My wife Dawn (48 yrs) was diagnosed with cholangiocarcinoma December of 05, had liver resection done Jan 12th 06. There is a couple on good discussion groups on the web for cholangiocarcinoma. Cholangiocarcinoma dot org, and one at the John Hopkins site under bile duct and gallbladder cancer. Cholangiocarcinoma is considered a rare cancer and a difficult one to treat.
I wish your friend the best in this situation.
