A physical exam: A thorough physical examination will be carried out, after taking a detailed history of your symptoms.
Endoscopy: Usually upper gastrointestinal endoscopy i.e. UGI scopy is performed, wherein an endoscope a thin tube with a camera at its end will be inserted through your mouth into the oesophagus and stomach, to rule out any abnormal growth or ulceration.
Biopsy: A biopsy is performed at the time of UGI scopy to determine the type of stomach cancer.
Blood tests: Routine blood tests will be taken along with special tests to determine tumour marker levels eg. CEA, CA 19.9
CT scan: A CT scan of the chest, abdomen and pelvis is done to determine the stage of disease; which in turn help decide on the best treatment approaches for the patient.
PET CECT scan: A PET CT scan is recommended in advanced or recurrent cases to rule out the spread of cancer to other sites, eg lungs, liver, bone, etc.
Diagnostic laparoscopy and biopsy: In advanced cases, a diagnostic laparoscopy is done to document the spread of the disease, and a biopsy is also executed simultaneously.
