Yes, My husband had several lymph nodes light up and were enlarged on the pet scan before surgery. They were nodes along the lilac chain. The surgeon was able to remove them along with his cecum and ascending colon. Pathology report came back with all those lymph nodes being cancer FREE!.. We were concerned that they missed something in the pathology, so we had everything sent to MDA, they did their own pathology on the nodes and tumor and surrounding tissue, and they confirmed that the nodes were free of cancer. Nodes can light up and become enlarged from infection, which they think was the case in my husbands situation. My husband , at diagnosis had an elevated WBC of 20,000.
I do hope that they are not cancerous.
