Conditions & symptoms

Gastrointestinal cancer

Most people investigated for cancer symptoms don't have cancer — but the ones who do are best served by rapid diagnosis and, where it's caught early, treatment through the endoscope rather than surgery.

See a doctor promptly if you have difficulty swallowing, food sticking, unintentional weight loss, vomiting blood, black stools, or new persistent symptoms over the age of 55 — these need timely investigation rather than watchful waiting.

Symptoms that need investigating

Difficulty swallowing, food sticking, unexplained weight loss, persistent vomiting, new upper abdominal pain, anaemia, vomiting blood or passing black stools all warrant timely endoscopy. A change in bowel habit or rectal bleeding warrants colonoscopy. Private investigation means these questions are answered within days rather than months.

Dr Zeki's expertise

Upper gastrointestinal cancer and its precursors are the centre of Dr Zeki's academic career — his PhD examined the genomics of oesophageal cancer, and his clinical practice includes the endoscopic detection and resection of early cancers of the oesophagus and stomach. Detection at this stage is the difference between an endoscopic day‑case procedure and major surgery.
