[|Human|] All most a year ago I had an infection in my left foot, which was extremely swollen and extremly painful to walk. Later the bottom left leg (under the knee) also swelled up. No swelling above the knee. My Vascular Surgeon was watching it as they found an enlarged lymph node in left groin. After watching it for several months he decided to do surgery as it was increasing in size. I am to have the procedure at a Surgical Center tomorrow. Can you explain what can I expect if the biopsey is cancerous. Thank you for your time.
[|AI|]  Cancer in the lymph nodes does not arise per se and comes from a neighboring structure in this case your leg. So, if the lymph node shows presence of cancer, then it is likely that the leg also has cancer from where the cancer has spread to the nodes. In such a case, you would have to first rule out that the cancer has spread to other parts of the body. If not, then you will need to undergo surgery of the leg (to take out the entire tumor--may result in amputation) and surgery for removal of all nodes from the groin.
