Brachytherapy
High Dose Brachytherapy (HDR) is delivered through catheters (tubes) to the tumor area, protecting healthy tissue. This may be administered over several treatments to deliver a high dose of radiation to the tumor, and can be delivered on an outpatient basis.Low Dose Brachytherapy (LDR) is delivered through catheters (tubes) to the tumor and is done in an inpatient hospital setting. The patient usually receives treatment over a two to three day period. This procedure allows the radiation to be delivered in a controlled manner over a relatively short time. Minimally invasive LDR can often be used in the treatment of prostate cancer through the use of prostate seed implants, tiny radioactive materials that are placed close to the tumor.
