What is Strontium-89 used for?

Strontium-89 (Sr-89) is a radioactive isotope primarily used to relieve bone pain in patients with bone metastases. It is selectively absorbed by the bones and releases beta particles, which can destroy cancer cells and reduce pain caused by cancer spreading to the bones.

During treatment, strontium-89 helps improve patients' quality of life by reducing tumor burden in the bone marrow. This therapy is typically part of palliative care aimed at controlling symptoms rather than curing the disease.

When administering Sr-89 treatment, doctors determine the appropriate dose based on each patient's specific condition and monitor for potential side effects. After treatment, patients need regular blood tests to monitor their body's response.
