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.
In most cases, it's not clear what causes soft tissue sarcoma. In general, cancer occurs when cells develop errors (mutations) in their DNA. The errors make cells grow and divide out of control. The accumulating abnormal cells form a tumor that can grow to invade nearby structures and spread to other parts of the body. The type of cell that develops the genetic mutation determines what type of soft tissue sarcoma you have. Some types of soft tissue sarcoma include: Alveolar soft part sarcoma. Angiosarcoma. Clear cell sarcoma. Dermatofibrosarcoma protuberans.
