My dad was diagnosed with stage IV colon cancer in May 2002. He had part of his colon removed and one spot removed from his liver. He began chemo in August 2002. He finished his treatment in September 2003. He has had clean pet and cat scans since his operation. Every month, his doctor monitors his CEA. In December 2003, his blood levels were perfect and he had a clean pet scan. In January, his CEA level was fine. All of a sudden, in February, his CEA level increased slightly according to his doctor. Now, his doctor wants the blood test every two weeks instead of once a month. My dad was scheduled for a cat scan before the increase in his CEA level. He had the cat scan on March 1 and will have his next blood test on March 5. We will get the results on March 12. I believe his CEA level is 4. I also believe that even before his first surgery (May 2002) his CEA was 3.? I do not know the numbers after that. Is this something I should worry about? Has this happened to anyone else??
