What is Low Dose Rate Brachytherapy (LDR)?
Low dose rate (LDR) brachytherapy is a type of internal radiation which uses radioactive sources placed into or near cancerous tissue. It may be offered either alone or in combination with external beam radiation to treat and/or relieve symptoms associated with cancer. With LDR brachytherapy, lower doses of radiation are delivered to the targeted site over an extended period of time.
