Your radiation therapy options
Radiation treatment can be given internally (placed inside of your body -prostate seed implants, brachytherapy, mammosite) or externally (from the outside of your body – 3-dimensional radiation, IMRT, SRS, etc.). When radiation therapy is given internally it is called an invasive treatment option, since requires the entry of a needle, catheter, or other instrument into your body. When radiation therapy is given externally it is a noninvasive treatment option, since it similar to giving you an X-ray.
Dr. John G. has been trained and has experience in all radiation treatment options mentioned on this page; however based on his experience non-invasive externally delivered radiation, especially IMRT, has proven to have a higher curative rate and a lower incidence of side effects. It is for this reason that he does NOT do prostate seed implants, brachytherapy or mammosite. Instead he requested Texas Oncology to purchase the Trilogy linear accelerator, such that he can treat patients with IMRT via a highly accurate machine.
In 2004, Varian introduced the Trilogy linear accelerator, which allowed, for the first time, patients to receive the following non-invasive external beam therapies from one machine:
- 3D conformal radiation therapy
- Intensity-modulated radiation therapy (IMRT)
- Electron therapy
- Conformal arc therapy
- Gated radiotherapy (GATING)
- Image-guided radiation theapy (IGRT)
- Single-session or fractionated stereotactic radiosurgery (SRS)
- Intensity-modulated radiosurgery (IMRS)
