Hypervascular Tumor

What is hypervascular tumor?

A hypervascular tumor is a tumor that is connected to an unusually large number of blood vessels. Because so many vessels are attached to it, a hypervascular tumor presents significant risk of bleeding. That makes removing it difficult.

Causes of hypervascular tumor

Come cancers are more likely to cause hypervascular tumors than others. They include:

  • renal cell carcinoma: a type of kidney cancer
  • breast cancer
  • neuroendocrine tumours: tumors appearing in neuroendocrine cells, or cells that receive input from the nervous system and trigger the production of hormones
  • thyroid carcinoma
  • melanoma
  • hepatocellular carcinoma: a type of liver cancer
  • Choriocarcinoma: a type of uterus cancer
  • Leiomyosarcoma: a form of sarcoma (a very rare, aggressive cancer) that affects your connective tissues — bone, cartilage, fat, muscle and blood vessels


One effective treatment for hypervascular tumors is embolization, a procedure that blocks blood flow to the tumor. Cutting off the blood flow to the tumor can cause it to shrink, making removal easier. Even if it doesn’t make removal more realistic, embolization can stop the tumor’s growth or slow it down, possibly improving a patient’s quality of life.
