What is Gastrointestinal Stromal Tumour?The gastrointestinal stromal tumour is a rare type of cancer that originates from the uncontrolled division or multiplication of cells found in any part or organ of the gastrointestinal tract i.e. stomach, small intestine, large intestine, rectum, and anus. It usually develops in the stomach and small intestine but can also develop anywhere in the gastrointestinal tract. The gastrointestinal stromal tumour is a rare tumour and accounts for less than 1% of all types of stomach and intestinal tumours. It is more common in females than males and commonly affects children and young adults.
Disease CausesThere is no well-known cause, however, certain hereditary diseases such as neurofibromatosis type 1 (NF1) and the Carney triad are considered responsible for the development of gastrointestinal stromal tumours.
