At Orange County CyberKnife, we strive to help our patients overcome cancer and reclaim their normal lives. We understand how devastating a cancer diagnosis can be for you or a loved one, which is why we’re proud to offer a variety of advanced cancer treatment methods to combat a wide variety of cancers and conditions. In addition to CyberKnife, Hyperthermia, and Clinac cancer treatments, we’re also proud to offer both low and high dose Brachytherapy to our patients.

High Dose Rate Brachytherapy (HDR)

HDR Brachytherapy is an extremely precise method for radiation therapy that’s effective in eliminating cancers of the skin, cervix, prostate, breast, and many other areas. Brachytherapy works by implanting an intense source of radiation directly into the tumor site, delivering high doses of radiation with remarkable precision. HDR treatment is pain-free, delivered through a computer-controlled machine in just two to ten convenient treatments. To place the radiation applicators, we simply use a wire or cable inserted into a catheter that goes into the tumor site. We can remove the catheter between treatments, helping to minimize side effects and impact on your life, and we can vary the positioning of the wire to target cancer of any shape and location.

We offer three forms of HDR Brachytherapy at our facility:

  • Interstitial Brachytherapy: Commonly used for prostate cancer, this method delivers radiation directly into the tissue.
  • Intracavitary Brachytherapy: Often used for breast, cervical, and vaginal cancers, this method delivers radiation from the cavity left behind by a recently removed tumor.
  • Episcleral Brachytherapy: This method attaches a radiation source to the eye to treat melanoma inside the eye.

Low Dose Rate Brachytherapy (LDR)

LDR Brachytherapy uses a similar method to HDR, but it uses a lower dose over a longer period of time. In most LDR treatments, we’ll implant between 50 and 100 radioactive “seeds” directly into the cancerous tissue, delivering a low, continuous dose of radiation to the tumor over the following month or so. After treatment is completed and the seeds lose their radiation, they’ll fade away with the cancerous tissue. Our radiation oncologists uses special computer planning system that uses transrectal ultrasound (TRUS) images to help design and monitor the radioactive seeds over the course of your treatment. LDR Brachytherapy offers a convenient, one-time cancer treatment solution for a variety of conditions including cervical, esophageal, head & neck, and lung cancer, but it’s most commonly used for prostate cancer.

Mammosite Targeted Radiation Therapy

If a woman opts for a lumpectomy instead of a full mastectomy, she’ll need radiation treatment after the surgery to prevent regrowth of the tumor. MammoSite internal radiation therapy is specifically designed to provide this treatment, providing a safe, effective, and targeted form of radiation designed to stave off further tumor formation. MammoSite works by inserting a balloon catheter into the cavity left behind by the tumor, then filling that balloon with a saline solution. During your treatment, your radiation oncologist will insert a tiny amount of finely calibrated radioactive material into the balloon. They’ll leave the material in for about 10 minutes, during which it’ll apply a precise amount of radiation to the tumor cavity, then remove the material between treatments. Most patients require about two treatments a day for five days. After your final treatment, we’ll simply remove the MammoSite catheter and the cavity will heal normally.
