RecruitingDevice studyFeasibility Study for the SIRA-1000, SIRA® RFA Electrosurgical Device as an Adjunct to Breast Conserving SurgeryThis study aims to assess the safety and clinical accuracy of the SIRA-1000, SIRA® RFA Electrosurgical Device in ablating margins post-lumpectomy in patients undergoing breast conserving surgery for breast cancer. Radiofrequency ablation, or RFA, uses radio waves to create heat, that in turn, causes deliberate controlled damage to the tissue surrounding where the tumor was located. You may hear your doctor refer to this as the 'margins'. Your doctor is using this treatment to help destroy remaining cancer cells in the margins around the site of the lump.
