Hi, after endocopy and biospy, I had been diagnosed with duodenal submucosal tumor . The biopsy says: Suggestive of heterotopic pancreatic tissue . Now when I went to seek a second opiniion from a doctor, he says the biopsy had been done on the suface skin of the tumor, and so I have to do enscopic ultrasound and CT scan to determine or rule out malignancy . He says there s 90% chance of it to be benign, but there s 10% chance of it being malignant as well. Which doc should I go for now, the new one or the previosu one?
