Just a short warning, not medical advice, but from our experience: my husband had a benign cyst the left lobe of his liver that was larger than yours (not sure of dimension at presentt) & 1 year after he had his gallbladder removed laparoscopically he was diagnosed with hepatocellular carcinoma - liver cancer. We will both go to our graves believing that the air needed to blow him up to see & remove his gallbladder changed the characteristics of the benign tumor to a Malignant tumor. That was April 2006. 11 years later he has had 3 treatments of radiation BBs (2006 - 2008), radiation (7 sessions) to shrink a tumor that metastasized into a rib next to his liver (2013), 14 months of Nexavar (2014 - 2015), & now he is just dealing with constant fatigue, pain, & high ammonia levels. Take care of yourself, watch your diet, & avoid any kind of surgeries that open up your torso & exposes your liver to air.
