What Is a GI (Gastrointestinal) Cancer Surgeon?
A gastrointestinal (GI) cancer surgeon is a surgical oncologist who specialises in the diagnosis and surgical treatment of cancers affecting the digestive system — from the oesophagus to the rectum, including the stomach, liver, pancreas, gallbladder, bile ducts, small intestine, colon, and rectum. GI cancers are among the most common cancers globally and require highly specialised surgical expertise due to the complexity of the abdominal anatomy.

FAQ’S
How do I know if I need a GI surgeon vs a general surgeon?
If you have been diagnosed with cancer of the stomach, liver, pancreas, colon, rectum, or any other digestive organ, you should consult a specialised GI surgical oncologist rather than a general surgeon. Cancer surgery requires specific oncological training to ensure complete tumour removal with adequate margins and lymph node dissection.
