Thank you for posting the link above and also for summarizing the CEA situation in your previous posts.
I wish that that these types of summaries had been available 5 or 10 years ago. It would have helped clarify a few very important points and would have saved a lot of people a number of months of unnecessary anxiety.
The verywellhealth November 2019 article that you cited above contains a current and comprensive, readable overview of the subject and, in my opinion, should be required reading for all newly diagnosed CRC patients.
