Vascular Tumors

A vascular tumor is a growth of vascular origin, formed from blood vessels. Some are benign and some are malignant. There are different forms of vascular tumors and treatment will depend on the type, location, staging and other factors. Some tumors are benign, some are malignant. For example, angioma is a benign tumor made up of blood vessels, whereas angiosarcoma is a cancerous growth of the same cells, but is malignant.

There are various treatment options, including the ‘wait and see’ approach for slow growing tumors, chemotherapy and radiotherapy, surgical removal, targeted therapy and chemical embolization.


Because these tumors are so rare, treatment may be experimental in some cases. CRAVAT hopes to provide an insight into the different tumors and treatments, but more importantly, with the help of members’ data, to analyse and monitor these treatments so patients and doctors can better determine the most effective course of treatment.
