What is Gastrointestinal cancer?
'''Gastrointestinal cancer''' refers to [[malignant]] conditions of the [[Human gastrointestinal tract|gastrointestinal tract]] (GI tract) and [[accessory organs of digestion]] including the: * [[esophagus]] * [[stomach]] * [[biliary system]] * [[pancreas]] * [[small intestine]] * [[large intestine]] * the [[rectum]] and [[anus]]. The symptoms relate to the organ affected and can include [[obstruction]] (leading to difficulty swallowing or defecating), abnormal [[bleeding]] or other associated problems. The diagnosis often requires [[endoscopy]], followed by [[biopsy]] of suspicious tissue. The treatment depends on the location of the tumor, as well as the type of cancer cell and whether it has invaded other [[Tissue|tissues]] or spread elsewhere ([[Metastasis|metastasic]]). These factors also determine the [[prognosis]]. [[Category:Cancer]] {{med-stub}}
