Cesium Cancer Treatment

I am trying to help my sister recover from stage III Multiple Myeloma. Her femur fractured before she was diagnosed and has several other sites. She was in severe pain so we had radiation on her femur and L5. We are now on the "high pH therapy" and she is on the 15th day of cesium. I am looking for another alternative to help her. I am giving her fresh extracted vegetable and fruit juices as well as CoQ10 and other vitamins and minerals as well as Quercetin. I want to ad another immune activator and was considering MGN3. Has anyone had experience with cesium? MGN3?
