Hemangiosarcoma is an aggressive, malignant tumor of the blood vessels. Dogs are most affected by hemangiosarcoma than any other species of animals. Because the tumor affects blood vessels, this tumor is often associated with internal bleeding which can be life threatening for your pet.

Is hemangiosarcoma a serious condition in my dog?

The severity of hemangiosarcoma depends on where it is found. This type of tumor can originate in several areas with the most common sites being the spleen, heart, skin and liver. Only tumors found on the surface of the skin are considered to be curable and less serious than other areas. If the tumor is found early, complete surgical removal can cure your pet. If left to grow, cutaneous hemangiosarcoma can spread to other areas. This version of hemangiosarcoma is related to sun exposure and therefore is often seen in sparsely haired areas (such as abdomen) or in breeds with white hair. Certain breeds with white short fur, such as Dalmations or Pit Bull Terriers, are more prone to developing cutaneous hemangiosarcoma.

Hemangiosarcoma found in other locations such as the spleen and heart, is always considered a very serious disease. The reason is, this tumor spreads early and quickly so disease may be widespread before you notice any signs in your pet. This form of hemangiosarcoma is termed “visceral” hemangiosarcoma.
