Gastrointestinal cancer refers to the group of cancers that affect the digestive system which includes cancers of the oesophagus, gallbladder, liver, pancreas, stomach, small intestine, bowel and anus. Symptoms of Gastrointestinal cancer related to the organ affected and can cause difficulty in swallowing or defecating, abnormal bleeding or other associated problems. Diagnosis of Gastrointestinal tumours usually requires endoscopy, followed by biopsy of suspicious tissue. Treatment for Gastrointestinal cancer will depend on the type of cancer, the stage or its development, and other health factors. Treatment commonly includes surgery, chemotherapy and radiation therapy. The treatment depends on the location of the tumour, as well as the type of cancer cell and whether it has invaded other tissues or spread elsewhere. Gastrointestinal cancer is the most common form of cancer. More than 24,000 Australians are diagnosed with it each year and 33 Australians die of it each day. Gastrointestinal cancers do not discriminate between men and women.
