hi. noted history of hepatitits B infection and liver tumor on ultrasound report. it is best if you consult with a doctor, preferably a general surgeon or a gastroenterologist, for physical examination and clinical evaluation. benign vs malignant tumor lesions of the liver must be ruled-out. one important thing that must be considered is hepatocellular carcinoma, which has a high risk of occurrence if you have a history of hepatitis B. other diagnostics (such as ct-scan, liver function tests, tumor markers, etc.) and management (medical and/or surgical if indications are found) will be directed accordingly. hope this helps. good day!! ~dr.kaye
