For liver nodules with normal liver function and alpha-fetoprotein, further examination can be done to determine the benign or malignant nature. If the nodules are benign, follow-up and surgical resection can be chosen; if they are malignant, surgery and other treatments should be chosen. For liver nodules with normal liver function and alpha-fetoprotein, further tests such as nuclear magnetic examination can be performed to assist the judgment. For benign nodules, such as hepatic hemangioma and hepatic cysts, when the nodules are relatively small and do not affect the patient much, they can usually be followed up regularly; if the nodules are too large and show signs of compression, they should be surgically resected. For malignant nodules, such as hepatocellular carcinoma or metastatic carcinoma, even if the liver function and alpha-fetoprotein are normal, they should be treated as soon as they are detected, and the main treatment is comprehensive treatment based on surgical resection, and usually hepatocellular carcinoma is not sensitive to radiotherapy. If liver nodules are found during examination, it is recommended to go to regular hospitals in time for consultation, and after the cause of the disease is clarified, targeted treatment should be carried out under the guidance of doctors in order to minimize the adverse effects of the disease.
