	Hemangiosarcoma
		Hemangiosarcomas are a form of cancer which originates in the endothelium, which is the lining of blood vessels and spleen.
		Bleeding disorders associated with hemangiosarcoma are sometimes confused with immune mediated hemolytic anemia (IMHA) because the type of anemia caused by the two conditions is very similar and early clinical signs are often very similar, as well.
		Diagnosis of hemangiosarcoma can be accomplished in a number of ways.Identification of a tumor in the spleen or heart raises a high degree of suspicion for this tumor.

		Hemangiosarcoma is a very aggressive, high-grade soft tissue sarcoma with the most common areas affected being the spleen and heart.
		Hemangiosarcoma is becoming much more common in companion dogs nowadays and I have to say I do not completely understand why, apart from the fact that dogs seem to be following their human masters more closely in the incidence of an increasing array of 20th Century diseases, the leader amongst which are cancers.
		Hemangiosarcoma could therefore be seen as an end result of a systemic and prolonged blood toxicity situation which may never have appeared without late 20th century domestication and feeding practices.

		Canine hemangiosarcoma is an incurable tumor of cells that line blood vessels (endothelial cells).
		Hemangiosarcoma is extremely indolent – that is, it develops slowly and is essentially painless – so clinical signs are usually not evident until the advanced stages when the tumors are resistant to most treatments.
		Similarly, a number of novel approaches using targeted therapies and tumor vaccines to treat canine hemangiosarcoma are in preclinical development or in the early stages of clinical testing.

		Hemangiosarcoma is one of those aggressive cancers that typically has metastasized by the time it is diagnosed.
		Hemangiosarcoma most often originates in the spleen where the tumor ruptures, showering tumor cells within the abdomen that may implant and grow.
		Because hemangiosarcoma is a cancer of the blood vessel cells, the tumor has a constant blood supply and access to blood vessels, facilitating its spread throughout the body.

	What Happened To Sophie Marie
		After five hours of testing, including xrays and ultrasound, it was certain that she had a very fast-growing cancer of the spleen known as hemangiosarcoma, and that it had spread to her lungs.
		It was large enough (bigger than half a loaf of bread) to have spread her ribs and put pressure on her heart, lungs, liver, bladder, and other organs.
		Cutaneous [versus internal, or visceral] hemangiosarcomas are more common in poorly pigmented breeds and dogs with light hair, including Beagles, Bloodhounds, white English Bulldogs, English Pointers, Salukis, Dalmatians, and Whippets.
