There are liver benign tumors and liver malignant tumors. Whether liver tumor 6.5cm*7.7cm can be treated with surgical oncology mainly depends on the nature of the tumor. 1. Benign liver tumors: common ones include hepatic hemangioma, which may compress the surrounding tissues and organs when its volume increases. When the volume of hepatic hemangioma increases, it may oppress the surrounding tissues and organs. Patients with obvious clinical symptoms need to consider surgical resection; when the diameter and volume of hepatic hemangioma is very small and patients have no clinical symptoms, observation and treatment is sufficient. 2. Malignant tumors of liver: for example, liver cancer, early liver cancer, surgical resection treatment is preferred, with good effect. For patients with advanced liver cancer, they often lose the timing of surgical resection of the tumor, and can not be treated by surgical operation, so they can consider comprehensive treatment such as immunotherapy or targeted therapy. Patients should go to the hospital in time if they have any discomfort in normal times to get a clear diagnosis so as not to delay the treatment.
