How can you evaluate the tumor marker test?

How can you evaluate the tumor marker test?

They are not screening tests, they do not always go up if a cancer recurs, and they may go up for non malignant causes. They are a tool to be used as part of cancer management and are often misused, myself included. ...Read more

Not necessarily: Tumor makers are good for monitoring the response to treatment. Low or better yet, absent levels may mean that tumor is not there, however, more often it indicates a remission and levels increase if there is a recurrence. Therefore low levels of tumor markers do not always mean "no more cancer". ...Read more

If your tumor marker is greater than 0 but less than 40 (around 20-26) does it mean you still have cancer and chemo didn't get it all?

No..: It depends on what tumor marker you are referring to. In most cancers, tumor markers are never 0 even in healthy individuals that never had cancer. What is more important than the number is the trend in the values. So if within the last 6 months the number are 20, 60, 130, 220, then it is reason to be concerned. Otherwise, it should be followed serially. ...Read more

Can surgery cause a rise in a ca 27-29 tumor marker two months after reconstructive diep flap surgery?

No: This is a tumor marker...So like all tumor markers, its value is variable. So we use it, yet not rely on any single reading because the test results fluctuate. Because of this, many doctors do not use this test. Those who use it, are cautious not to take any one value on its face value and end up repeating it 2-3 different times. So I would ask your doctor to recheck it once or twice over 3-4 mos. ...Read more

Take 5000mcg biotin/day for hair & read it can falsely elevate AFP tumor marker results for HCC if u don’t stop for 72hrs before. Is this true?

Depends: 1. Taking biotin is not doing you or your hair any good.
2. Taking large amounts of biotin will interfere with some tests that use biotin as part of the reagents for the test.

Tumor marker ca27-29 went up again from 48 to 52 to 66 since oct. Two areas biopsied came back benign. Last CT last month. Could it still be cancer?

Tumor marker ca27-29 went up again from 48 to 52 to 66 since oct. Two areas biopsied came back benign. Last CT last month. Could it still be cancer?

I'm sorry, yes: When you were first diagnosed, if this tumor marker (ca27-29) was elevated, then it's rise likely means breast cancer somewhere. Other things can make it go up. But your doctor is probably checking to see if your cancer is back. Since your tumor is er positive, bone is a common place for it to come back without symptoms. Ask your doctor to explain what the rising ca27-29 means for you! Best... ...Read more

Can blood tests indicate the presence of cancer? I am quite worried that I have cancer, however I have had numerous blood tests (full cbc with diff, tumor marker, thyroid, etc) all coming back normal

Not really: Blood tests may be able to suggest or provide evidence against the presence of cancer, but generally cancers are found by pursuing testing or imaging based upon the history and physical exam. At your age the only screening tests for cancers you need should be breast, colon and if a long term smoker- lung CA. ...Read more
