Patient: About 3 or 4 years ago, there were hard lumps in both breasts, which increased in size a little, without pain or itching, and without feeling anything. The examination result is bilateral breast enlargement, the examination time is in May 08, took 10 boxes of breast nourishing pellets, but did not see any effect. How can I treat it thoroughly, and will it worsen if I don’t treat it? Liu Sheng, Department of Breast Medicine, Shanghai Longhua Hospital: Herbal treatment for breast enlargement usually requires more than 3 months of treatment. In addition, it may take longer if the nodes are larger, more numerous or harder or in younger patients. The risk of breast carcinogenesis is related to the histological type of benign breast disease. Generally, non-proliferative lesions do not increase the incidence of breast cancer, while those with lobular or ductal atypical hyperplasia have a certain risk of cancer, the chance of which is about 2-3%. Therefore, the chance of breast hyperplasia becoming cancerous is not high, so there is no need to worry too much.
