Overview

What this centre covers

Digestive (gastrointestinal) cancers can affect any part of the tract — the food pipe, stomach, liver, pancreas, gallbladder, bile duct, small intestine, colon and rectum. Caught early and treated by an experienced super-specialist team, many of these cancers are curable. This centre explains each one in plain language and links you to the right care.

Topics

01Liver Cancer Liver Cancer

Liver cancer is a malignant tumour arising in the liver, often on a background of cirrhosis or hepatitis. When caught early it can be treated with surgical resection or transplantation, offering the best chance of cure.

02Pancreatic Cancer Pancreatic Cancer

Pancreatic cancer is an aggressive tumour of the pancreas that often causes few early symptoms. Early-stage disease may be cured with major surgery such as the Whipple operation, combined with chemotherapy — making prompt, specialist assessment vital.

03Gallbladder Cancer Gallbladder Cancer

Gallbladder cancer is an uncommon but serious tumour, sometimes discovered unexpectedly after routine gallstone surgery. Early-stage disease is treated with an extended (radical) surgical removal, which offers the best chance of cure.

04Stomach (Gastric) Cancer Stomach (Gastric) Cancer

Stomach cancer arises in the lining of the stomach and often causes vague early symptoms such as indigestion and reduced appetite. Curative treatment is surgical removal (gastrectomy) with lymph-node clearance, frequently combined with chemotherapy.

Learn more
05Colon Cancer Colon Cancer

Colon cancer develops in the large intestine, most often from polyps that grow slowly over years and can be removed during colonoscopy before they turn cancerous. Caught early, surgery offers a high chance of cure — which is why screening saves lives.

06Rectal Cancer Rectal Cancer

Rectal cancer affects the last part of the large bowel. Thanks to modern sphincter-preserving surgery, often combined with chemo-radiotherapy, most patients can be cured while keeping normal bowel function and avoiding a permanent stoma.

07Neuro-Endocrine Tumour (NET) Neuro-Endocrine Tumour (NET)

Neuro-endocrine tumours (NETs) are usually slow-growing tumours arising from hormone-producing cells in the digestive tract and pancreas. Many are curable with specialised surgery, and even advanced NETs can often be controlled for years.

08 GIST (Gastrointestinal Stromal Tumour)

GISTs are rare tumours that grow in the wall of the digestive tract, most often the stomach. They are treated by precise surgical removal — frequently by keyhole surgery — and, when needed, highly effective targeted (oral) therapy.

Don't ignore

Why this matters

Most GI cancers are silent in their early, most curable stage. By the time obvious symptoms appear, the disease can be advanced. Knowing the warning signs — and acting on them quickly with the right tests — is the single biggest factor in a good outcome.

Common symptoms to watch for

  • Unexplained weight loss
  • Persistent abdominal pain
  • Blood in stool or black stools
  • Difficulty swallowing
  • Change in bowel habits
  • Jaundice (yellowing of skin/eyes)
  • Persistent bloating or fullness
  • Loss of appetite
