I am so sorry and understand the shock and confusion for all of you. My brother’s wife, my sister in law who I loved so dearly was diagnosed on her birthday week just turned 40, a time we were supposed to celebrate got the shocking news. Her diagnosis was also at stage 4 metastasis to her liver no chance of surgery due to tumour location. She went through chemotherapy which shrunk the tumour down but was on morphine all the time for serious pain. When she finished her chemotherapy she had a couple of good months but then water in her lungs and legs called aschites also new nodules rapidly grew in her stomach.
I pray your brother gets other choices and referrals to other doctors. My sister in law was declined saying that because she was so advanced they cannot release her to see other doctors for second opinion ( here in Canada) was in operable.
Time is very important she also was in so much pain could not travel. She was determined to fight and did right to the end was one year later she passed on, left behind 2 small children.
I pray for your brother and all of you I understand the pain you feel and want to help as much as possible. 🙏♥️
