Introduction
Liver nodules less than 20 mm may indicate liver cancer, although benign lesions cannot be ruled out. Liver cancer is a malignant tumor disease that may be triggered by factors such as hepatitis B virus infection, cirrhosis, and genetic predisposition. When a liver nodule is less than 20 mm, it might be liver cancer, but it is generally in the early stage, with no tumor cell dissemination or metastasis typically observed.
In general, a liver nodule measuring less than 20 mm may be indicative of liver cancer, but benign lesions cannot be ruled out. The specific analysis is as follows:
1. Liver Cancer
Liver cancer may be a malignant tumor caused by factors such as hepatitis B virus infection, cirrhosis, or genetic predisposition. A liver nodule smaller than 20 mm could represent liver cancer, typically at an early stage, when tumor cell dissemination or metastasis has not usually occurred. Patients may be treated with partial hepatectomy.
2. Benign Lesions
If the liver nodule—less than 20 mm—is due to benign conditions such as abnormal hepatocyte proliferation or fibrous tissue hyperplasia caused by viral infections, it may not be liver cancer. In such cases, patients can follow medical advice to use medications such as adefovir dipivoxil tablets, glutathione for injection, or entecavir dispersible tablets.
Patients are advised not to initiate treatment blindly before the exact nature of the liver nodule is confirmed. Diagnosis should be made using methods such as magnetic resonance imaging (MRI), liver biopsy, and complete blood count, followed by targeted treatment accordingly.
