How is stomach cancer diagnosed?
Before carrying out any test, the doctor will prepare a medical history and perform a physical examination that will inform him or her about the patient’s habits and the existence of any symptoms and signs that may lead to suspicion of stomach cancer or other conditions.
Tests for diagnosis
Besides a clinical history and physical examinations, in order to accurately diagnose stomach cancer, the physician may request additional tests.
- Endoscopy: It is the test most used in the diagnosis of stomach cancer. Endoscopy allows direct observation of the mucosa of the stomach and a more accurate assessment of the existence or not of lesions.
- Biopsy: If the doctor observes a suspicious lesion during the endoscopy, he may remove a small sample of tissue from the area. This small sliver of tissue will be analyzed by a pathologist using a microscope, allowing him or her to issue a diagnosis confirming or ruling out the existence of cancerous growth.
Other tests that can help determine the presence of stomach cancer:
- Radiographic study with contrast
- CT Scan
- Abdominal ultrasound
