HI, I AM A 60 YEAR old female who was diagnosed with stage 4 colorectal cancer at the age of 54. I went through 11 Chemo treatments. My counts were good and everything was going well until recently, My CEA has consistently gone up for my last 6 checkups. Within the last 3 months, my counts have gone from 5.5, to 6.6 in two months, and now in the last month it went from 6.6 to 7.2. What do you feel this means? I have had a colon resection, and I do smoke about a pack a day, but I always have and after my treatments my CEA was normal.
