Dear girls8: Lymph nodes are often present in the breast tissue. The normal function of a lymph node is to act as filters. The normal size of a lymph node ranges from a couple of millimeters to about a centimeter. When there is infection or inflammation, a lymph node may enlarge. The purpose of watching an enlarged lymph node in the setting of a negative mammogram is to ensure that the lymph node is not continuing to grow, which may be cause to investigate further.
