Can a surgeon tell if a lymph node is cancerous by looking at it?

Lymph nodes deep in the body cannot be felt or seen. So doctors may use scans or other imaging tests to look for enlarged nodes that are deep in the body. Often, enlarged lymph nodes near a cancer are assumed to contain cancer. The only way to know whether there is cancer in a lymph node is to do a biopsy.
