The expression lobulated breast pattern should mean that a lobulated mass is visible in the breast, which is mostly seen in lobulated tumors of the breast. Lobular tumors of the breast, or lobulated tumors, are fibroepithelial tumors of the breast, which are composed of both fibrous and epithelial components, including benign, malignant, and junctional tumors. Junctional tumors are easy to recur locally when surgical excision is incomplete; malignant tumors often metastasize and have a poorer prognosis, so they should be taken seriously. Lobular breast tumors are usually mainly treated by surgery, and surgical treatment, regardless of its nature, should be cut cleanly, with a certain degree of safety, to a certain range from the tumor, cut more widely, with surgical resection as the mainstay. It is recommended to consult the hospital as early as possible and standardize the examination and treatment.
