Sorry, it's took me so long to answer. It's not me, it's my dad. His cea was 47 in Feb. 2006 before surgery. After surgery it went down to 4.7 and back up to 7 and then 10, then they did a pet scan before starting treatments and it was clear. He has finished chemo and radiation in Dec. 2006. In April cea was 2.8 and July 9th it was 4.4.
