Lymphoseek® Lymphatic Mapping

Breast cancer can metastasize, or spread, to the first regional lymph nodes. Sentinel lymph node biopsy is performed to identify key lymph nodes draining from a primary tumor that may harbor cancerous cells. Often, there is more than one lymph node that is draining from a primary tumor that must be detected for accurate staging.

Lymphoseek uses nuclear medicine mapping to identify lymph nodes that have the highest probability of harboring cancer and is detectable within 10 minutes and up to 30 hours after injection. Lymphoseek transmits through the lymphatic vessels and begins to accumulate and bind in key lymph nodes draining from a primary tumor within minutes. This allows surgeons to better map the location of the primary tumor for removal. Lymphoseek is the newest tool in Mercy's arsenal of breast cancer surgery technology.
