Breast nodule biopsy initially benign and then further examination can improve the diagnosis rate, and if the breast nodule produces malignant changes can also be detected and treated in time. Breast nodules are a common symptom caused by breast diseases, including benign and malignant breast nodules. The cause of breast nodules is still unclear, so if you find breast nodules in your daily life, you must go to a regular breast specialist hospital or a comprehensive breast department for appropriate diagnosis and to clarify the nature of the breast nodules. If the biopsy initially clarifies that the nodule is benign, attention should be paid to determine whether the benign nodule has the possibility of malignant transformation, and it is necessary to do further examination. Once it is found that the nodule has the tendency to be malignant, it needs to be surgically removed in time, even if there is no malignant transformation, the nodule should be removed within a certain period of time, so as to avoid the possibility of the malignant transformation of the benign nodule. If further examination reveals that the nodule has become malignant, that is, breast cancer, etc., timely surgical resection is also needed. If it cannot be resected, especially for patients with advanced tumors, local radiation therapy or systemic chemotherapy can be carried out to alleviate the manifestation of the tumor and prolong the patient’s life. Patients should not judge or diagnose on their own according to the result of one examination, but should follow the doctor’s instruction to carry out the corresponding examination, and the doctor will analyze and diagnose clearly according to the specific situation.
