Types
-
There are three types of hemangipsarcoma cancer: dermal, hypodermal and visceral. Visceral -- splenic or cardiac -- is the most common form. The tumors with this type of cancer are embedded in the internal organs, giving very little warning in the early stages of the disease. Life expectancy is approximately two to six months from the time of discovery.
Symptoms
-
Symptoms include such things as lethargy, loss of appetite, weight loss, difficulty breathing, pallor, nosebleeds and abdominal fluid. The symptoms may start out sporadic, becoming more constant over time as the disease progresses. There is rarely any pain associated with this cancer. In the final stages, a large tumor may rupture, leading to hemorrhage, collapse, shock and death.
Diagnosis
-
Diagnosing this form of cancer can be difficult, especially when tumors are rooted deep within the organs. Some tumors can grow to 10 pounds and can be found easily through a physical exam. X-rays are used frequently to look for smaller tumors but rarely pick up tumors in the heart. Blood is drawn to look for deficiencies in platelet count and fibrin content. It also is used check blood clotting times, which may be an indication of this form of cancer. Fluid may also be aspirated from the abdomen to look for signs of blood.
Treatment
-
This form of cancer is incurable, making treatment options somewhat limited. Small, single tumors can sometimes be removed surgically in conjunction with chemotherapy, depending on the location. This is not always feasible with older dogs in the end stages of the cancer. Medications and alternative therapies are frequently used in advanced stages to make the dog as comfortable as possible

End-Stage Canine Hemangiosarcoma
Hemangiosarcoma is a malignant, aggressive type of cancer that commonly affects the spleen and the right atrium of the heart in dogs. This form of cancer has a slow growth rate and rarely causes pain, making it extremely difficult to diagnose until it is at the end stages. It is most commonly found in older dogs and larger breeds, such as the German shepherd, golden retriever, Portuguese water dog, Skye terrier and boxer. It appears to have a genetic component. Treatment options are limited with this type of cancer in advanced stages.
