Imaging tests that create pictures of your internal organs: These tests help your doctors visualize your internal organs, including the pancreas. Techniques used to diagnose pancreatic cancer include ultrasound, computerized tomography (CT) scans, magnetic resonance imaging (MRI) and, sometimes, positron emission tomography (PET) scans.
Using a scope to create ultrasound pictures of your pancreas: An endoscopic ultrasound (EUS) uses an ultrasound device to make images of your pancreas from inside your abdomen. The device is passed through a thin, flexible tube (endoscope) down your esophagus and into your stomach in order to obtain the images.
Removing a tissue sample for testing (biopsy): A biopsy is a procedure to remove a small sample of tissue for examination under a microscope. Most often the tissue is collected during EUS by passing special tools through the endoscope. Less often, a sample of tissue is collected from the pancreas by inserting a needle through your skin and into your pancreas (fine-needle aspiration).
Blood test: Your doctor may test your blood for specific proteins (tumor markers) shed by pancreatic cancer cells. One tumor marker test used in pancreatic cancer is called CA19-9. It may be helpful in understanding how the cancer responds to treatment. Courtesy: Mayo Clinic
