Hemangiossarcoma

Also known as: câncer dos vasos sanguíneos

O hemangiossarcoma é um câncer agressivo das células que revestem os vasos sanguíneos, afetando mais frequentemente o baço, o coração ou o fígado em cães. Os tumores são frágeis e propensos à ruptura, causando hemorragias internas súbitas que podem manifestar-se como colapso ou fraqueza por perda de sangue. Dissemina-se precoce e amplamente, e a doença costuma estar avançada quando detectada. O prognóstico permanece reservado mesmo com cirurgia e quimioterapia.
