How are benign tumors of the liver detected?
Most of these tumors, which usually do not cause any symptoms, are incidentally detected during ultrasound examinations or other imaging studies. In rare cases, a biopsy may be required to determine whether the tumor is benign.
What are benign tumors of the liver? How are they treated?
Simple cysts
They are benign liver lesions with no risk of malignant transformation and do not require any medical or surgical intervention.
Hemangiomas
Hemangiomas are vascular clusters formed within the liver tissue that carry no risk of malignant transformation and do not require medical or surgical intervention unless they cause discomfort to the patient.
Focal nodular hyperplasias
Focal nodular hyperplasias, which are seen nine times more frequently in women than in men, are benign liver lesions with no risk of malignant transformation and do not require medical or surgical intervention.
Adenomas
Adenomas are lesions seen ten times more frequently in women than in men and generally carry no risk of malignant transformation. If the diameter of an adenoma is smaller than 5 cm, it does not carry a risk of malignancy; however, its size should be monitored annually. Lesions larger than 5 cm carry a risk of malignant transformation and therefore require surgical removal.
Hamartomas
They are benign liver lesions with no risk of malignant transformation and do not require any medical or surgical intervention.
