<qa>  What is the final decision on the tumor size?During the study, participants will have blood tests done before each dose of chemotherapy. For participants who have not had surgery, a mammogram and sonogram will be done of the breast and armpit after completion of paclitaxel or docetaxelcapecitabine and after completion of fluorouracil, cyclophosphamide, and epirubicin FEC. These studies will help doctors to keep track of the tumor size and help with the final decision whether to remove all or part of the breast and nearby lymph nodes after completion of chemotherapy.
