Our Procedure

breast microseed sources
A precise, convenient and effective breast cancer treatment option

Breast Microseed Treatment is a minimally invasive, post-lumpectomy outpatient radiation option for women with early-stage breast cancer, involving the permanent implantation of low-dose rate Pd-103 seeds. It’s proven safe and effective with more than 10 years of clinical results. Peer-reviewed publications show that outcomes are comparable to other current post-lumpectomy radiation options, and side effects are milder and less frequent.  As it’s a single outpatient procedure that’s completed in about an hour, you can offer patients the convenience of a therapy that’s One Time, One Hour. 


Key highlights:

  • One-time radiation therapy that’s more convenient for the patient

  • LDR brachytherapy for breast cancer.  Already proven to treat prostate cancer, successfully adapted for the breast 

  • Published 5-year outcomes demonstrate effectiveness comparable to external beam radiation therapy

  • Innovative, FDA-cleared device / needle guidance template

  • Ultrasound guided procedure. CT-based computer-generated treatment plan

  • Inclusion in a national patient registry
