Anna,
I am so sorry about your brother's liver cancer. I know it is a scary road. My father also has two tumors, in each lobe, one 10cm and I am not sure about the other. He was not a candidate for surgery either. The hepatic aterial infusion delivers chemo straight to the liver. He is in for his second treatment today. He will be in the hospital for five days straight getting the chemo and then he will return home. We are positive with some of the results so far.
He is being treated at Baylor University Medical Center in Dallas. I don't know where you live, but you may want to get a second and thrid and fourth opinion. There are so many new treatments out there than there used to be. Don't give up hope. Seek out as much information as you can and don't be afraid to ask questions, lots of questions. Today in healthcare, you really have to advocate for yourself and your loved ones.
I hope that this helps you. Feel free to contact me anytime. You and your family will be in my prayers.
