I have been diagnosed as having NASH. My mother passed away in February due to liver cancer after having NASH. I don't know what I should watch for or what I should do to convince my primary doctor that I need to see an oncologist. Without his referral, my insurance won't pay. My liver biopsy showed no cancer but I have all of the symptoms. Give me any advice on any of this you may have. I am already experiencing edema in my legs, forgetfulness, severe itching, and a lot of abdominal pain around the right side. I also have some swelling over my left abdominal area, around the spleen.
