Breast nodules are a large group of diseases, including benign nodules and malignant nodules. Treatment includes the following: 1. Malignant nodules: common treatment is surgery, and after surgery, the treatment is enhanced by chemotherapy, radiotherapy and medication; 2. Benign nodules: larger benign nodules, or tumors less than 1 cm, but the tumor keeps developing during the follow-up, surgery is recommended. Other than that, benign hyperplastic nodules, or even benign tumor nodules, can be followed up for a period of time without too much worry.
