A sentinel lymph node biopsy is a surgery that takes out lymph node tissue to look for infection or cancer. Test results from are usually available within a few days. The lymph node tissue is usually treated with special dyes (stains) that color the cells so problems can be clearly seen.
Why It Is Done. A sentinel lymph node biopsy is done to: 1  See if a known cancer, such as breast cancer or melanoma, has spread to the lymph nodes.  Remove a few lymph nodes instead of removing all the lymph nodes in an area. If the sentinel lymph node does not have cancer, this surgery takes less time, is simpler to do, and has a lower chance of long-term problems, such as ongoing swelling of an arm or leg (lymphedema).
