    • local swelling

    • adenocarcinoma
    • difficult to diagnose and treat

    • upper abdominal pain
  13. Metastization sites of pancreatic cancer
    • duodenum
    • stomach
    • liver
  14. Diagnosis of pancreatic cancer
    • laparoscopic biopsy
    • abdominal ultrasound/CT scan
  15. Treatment for pancreatic cancer
    • palliative therapy for jaundice or gastric obstructions
    • surgery
    • chemo
