Gastrointestinal cancer refers to malignant conditions of the GI tract and accessory organs of digestion including the esophagus, liver, biliary system, pancreas, small intestine, large intestine, rectum, and anus. Symptoms refer to the infected organ and can involve obstruction, irregular bleeding, or other complications related to it.
Diagnosis also includes endoscopy, followed by a biopsy of suspicious tissue. Treatment depends on the location of the tumor as well as the type of cancer cell and whether it has penetrated or spread to other tissues.
