Dear lisa822, Not sure what you are confused about.  Neoadjuvant chemotherapy is giving chemotherapy treatments prior to surgery to shrink a tumor and also to treat any cancer cells that may be elsewhere in the body (like adjuvant chemotherapy does after surgery).  Neoadjuvant chemotherapy is not unusual treatment of large breast tumors.  The number of cycles of treatment may be determined by several factors including the size of the tumor, the response to the chemotherapy etc.  You may want to discuss your specific concerns with your oncologist.
