Lymph nodes are often present in the breast tissue.The normal function of a lymph node is to act as filters.The size of a lymph node ranges from a couple of millimeters to about a centimeter. When there is infection or inflammation somewhere in the body, a lymph node may enlarge.The purpose of watching an enlarged lymph node is to ensure that the lymph node is not continuing to grow.
An enlarged lymph node doesn't necessarily mean cancer...and a 6 months follow up is the usual recommendation.The lymph node detected on your mammogram does not have suspicious characteristics to warrant a biopsy at this time.
