Brachytherapy (Radioactive Seed Implants)

Brachytherapy, which has been available at the J. Allen Knox Radiation Therapy Center since 1998, involves placing radioactive sources directly into or adjacent to a tumor or surrounding tissue. With these sources placed, or "implanted" into the tumor, the radiation oncologist can deliver a large dose of radiation to the tumor while minimizing dose to healthy tissue. Some implants are temporary and some are permanent.

One form of permanent brachytherapy is permanent prostate seed implantation. Small radioactive seeds are permanently placed into the prostate gland. These seeds remain in the body after they have expended their radiation and they are no longer radioactive. The Radiation Oncologist will recommend the type of treatment that she believes is appropriate for each individual patient.
