Detailed Description:

Breast cancer is the most commonly diagnosed malignant disease and the leading cause of cancer-related mortality among women.

Zoledronate is a bone-targeted bisphosphonate, which is used to treat osteoporosis and to reduce the risk of skeletal morbidity in patients with bone metastases. Zoledronate can also reduce the persistence of disseminated tumour cells in the bone marrow of women with early-stage breast cancer. Nowadays, consensus is emerging that certain subsets of patients with early-stage breast cancer may benefit from bisphosphonate therapy.
