It is important to note that not every mass detected in the liver is malignant or cancerous. While some of these masses may be benign, the majority of malignant tumors are metastases that have spread to the liver from other organs. The diagnostic and treatment approach is determined by specialists based on the nature of the mass. Treatment options include surgical removal of the mass, liver transplantation, as well as methods such as radiotherapy, chemotherapy, immunotherapy, and targeted smart drug therapies.
