How do lymph nodes aid in a cancer diagnosis?
What will be an ideal response?
ANSWER: The lymphatic system filters extracellular fluids. Therefore, if cancerous cells have
metastasized (spread from the initial location), it is likely that some cancerous cells may be
located in the lymph nodes. The examination of numerous lymph nodes surrounding the
primary site of the cancer may enable the physician to determine if localized treatment will
be effective or if a broader spectrum approach is necessary.
