blood tests can help diagnose hemangiosarcoma by checking for anemia, elevated liver enzymes, and clotting disorders.

• Imaging tests: X-rays, ultrasounds, and CT scans are imaging techniques that can be used to detect tumors and assess the severity of the disease.

• Biopsy: Hemangiosarcoma generally requires a biopsy to confirm the diagnosis. The damaged tissue can be surgically removed for the biopsy, or it can be done with a needle.

Treatment and Management Options

Treatment options for hemangiosarcoma in dogs may include:

• Surgery: The most regular form of treatment for hemangiosarcoma is surgical excision of the afflicted tissue. Chemotherapy is frequently given as a follow-up to lower the likelihood of the cancer coming back.

• Chemotherapy: When a tumor has to be reduced, or the disease's course slowed, chemotherapy is frequently utilized. It can also be administered following surgery to lower the possibility of the cancer coming back.

• Radiation therapy: Radiation therapy can be used to shrink the tumor and relieve symptoms in dogs with inoperable or advanced cases of hemangiosarcoma.

• Supportive care: Medications to manage pain, such as MELOXIDYL and DERAMAXX, can help improve the quality of life for dogs with hemangiosarcoma. Also, skin sensitive prescription foods may be prescribed for your dog.

The outcome of treatment for hemangiosarcoma in dogs can vary, depending on the stage and extent of the disease, as well as the overall health of the dog. In general, the likelihood of a successful outcome can be greatly increased by early discovery and timely treatment.
