medical procedure
Also known as: internal radiation therapy

Quick Summary

Brachytherapy is a medical procedure that uses radiation therapy to treat cancer. In this type of therapy, the source of radiation is placed directly within or very close to the tumor or affected tissue. This method allows for a high dose of radiation to be delivered to the cancerous cells while minimizing damage to the surrounding healthy tissues. Brachytherapy is also known as internal radiation therapy. Radioactive isotopes such as iridium, cesium, gold, and iodine are sometimes used as sources. This technique can be delivered via tubes, needles, grains, or wires.123
