Strontium-89 therapy for painful osseous metastatic prostate and breast cancer.

Strontium-89 chloride is a radiopharmaceutical that localizes to actively forming new bone, such as metastatic bone lesions from prostate and breast cancer. It provides effective systemic endo-osseous local radiation therapy to these painful lesions.
