Summary
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using
tamoxifen may fight breast cancer by reducing the production of estrogen. It is not yet known
if prolonged tamoxifen is more effective than shorter tamoxifen therapy following curative
treatment for breast cancer.
PURPOSE: This randomized phase III trial is studying giving tamoxifen over a prolonged period
of time to see how well it works compared to giving tamoxifen over a shorter period of time
in treating patients who have had a breast tumor removed.
