Question 1

can you give me normal values for a ca 27.29 test?

Accepted Answer

Ca 27.29: Cancer antigen test for breast cancer is considered normal if the level is under 40 units per ml.  This test is however non-specific for breast cancer.

Question 2

what is a  ca 27.29 test result?

Accepted Answer

Depends on value: Ca27-29 is a marker used to follow the course of treatment in patients with advanced breast cancer. However, cancers of the colon, stomach, kidney, lung, ovary, pancreas, uterus, and liver may also raise ca 27-29 levels. Other conditions, including pregnancy, endometriosis, ovarian cysts, benign breast disease, kidney disease, and liver disease can also give elevations.

Question 3

can you give me info about a ca 27.29 test result?

Accepted Answer

Depends on value: Ca27-29 is a marker used to follow the course of treatment in patients with advanced breast cancer. However, cancers of the colon, stomach, kidney, lung, ovary, pancreas, uterus, and liver may also raise ca 27-29 levels. Other conditions, including pregnancy, endometriosis, ovarian cysts, benign breast disease, kidney disease, and liver disease can also give elevations.

Question 4

last blood work showed tumor marker ca 27.29 with # 46.3. it was #28.9 in oct , 22.6 in aug.surgery in dec. dr doing recheck in 2 wks. should i worry?

Accepted Answer

Possibly: Ca 27.29 increasing could signify a slight growth in your cancer ( i'm assuming that you have had an ovarian cancer resected )  however, the increase is not great and worth a repeat testing.  If is is slowly increasing then it might well represent tumor growth.

Question 5

last year my ca.27.29 level were 22 but now 38 via quest lab, they stated 38 or more is an issue. is my breast cancer reoccurring?  it has to be something bad if its 38 right?

Accepted Answer

: It is not necessarily the absolute value, but rather the pattern, in your case it sounds it has almost doubled, that would be of concern for the tumor marker. Your oncologist remains your best reference to clarify it in clinical context.

Question 6

my ca 27-29 has been slowly going up. i have metastatic breast cancer. my dr told me not to put so much emphasis on the numbers. i know it can be from inflammation. my gastritis and gerd has been severe. could it be that? worried?

Accepted Answer

: High CA 27-29 is not associated with severe gastritis or GERD.

Question 7

i have metastatic breast cancer. my ca 27-29 has been 45-60 (normal 40) i just tested and it was 138. i also just had a hysterectomy 5 weeks ago and they found ovarian cysts and endometriosis. could this be the reason it's higher?

Accepted Answer

: Endometriosis can cause elevations and recent surgery can cause elevations but I would strongly suggest seeing gyn onc and Breast cancer doctor immediately

Question 8

if tumor markers are consistently rising does it mean tamoxifen isn't working?  my ca27-29 went from the 20's to 48 to 52 and now 66 since october.

Accepted Answer

Setting?: Are you taking it after curative surgery (adjuvant) or to control metastatic disease?  Markers can be confusing. I have to say the progressive elevation of your 27.29 is suspicious but i'm taking it out of the context of your clinical situation. I'm sure your oncologist will gladly sit down with you and explain its meaning and what he/she has in mind for next.

Question 9

i have metastatic breast c. my ca27-29 went from 138 to 165 (normal 35) is this something to be worried about? i feel good. all lab work is normal?

Accepted Answer

: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, if the tests were done in the same lab indicate a slight increase that may or may not be meaningful.   
 Wish you good health!

Question 10

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?

Accepted Answer

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...
