    Description:

    Neuroendocrine tumours grow in many organs of the body. The tumours start in cells that release hormones into the bloodstream (neuroendocrine cells). The tumours commonly spread from other organs to the liver (metastases), where it may not be possible to remove them with surgery. In selective internal radiation therapy (SIRT), tiny radioactive microspheres are injected into the blood vessels that supply the liver tumour. The aim is to kill the tumour cells with as little damage to nearby healthy cells as possible. It may be possible to cure the cancer or, if not, SIRT can be used to reduce tumour size, slow tumour growth or control the symptoms of carcinoid syndrome (a collection of symptoms caused by some neuroendocrine tumours that release hormones).
