Liver resection is a surgical procedure that involves removing a portion of the liver. This operation is typically performed to treat conditions such as liver cancer, benign tumors, or severe liver damage. The extent of the resection can vary, ranging from removing a small segment to a larger portion of the liver, depending on the patient's condition. The liver has a remarkable ability to regenerate, which means that even after a significant portion is removed, it can grow back to near its original size over time. This regenerative capacity is one reason why liver resection can be an effective treatment option for certain liver diseases.
