Hi Marion, Thank you for your welcome! To answer your question, I had a liver biopsy from which the Cholangiocarcinoma was diagnosed. I hope that answers your question. Over the last 6 months I have lost a good bit of weight and it was stomach issues that took me to the Dr., from which an ultrasound to inspect the gallbladder also showed the liver lesions. Then MRI, gastric scope, colonoscopy, and finally liver biopsy. Whew!! And now chemo.
