Unfortunately, you can't change what already is done. Keep moving forward the best that you can physically, mentally, and emotionally. That is all that you can ask of yourself. Go into tomorrow with a positive attitude. I personally am excited for your histotripsy. My liver has a lot of cancer. If/when my chemo stops working, my doctor has discussed histotripsy as an option. Please let us know how tomorrow goes ok? We are cheering you on!
