My tumor was 2.7 cm on one ct scan and 3.4 on a later one. My concern was that I had two lymph nodes that lit up in the center of my chest. I had chemo and radiation before surgery. 20 nodes were removed during surgery. I was just trying to figure out if the nodes were cancerous and the chemo and radiation cleaned them up or if they were never cancerous to begin with. I did not have them checked until I was on the table for surgery, by then they were clean or they may have been clean all of the time. I was told it does not matter because all turned out well, but I just cannot help but to be curious.
