Procedure in removal of nodes more accurate in detecting remaining breast cancer

Wednesday, October 9, 2013 - 9:05am

Most breast cancer patients whose disease has spread to their lymph nodes have most of them removed after chemotherapy to determine if any cancer is present.

The Mayo Clinic researchers say a less invasive procedure that removes only the nodes most likely to contain cancer, was 91% accurate in identifying women with remaining cancer after chemo.

The chance that the test result came back clean, when cancer was actually present, happened about 12% of the time, but accuracy improved when additional techniques were used to narrow down the lymph nodes that should be removed.
