Will hormone treatments affect bone density?
Tamoxifen may have a positive effect on bone mineral density. This can help to prevent such conditions as osteoporosis. However, it has also been found that the treatments are only effective if continued and that short-term treatments may not produce long-term bone density improvement. Hormonal treatment for breast cancer that lowers estrogen levels can also make bones weaker. Research is ongoing as to which treatments increase the chances of bone loss and this is something which should be discussed with your doctor.
