New, noninvasive way to identify lymph node metastasis

Using two cell surface markers found to be highly expressed in breast cancer lymph node metastases, researchers have developed targeted, fluorescent molecular imaging probes that can non-invasively detect breast cancer lymph node metastases. The new procedure could spare breast cancer patients invasive and unreliable sentinel lymph node (SLN) biopsies and surgery-associated negative side effects.
