Liver cysts might possibly undergo malignant transformation. Liver cysts are commonly seen and considered benign tumors of the liver. When they are small, they generally do not cause noticeable discomfort and do not require special treatment. However, regular follow-up ultrasound exams are still necessary to dynamically observe any changes in the condition. This is because liver cysts might potentially undergo malignant transformation, especially under conditions of repeated inflammatory stimulation or significant liver burden. Under these circumstances, the cyst might show rapid and noticeable growth and might grow too quickly. Therefore, early surgical removal is advisable for better treatment results. Additionally, in patients with larger liver cysts, local compression symptoms might occur. Even though the tumor is benign, surgical removal is recommended.
