Brachytherapy (Internal Radiation Therapy)
Brachytherapy treats cancer by placing tiny radioactive seeds inside the body, directly into or next to the target area. The technique has proven to be a powerful treatment option for many cancers of the prostate, cervix, endometrium, breast, skin, bronchus, esophagus, and head/neck, as well as soft-tissue sarcomas and several other types of cancer. There are two common techniques available to the physician when administering Brachytherapy: LDR and HDR.
LDR (Low Dose Rate) Brachytherapy
LDR uses sealed, low-strength radioactive seeds about the size of a grain of rice to deliver radiation to the target. These seeds are permanently implanted in the body. As the seeds emit radiation, they reduce in strength and in a few weeks no longer emit any measurable amounts of radiation.
HDR (High Dose Rate) Brachytherapy
HDR uses higher-strength radioactive sources (compared to LDR) to provide radiation to the target. As opposed to LDR, these sources are only implanted in the body temporarily.
