Unlike standard conventional breast radiotherapy, this approach treats only 2 cm of tissue beyond the borders of the lumpectomy cavity instead of the entire breast. Large-scale clinical trials have shown that breast conservation therapy, involving lumpectomy and radiation therapy, results in survival rates equivalent to those seen with mastectomy. Survival rates did not differ between patients treated by radiation, lumpectomy or mastectomy. Seventy-six of them were followed for 83 months following treatment by lumpectomy only (n 21) lumpectomy and radiotherapy (n 27), or mastectomy (n 28). These preferences may be linked to differences in geographic access to radiation facilities across regions, because of the need for postoperative radiation following lumpectomy. A comparison of ink-directed and traditional whole-cavity re-excision for breast lumpectomy specimens with positive margins. Following insertion of the balloon into the lumpectomy cavity, the balloon is inflated via one of the lumens with sterile water and contrast material. Who can technically have a lumpectomy up-front but whose physical appearance will be less damaged if primary systemic therapy is given first. In breast conservation therapy, radiation therapy is used in combination with lumpectomy to reduce the probability of local recurrence. A biologically compatible contrast material is injected into the lumpectomy cavity under ultrasound guidance, revealing its shape and extent. In nine women with tumors averaging 1.2 cm, cryoablation was performed followed by lumpectomy 3 weeks later. With this approach, after-loading catheters are placed through the breast tissue surrounding the lumpectomy cavity. The final component of geometric uncertainty is the potential for the lumpectomy cavity to change shape and/or position independently of the surrounding breast tissue. As in similar studies, breast radiation following lumpectomy has a significant impact on in-breast recurrence but not on survival.
