Upper GI series provides preliminary information that may help the physician determine if a stomach lesion is present and whether the lesion has benign or malignant features.
When the lesion has both, benign and malignant features, or the symptoms are present despite normal x-ray results, a further diagnostic evaluation with upper endoscopy and biopsy is necessary.
A biopsy is the only sure way to know if cancer cells are present in the suspicious lesion.
Esophagogastroduodenoscopy is the diagnostic imaging procedure of choice in the work-up of stomach cancer.
Ct scan is a useful method of detecting liver and lymph nodes metastases.
