A breast mass with a burr-like appearance often suggests that the mass is malignant, but it may also be benign and require further evaluation for malignant risk and management. A burr-like breast mass is a description of the edges of a mass on imaging, and refers to the presence of thin radiating lines at the margins of the mass. Malignant tumor cells are invasive, and blurred, burr-like margins are more characteristic of malignant tumor margins. Therefore, burr-like often suggests that the mass may be malignant, there may be breast cancer, breast sarcoma, etc.; may also be the emergence of gastric benign breast disease, such as breast fat necrosis, granulomatous lobular mastitis, etc.. The burr-like shape of the breast mass is a sign of suspected malignancy, and patients are advised to evaluate the risk of malignancy of the nodule in conjunction with other descriptions in the imaging report, and to follow the doctor’s instructions for further examination and treatment.
