Sentinel lymph node biopsy for breast cancer

In a health care system in which decreasing costs, increasing quality, and minimizing morbidity are emphasized, new, less invasive surgical techniques are gaining popularity. Sentinel lymph node biopsy is one such procedure used to treat many types of breast cancer. By performing a biopsy of this node, which receives lymphatic drainage from the tumor, the surgeon can predict the status of all nodes in the axillary region and accurately diagnose stages of cancer, thus eliminating axillary dissection for 55% to 70% of patients. Successful outcomes result from a concerted effort among the nuclear medicine physician, radiologist, surgeon, and surgical team members.
