Nodules on the liver are not serious if they are benign, but are serious if they are malignant and need to be seen by a doctor in time. 1. Benign nodules: If the nodules are detected to be benign by CT of the liver or puncture biopsy of the liver nodules, they are usually not serious. Benign nodules generally do not cause liver malfunction or metastasis, so dynamic observation is recommended. 2. Malignant nodules: If the liver nodules are detected to be malignant, and if there is a history of hepatitis B virus and the nodules are large or obviously growing, this is more serious, and it is recommended to consult a doctor in time to clarify the situation and give targeted treatment. In daily life, we should pay attention to eat a light diet, moderate exercise, maintain a good state of mind, and regular body checkups; the occurrence of uncomfortable symptoms, timely consultation, so as to avoid delaying the condition.
