During HDR treatment, the surgeon implants a small, temporary catheter into the lumpectomy cavity following tumor removal. Several days later, the patient returns and the HDR machine is affixed to the catheter, where treatment is delivered via radioactive seeds precisely to the area where the tumor was located.
Similar to external radiation beam therapy, the hyper-accurate HDR brachytherapy ensures the maximum radiation dose is given to cancerous tissues while minimizing exposure to the surrounding healthy tissue. The treatment is administered twice a day for five days on an outpatient basis, after which the device is removed, leaving no radioactive seeds behind. HDR can be used in conjunction with other treatment options.
Not all patients will meet the criteria for HDR treatment established from various medical societies. Tumor size, location, and other factors must be considered. Patients should speak with their physician to determine if this treatment is right for them, or contact the Sister Diane Grassilli Center for Women's Health at 415.750.HERS.
The Sister Diane Grassilli Center for Women's Health also offers the most comprehensive breast imaging capabilities found in San Francisco including next-generation 3D tomosynthesis technology and Whole Breast Ultrasound. St. Mary's has been designated as a Center of Excellence by the American College of Radiology, a recognition that represents the national gold standard.
