What is Hemangiosarcoma? Hemangiosarcoma is a type of cancer that affects the cells that line the walls of the blood vessels in pets. It is most common in dogs, but can also occur in cats and other animals. It is a very aggressive cancer and has a poor prognosis, with most dogs surviving less than six months after diagnosis. Hemangiosarcoma usually affects the spleen, liver, heart, and skin. Signs of the disease may include bleeding from the nose or mouth, pale gums, lethargy, weakness, rapid breathing, and abdominal swelling. If the tumor is in the spleen, a sudden onset of abdominal pain, collapse or even death may be seen.

Diagnosis of hemangiosarcoma is usually done with a biopsy or imaging tests such as an ultrasound or CT scan. Treatment may include surgery to remove the tumor, chemotherapy, and/or radiation therapy. Scheduling a consultation with a veterinary oncologist is the best way to find out more information about these treatment options and how they may help improve your pet’s duration and quality of life.

If your pet has been diagnosed with hemangiosarcoma, it is important to provide them with the best possible care. This includes providing them with plenty of rest and a nutritious, high-quality diet. Pain medications may also be necessary to help manage any discomfort your pet may be feeling. Some supplements may help reduce the risk of bleeding. It is also important to monitor your pet closely for any changes and report them to your veterinarian.

Unfortunately, despite treatment, the prognosis for hemangiosarcoma is typically poor, and most pets do not survive. Because hemangiosarcoma is so aggressive, it is important to be aware of the signs and symptoms so that you can seek treatment as soon as possible. If you suspect your pet may have hemangiosarcoma, it is important to see your veterinarian right away. Early detection and treatment are key to reducing the risk of emergency situations and giving your pet the best chance of survival.
