My husband was diagnosed with Cholangiocarcinoma last Dec. He's had several months of chemo and also immunotherapy. The past few months he has just been doing the Immunotherapy. He had over 15 tumors in his liver and now is down to 1. We give all the thanks to Jesus. We have been told this is uncommon to see in this kind of diagnosis. Last week he had the tumor ablated and will get a scan in a few weeks to see the results of this and if all tumors are gone now. We also pray the tumors do not return. I share your pain. I hope and pray your husband will pull through this.
