OBJECTIVES:
I. To evaluate the impact of SAMe on hot flash scores in women with a history of breast cancer or women who do not wish to take estrogen therapy for fear of increased risk of breast cancer.
II. To evaluate the toxicity of SAMe in this study population. III. To evaluate the effect of SAMe using quality-of-life (QOL) measures.
