- • Stools should be examined for hidden blood. The color may be abnormal. If they are white or clay-colored, the
- bile duct is obstructed.

- Imaging
- • Abdominal ultrasound . Ultrasound is also used at surgery to locate the exact borders of the tumor .
- • CT scans may not detect small tumors but may identify pancreatic masses, liver metastases, enlarged lymph
- nodes and fluid in the abdomen (ascites).
- • MRI may complement the CT scan.
- • PET (positron emission tomography) imaging is an experimental method for diagnosis and evaluation for liver
- metastases.

- Endoscopy and Biopsy
- • ERCP (endoscopic retrograde cholangiopancreatography) involves placing a gastroscope into the stomach and
- inserting a tube into the opening of the pancreatic duct.
- • For a definite diagnosis, a biopsy is essential. Tissue can be drawn out with a fine needle (FNA) inserted into
- the tumor using CT guidance (diagnostic in 80 percent of cases). This will be necessary to differentiate
- pancreatic cancer from benign pancreatitis or pseudocyst, islet cell carcinoma or lymphoma.
