Abstract
This was a case of a 35-year-old female, who exhibited a nodule in swelling lymph nodes and pulmonary metastasis. In the left breast D area, a mobile poor mass of about 6cm size was located, which led to the diagnosis of
carcinoma of the breast. For neoadjuvant chemotherapy, TC 4cycle and EC 4cycle were administered, which led
to disappearance of the left axillary lymph node and the lung metastasis; this case was determined as cCR. For
cases of young breast cancer, the chemotherapies must be cautious in consideration of fecundity. However, the
priority of treatment must be seriously considered when a metastatic site contributes to a vital prognosis.
