A huge study from Britain is challenging the medical assumption that for younger women in the early stages of menopause, the risks of breast cancer related to hormone therapy are low. This medical practice has not been well studied and is without scientific foundation
The study was an observation study that reviewed relevant information on 1,129,025 postmenopausal women in the UK. The study found that the risk of breast cancer was highest for who took hormones within five years of the start of menopause. The study also indicated that women who took the therapy for a short time, less than five years, were at the highest risk
The study, published in the The Journal of the National Cancer Institute, raises serious questions about current assumptions about using hormone therapy.
