Sentinel lymph node biopsy detects MCC spread in one third of patients whose tumors would have otherwise been clinically and radiologically understaged and who may not have received treatment to the involved node bed.
Sentinel lymph node biopsy followed by surgery
Sentinel lymph node biopsy is the removal of the sentinel lymph node during surgery. The sentinel lymph node is the first lymph node to receive lymphatic drainage from a tumor.
Sentinel lymph node biopsy is a procedure in which the surgeon finds and removes the sentinel (first) lymph node (generally one to three nodes) that receives drainage from the breast. The pathologist then examines it for cancer cells.
Sentinel lymph node biopsy - The sentinel lymph node is believed to be the first lymph node to which breast cancer is likely to spread from the primary tumor.
Definition A lymph node biopsy is a procedure in which all or part of a lymph node is removed and examined to determine if there is cancer within the node. Purpose The lymph system is the body's primary defense against infection.
During a sentinel lymph node biopsy, a radioactive tracer and a dye are injected into the site of the primary melanoma. These agents are then traced to the “draining' lymph node basin.

Since the appearance of a lymph node is important in categorizing the type of lymphoma that may be present, surgical removal of an entire, enlarged lymph node or nodes is sometimes preferable (lymph node biopsy).
Lymph nodes or abnormal tissue may be collected for examination. If necessary, a lymph node biopsy can be examined while the patient is still under anesthesia. If the lymph nodes show cancer, surgery may be done immediately (1).
In addition to a complete medical history and physical examination, diagnostic procedures for lymphadenopathy may include a lymph node biopsy in which a sample of tissue is removed from the lymph node and examined under a microscope.
