[|Human|] I have a cyst on head of my pancreas. I have abdominal pain on right side that radiates to my back.some nausea but no jaundice or vomiting. I had gall bladder removal surgery 13 years ago so may be a result of that. Do you think it is cancerous YYYY@YYYY
[|AI|]  Any lesion in the pancreas needs to be taken seriously even if it appears completely cystic on imaging. If the CT scan shows it to be cystic then get an endoscopic ultrasound done with aspiration of the cyst fluid. Send the fluid for malignant cells and CA 19-9 estimation. If any of these is abnormal then get a surgery done for removal of the cyst as it is likely to be cancerous, else don't worry. The above procedure will be done by a gastroenterologist with a good setup and experience. Also, get a blood CA 19-9 estimation also.
