Treatment of neuroendocrine tumours is discussed
Up to 400 people have been taking part in a conference in Belfast looking at the research and treatment of a rare, but fast-growing type of cancer.
Neuroendocrine tumours are the fastest growing cancer group worldwide.
The three-day conference is the first time patients, doctors and scientists have come together under one roof in the UK to discuss their treatment.
Belfast's Royal Victoria Hospital has one of only two diagnostic labs for this type of tumour in UK.
Neuroendocrine tumours are cancers of the interface between the endocrine (hormonal) system and the nervous system.
They occur most commonly in the digestive system but can occur in other parts of the body.
