Male breast tumors that are benign are generally not serious, while male breast cancer that is malignant is more serious. Male breast tumors that are benign such as breast fibroma, intraductal papilloma, breast hemangioma, breast lipoma, breast neurofibroma, breast granulosa cell tumor and other benign tumors are generally not serious and can be cured by surgical excision. Only a small portion of intraductal papillomas may have a certain risk of malignant transformation, and appropriate surgical methods need to be chosen in treatment. If male breast tumors are malignant, such as breast cancer, they are often detected late due to the lack of knowledge of breast cancer among men, resulting in late staging, high tumor grade and poor prognosis at the time of diagnosis. It is recommended that patients should make a comprehensive judgment of their conditions based on the results of imaging and pathology examinations, and consult the doctor in time to choose the appropriate treatment.
