Dear Metjet, When your son goes to see the surgeon they will discuss doing a biopsy of the lymphnodes. A biopsy of the lymphnodes involves removing one of the enlarged lymphnodes or taking a needle biopsy of it. This is not an extensive procedure and different from the type of procedure done for breast cancer surgery. Lymph nodes can fluctuate in size, for instance, when the body is fighting infection they can become temporarily enlarged.
When you see the surgeon ask about what procedure they plan to do, what is involved in the care of the site if a biopsy is done, what may be complications you should watch for, and what to report. Ask when results of the biopsy will be available, when to expect a call, or will a follow up visit be scheduled.
