Which radioisotope is used for the treatment of metastatic bone cancer?

Correct option is B

Strontium-89 is a radioisotope commonly used in the treatment of metastatic bone cancer. It is used as a radiopharmaceutical to target and relieve pain in bones affected by cancer metastasis, as it mimics calcium and is absorbed by bone tissue.

Strontium-89 emits beta radiation, which helps in reducing the bone pain caused by metastases and provides palliative relief to patients. It is specifically used for bone pain management in conditions like prostate cancer and breast cancer.

• Carbon-14: Used primarily in radiocarbon dating.
• Phosphorous-32: Used in the treatment of certain types of leukemia, not bone cancer.
• Iodine-131: Primarily used for treating thyroid cancer and hyperthyroidism.
