Summary
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using
tamoxifen may fight breast cancer by blocking the uptake of estrogen. Chemotherapy uses
different ways to stop tumor cells from dividing so they stop growing or die.
PURPOSE: Phase III trial to study the effectiveness of tamoxifen following surgery and
chemotherapy in treating women who have stage I breast cancer at high risk of recurrence or
stage II or stage III breast cancer.
