Hi Alex.
I am so sorry that your dad is going through this. Seeing our parents going through something so difficult, no matter what it is, is an extremely scary and heartbreaking experience, that no words can describe. My mom was diagnosed with HCC due to cirrohis from Hepatitis B, last June (2012). That was the worst day in my life...I remember hearing such a fear in my mom's voice when she told me they "found a suspicious lesion" on her MRI, the sound of her voice at that moment, will never leave my mind. My mom was scanned 2 times a year via MRI with contrast as well as with an ultrasound in between. Her last MRI the November prior (2011) was clear. It was a total shock. Her doctor refused to biopsy the "suspicious" lesion since there was more risk (bleeding due to low platelets, etc) with a biopsy. He did the "watch and see" approach, although the Dr. was almost 99% sure it was HCC. Since my mom had Hep B, cirrohis, as well as the "suspicious lesion" showed "washout" on the scan, he was most certain that it was HCC...BUT...her doctor also tried to convince us that the HCC could potentially be a positive thing. Since the lesion was discovered at 9mm she didn't qualify to get extra meld points, however once the lesion grew to 2.0cm...her meld jumped from 12 to 22 which gave her a better opportunity of getting a liver transplant. We dual listed my mom in December and in April of 2013, she was blessed with a donor. We are forever grateful to my mom's donor and donor family. Tomorrow my mom will be 4 months post transplant and it still feels surreal. I understand where your coming from when you describe your nightmares and your fears. Continue to be strong for your dad and for your family. Continue to advocate for your father, demand answers and ask questions. Make sure your dad authorizes you to speak directly to his doctors/team members. I am sure your dad and mom are overwhelmed with all that is happening...its only natural. Take your dad for a second opinion...one facilities approach may be diffferent from another's.
My hubby's best friend is an interventional radiologist (one of the top in his profession) and he actually tried to discourage me from having my mom dual listed and get a transplant. I never listened to his "professional" advice. And I am so happy, I didn't. Do what your heart and mind tell you until your satisfied you did your best. If you don't like what your being told, leave no stone unturned.
I am sorry for rambling on and on...I just want to encourage you, that there can hopefully be a positive outcome for your dad. I will say a prayer that your dad and you get some answers soon.
