A lymph node dissection, also called a lymphadenectomy, removes lymph nodes. This surgical procedure is performed to remove cancerous lymph nodes or lymph nodes that have a high likelihood of developing cancer.
Why Are Lymph Nodes Removed?
Lymph node removal is primarily done for two main reasons:
- Cancer Treatment: If cancer is found within lymph nodes, they are surgically removed to prevent the spread of cancerous cells to other parts of the body.
- Preventative Measure: When there is a significant risk that cancer may spread to nearby lymph nodes, they are removed as a preventative measure to control the spread of disease.
What is a Lymph Node Dissection?
A lymph node dissection is a surgical procedure. It involves the careful removal of one or more lymph nodes from a specific area of the body. Lymph nodes are small, bean-shaped structures that are part of the lymphatic system.
How Is a Lymph Node Dissection Performed?
The procedure is performed by a surgeon. Here are the common steps involved:
- Anesthesia: The patient is given anesthesia so they don't feel pain during the procedure.
- Incision: The surgeon makes an incision in the skin, near the area with the affected lymph nodes.
- Removal: The surgeon carefully removes the affected lymph nodes.
- Closure: The incision is closed using sutures or staples.
