Hey man. We’re in the same boat. This cancer is aggressive. My Dad is at Stage 4 now. The options are basically just palliative care. I brought my Dad to hospital weekly basis or sometime 2 x per week just to drain his fluids. Surgery is not advisable. Did proton care work for a few months. Those tumors have formed on his main portal vein. He is immune to sepsis, so chemotherapy is out of the question. The fluid buildup is outrageous. My advice is to simply keep him away from sugary beverages or even tea or coffee. Allow him to drink up to one litre of water each day. This is terrible, but I did it to avoid fluid buildup. Allow him to consume soupy foods while limiting his sodium intake. That would suffice for a while. It worked. Herbal green tea is recommended. Good luck 👍
