Throughout the study they carefully monitored the women to detect any breast cancer. Women with stronger bones had a higher risk of developing breast cancer. Also, the stronger the bones of the women diagnosed with cancer, the more serious the stage of cancer at diagnosis. Whatever causes bones to remain strong may also cause a higher risk of breast cancer. However, this doesn't mean that something in strong bones directly increases breast cancer risk.
Most scientists point their finger at estrogen as the contributing factor for both.
High estrogen levels over time both strengthen bone and increase breast cancer risk. How to benefit from estrogen's fortification of bones but avoid its stimulation of breast tissue is a major challenge of current research. About two-thirds of women who have had breast cancer experience hot flashes . Many of these women are looking for safe and effective ways to feel and function better, and health food stores are full of herbal remedies that claim to work. Black cohosh is one of them.
