Has anyone else heard this before? Are there any other things that can cause CEA levels to fluctuate similarly to how cigarette smoke does?
The other questions are: as a colon cancer
patient who completed chemotherapy about 3 years ago and is currently NED, does having gone through chemotherapy contribute to an acceleration of tooth decay and bone loss and bone decay in general across the body? A front tooth fell out about a year-and-a-half or about 2 years after 6 months of chemo was completed at the age of 67 and just a few days ago one of the wisdom teeth started to become loose at 69, making it hard to chew on that side of the mouth.
And is it possible that going to see the dentist and having a loose tooth extracted or other dental work done can impact one's CEA levels?
Thanks in advance for your feedback.

I had a reading of 4.4 and then my scan came back that I had walking pneumonia. It went down to normal after 2 weeks on antibiotics.
A benign cause is virtually never the cause of a CEA reading of 10 or higher. CEA can rise up to 8 months before a met is large enough to be seen on a CT /PET scan.
CEA's can jump all over the place. Make sure you're well hydrated before blood work. If you're sick, reschedule the blood work.
As an aside, as we age, our CEA will be slightly higher. In some countries, Roche Labs has changed the reading norms according to age. I wrote last year to ask when that will be noted in the U.S. and I got a long explanation blaming the FDA and AMA. An obese woman / man has a lower CEA than a slim/ normal sized person.
I've lost 3 molars to chemo and don't have the money to put in implants so .....

As you can see, it seemed pretty stable at 1.9 except for a dip down to 1.6 and 1.7 during the first 5 quarterly blood tests - nothing over 2.0. Then on the 6th quarterly blood test 2.1. The oncologist said that there's no need for alarm unless you reach 5.0 and that if it ever reached 10.0 an immediate CT scan would be ordered rather than waiting for what is now supposed to be an annual CT scan after 3 years of clear bi-annual scans.
Then on blood tests 7 and 8, it jumped to 3.0 and 3.1, respectively. It didn't seem to stick around in 2.x range at all and went straight to 3.x, which is causing some personal concern, even though it's still below 5.0. And the trend for the past 4 quarterly blood tests has been upward, with no dips that were seen previously in earlier history you see.
10/31/15 - 1.9
1/26/16 - 1.6
4/30/16 - 1.9
7/28/16 - 1.9
10/29/16 - 1.7
1/28/17 - 2.1
4/29/17 - 3.0
7/29/17 - 3.1
Aside from perhaps a lost tooth and some pain in a wisdom tooth, there were no infections or exposure to cigarette smoke right before the last two blood tests that can be recalled. Just trying to make sense of this and determine if there is justification for concern.
Next quarterly blood test is later this month of October, towards end of month.

Dentist says it is due to reduced salivation and wanted root canal. But Med oncologist has forbidden the same.
Thankful to have survived with a couple of lost teeth and occasional bone and muscle pain.
