Hormone Replacement Therapy and High S Phase in Breast Cancer

Article Abstract:

Hormone therapy appears to stimulate the growth of certain types of breast cancer cells. Researchers analyzed certain characteristics of tissue samples from 331 postmenopausal women with breast cancer. Approximately half the women had used or were currently using hormone replacement therapy. Women who used hormone therapy were more likely to have cancer cells in the S phase, which is a sign of cell proliferation. However, this was only seen in women whose tumors had estrogen receptors.
