i finished radiation and chemo eight weeks ago. On wednesday i went for a cat scan of the neck and a body scan. no changes where found on the scan, it showed the same suspicious thing as the scans prior to chemo and radiation treatment. the dr. believes that it is a false positive because it was done too soon and the tissue might still swollen from treatment. He recommends another scan in eight weeks. Has anyone heard of this? should i get a second opinion? i go to sloane kettering for salivary gland cancer treatment and they are world known but this is really bothering me. if it was too soon what they sent me to do it? i open for opinions.
