Overview
Biopsy may be helpful in the diagnosis of stomach cancer.
Endoscopy and Biopsy
- A single biopsy has a 70 percent sensitivity for diagnosing an existing gastric cancer while performing seven biopsies from the ulcer margin and base increases the sensitivity to greater than 98 percent [14].
- Superficial mucosal biopsies may be falsely negative as in linitis plastica cancers. So, the combination of strip and bite biopsy techniques should be used when there is a suspicion of a diffuse type of gastric cancer [15].
