In brief: No

Tamoxifen is a selective estrogen receptor modulator (serm) that is used to treat/prevent breast cancer.
Evista (raloxifene) is also a serm and it is used to treat/prevent osteoporosis (it also reduces the risk of invasive breast cancer in at risk women). Tamoxifen does not cause osteopenia or osteoporosis. Tamoxifen has been shown to preserve bone.
