Diagnosis of stomach cancer usually involves several steps. Initially, a healthcare provider will take a medical history and perform a physical examination. If stomach cancer is suspected, further tests may include:
Endoscopy: A thin, flexible tube with a camera (endoscope) is inserted through the mouth to examine the stomach lining. Biopsy: During an endoscopy, a small sample of stomach tissue may be taken for laboratory analysis. Imaging tests: Tests such as CT scans, PET scans, and X-rays can help visualize the stomach and detect cancer spread.
