A small incision is made so that these nodes can be removed and sent to the pathology department for immediate frozen section biopsy to determine if any cancer cells are present. If no cancerous cells are found, it is a good indicator the cancer has not spread out of the breast. However, if cancer cells are found in a sentinel lymph node, the standard of care is for the surgeon to proceed with an axillary dissection surgical removal of additional lymph nodes in the armpit to make as certain as possible that all lymph nodes containing cancer have been eliminated.
Before the development of the sentinel lymph node mapping procedure, the only available method to check for presence of cancer in the lymph nodes was a more invasive axillary dissection. Unfortunately, axillary dissection includes a greater risk of side effects, including pain, nerve damage and chronic swelling of the arm.
Although sentinel lymph node biopsy does not completely eliminate the risk of these side effects, the likelihood of a persistent problem is greatly reduced. For a day or so after sentinel lymph node mapping, the body eliminates the blue dye through urination.
Although the urine typically appears blue to green, the dye is harmless to the kidneys and urinary system. Once they find the area where your sentinel node s are, they will make an incision surgical cut.
They will look for the blue sentinel node s and remove them. They will send the node s to the Pathology Department to see if they contain cancer cells. If the sentinel node s do contain cancer cells, you might need to have more lymph nodes removed. This is called an axillary lymph node dissection. Your surgeon will discuss this with you in more detail, if needed. You might go home the same day as your biopsy, or you may need to stay in the hospital.

The lymphatic system includes the spleen, thymus, lymph nodes and lymph channels, as well as the tonsils and adenoids.
Sentinel node biopsy is recommended for people with certain types of cancer to determine whether the cancer cells have spread into the lymphatic system.

Sentinel node biopsy is generally a safe procedure. But as with any surgery, it carries a risk of complications, including:. Although lymphedema is an unlikely complication of sentinel node biopsy, one of the main reasons sentinel node biopsy was developed was to decrease the chance of developing lymphedema, which is more likely to occur if many lymph nodes are removed from one area. Because only a few lymph nodes are removed, the risk of lymphedema after sentinel node biopsy is small. Dozens of other lymph nodes remain in the area of your body where the sentinel node biopsy is done.
In most cases, those remaining lymph nodes can effectively process the lymph fluid. Your doctor might ask you to avoid eating and drinking for a certain period of time before the procedure to avoid anesthesia complications. Ask your doctor about your situation.
Radioactive solution. In this option, a weak radioactive solution is injected near the tumor.
