Consequently, when a blood-filled tumor ruptures, it can cause problems with internal or external bleeding.
Hemangioma and Hemangiosarcoma in Dogs. Hemangiomas are normally observed as red-to-black nodules that may appear singularly or in multiple areas. Sarcomas are cancers of connective tissue, blood vessels, or the fibrous tissue that surrounds and supports organs. When used together, these two terms refer to hemangiosarcoma, which is a cancer of blood vessels, usually occurring in the spleen, heart or skin.
