Pancreatic cancer is tested through a combination of methods including imaging tests, blood tests, and tissue sampling (biopsy). Common imaging tests include ultrasound, CT scans, MRI, and sometimes PET scans, which help visualize the pancreas and detect tumors. Endoscopic ultrasound (EUS) involves inserting a tube with an ultrasound device into the digestive tract to get detailed images and can also be used to take tissue samples for biopsy. Blood tests can detect tumor markers like CA19-9, which help indicate the presence of cancer. Additionally, a biopsy is often done to confirm the diagnosis by examining tissue samples under a microscope. Other specialized tests like ERCP allow doctors to see the pancreatic ducts and obtain samples, assisting in diagnosis and treatment planning.

Key Tests for Pancreatic Cancer

• Imaging Tests: Ultrasound, CT scan, MRI, PET scan, Endoscopic Ultrasound (EUS)
• Biopsy: Tissue samples taken during EUS or via fine needle aspiration through the skin
• Blood Tests: Tumor markers such as CA19-9 and sometimes CEA
• Specialized Tests: ERCP to visualize pancreatic and bile ducts and obtain biopsies if needed

These diagnostic tools are used in combination to detect pancreatic cancer, determine its extent, and guide treatment decisions.
