Summary
Brief summary (as posted)
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using tamoxifen may fight breast cancer by blocking the uptake of estrogen. Combining combination chemotherapy with hormone therapy may kill more tumor cells. PURPOSE: Randomized phase III trial to compare the effectiveness of tamoxifen with or without combination chemotherapy in treating postmenopausal women with stage I or stage II breast cancer that can be surgically removed.
