This study will evaluate the efficacy and safety of treatment with oral capecitabine or intravenous (IV) 5-fluorouracil (5-FU), in combination with epirubicin and cyclophosphamide, prior to surgery in participants with breast cancer. The participants will receive 4 cycles of neoadjuvant Capecitabine + Epirubicin + Cyclophosphamide (CEX) or 5-FU + Epirubicin + Cyclophosphamide (FEC 100) chemotherapy during first treatment period (Period 1, Days 1-85). After 4-6 weeks of the fourth cycle of neoadjuvant chemotherapy (Day 120 +/- 7 days), breast surgery with regional lymph node dissection will be performed, followed within a maximum of 6 weeks by the second treatment period (Period 2, Days 1 to 85) when participants in both study arms will receive 4 cycles of adjuvant docetaxel 100 milligrams per meter square (mg/m\^2) by IV infusion on Day 1 of each 21-day cycle. Upon completion of the second treatment period, participants will enter the post-treatment follow-up period which will last for 5 years from the initial date of participant randomization. During this period participants will be evaluated once a year on the anniversary date of randomization.
