Seed Implants (Low Dose Rate Brachytherapy)
Seed Implant Brachytherapy involves the use of tiny radioactive isotopes called "seeds" that are permanently placed in the body. This form of treatment controls the dose and reduces exposure to the normal healthy tissues that surround the tumor. The relative amount of radiation is very low and over a period of time, implanted seeds lose their radioactivity and can remain in the body. In the early stages of prostate cancer for example, seed implantation is often used as a stand alone treatment.
