Despite the range of classifications of MCB, treatment options are standard with other breast cancers. If the tumor is diagnosed early, breast-saving surgery could be an option, although this is relatively uncommon. In non-metastatic MCB, the most common treatment is mastectomy. If the tumor is metastatic, surgery is no longer a viable option, and treatment generally defaults to aggressive chemotherapy. Because MCB tumors are typically triple-negative, hormone therapy is not usually an option for treatment. This is directly related to its relatively poor prognosis.
