A surgical procedure: This is a surgical procedure to identify the first node that receives drainage from the site of the cancer, and is thus the node most likely to have cancer if cancer has spread. It is done routinely for breast cancer and melanoma. Thenode is removed and examined under the microscope for cancer. The results will help determine what additional treatments may be needed.
