Overview of Canine Hemangiosarcoma. Hemangiosarcoma is a malignant cancer of the cells that form blood vessels. Because these tumors start in blood vessels, they are frequently filled with blood. Consequently, when a blood-filled tumor ruptures, it can cause problems with internal or external bleeding.
Hemangiomas and hemangiosarcomas are common in dogs. Lymphoid cancer is common and the spleen may be involved along with other parts of the body. In dogs, the prevalence rate is 13-24 cases of all types of lymphosarcoma per 100,000 dogs at risk. Although pups as young as four months may have these cancers, 80% of cases occur between the ages of 5 and 11 years.
