A lobulated breast nodule suggests that clinically it may be a lobulated tumor. Foliated tumors are not a qualitative tumor name, but are named based on the microscopic pathomorphology and are classified as benign, junctional (between benign and malignant), and malignant. One characteristic of this tumor is that lobulated tumors, whether benign or malignant, have the potential for local recurrence. Junctional and malignant may metastasize to other organs such as lungs, bones and liver, whereas distant metastases from benign lobulated tumors are relatively rare. It is because of the susceptibility of lobulated tumors to local recurrence that extended resection is required once a lobulated tumor is diagnosed. For the first local recurrence of lobular tumor, it can be considered to extend the excision locally again, but to ensure a sufficient safety distance, if recurrence, it is recommended to do total mastectomy. So it is said that once abnormalities occur in the breast, it is necessary to seek medical treatment as early as possible for early diagnosis and early treatment.
