I had my surgery a week ago wide excision and lymph nodes removed. They said I was an unusual case they do not normally remove all the nodes without proof but both the ct scan and pet scan showed enlarged nodes and they did try biopsy the nodes but this was negative but they said in there experience based on scans more likely to be positive so better to remove them so that is what happened. Still waiting for the results but when I saw the surgeon afterwards she said it was probably right to remove them.
