How high the risk of cancerous transformation of DN nodules in liver depends on the type of liver cancer nodules, which mainly includes sweat gland tumor, atypical hyperplastic foci, atypical hyperplastic nodules, and the risk of cancerous transformation varies with different types of nodules, as follows. 1. Sweat gland tumor: this is a kind of benign nodule, the chance of malignant transformation of benign tumor nodule is relatively low, and it can be cured after regular treatment. 2. Atypical hyperplastic foci: this type of nodule is better differentiated clinically, and is generally not prone to cancer, and even if it will become cancerous, the chance is relatively low. 3. Atypical hyperplasia nodule: initially, it may be a low-grade atypical hyperplasia nodule, if not treated in time, it may progress into atypical hyperplasia nodule, which may eventually lead to early-stage small hepatocellular carcinoma, with a relatively high probability of becoming cancerous. Clinically, liver DN nodules are usually benign, but if atypical hyperplasia nodules are detected, effective measures should be taken as soon as possible to control the progression of the disease, so as not to cause liver cancer; during the period of treatment, the patient should be re-examined once a year to understand the changes of the disease.
