Do Pancreatic Tumors Need A Needle Biopsy?

Hello! Some hospitals can carry out pancreatic tissue biopsy guided by CT or B ultrasound, or puncture biopsy under endoscopic ultrasound. The advantages are qualitative, but the disadvantages are also false negative, that is, if the puncture does not reach the lesion, the diagnosis is missed. Therefore, if the tumor is confirmed by imaging, it is not necessary to do biopsy, but can be directly operated.
