What is the lymph system?
- It is small tubes that are in your body tissues
- It contains infection-fighting white blood cells called lymphocytes
- Lymph nodes are small glands that help balance fluids and get rid of waste materials
- The lymph system also includes the spleen, thymus and bone marrow (Marion and Potts, Choices 2003, pp. 697, 196, 197, 422, 423)

Why do I need lymph nodes or the lymph system?
- To help prevent infections and injury
- To help fluids drain from your arms and legs

The lymph fluid:
- Is not able to drain from your arms
- May contain bacteria or wastes that stay in your arm(s) or leg(s) (soft tissues).
- When bacteria and wastes stay in your tissues (rather than draining away), they have time to grow and become infections.
- Causes pressure that may also cause pain
- The providers need look at your lymph nodes to see if they have any cancer cells in them
- If they see cancer cells in one or more lymph nodes:
- Then your cancer may have spread to other parts of your body
- The type of treatment you get will be different from someone else who does not have cancer cells in their lymph nodes
- The lymph nodes are very small and it is easy for the surgeon to accidentally cut a lymph node
- Radiation can also damage the lymph nodes
- Lymph nodes may be removed at the time of the first biopsy. Other times lymph nodes are looked at or removed after receiving the biopsy results.
- Sometimes things happen so fast you may not even realize what is happening.
