Gastric cancer screening

Difference between Barium examination and Endoscopic examination

Before, the major screening for gastric cancer was using barium. It is obvious that endoscopic examination, looking the stomach directly like a video camera, can provide superior detection of gastric cancer to barium examination, looking at a silhouette of the stomach.

Gastric Endoscopy

Gastric endoscopy was said to be very stressful in the past, but the evolution of the endoscopy itself, becoming more slim and soft, and the procedure change with light sedation made more safe and comfortable to receive.
