What is CA 15-3 in blood test?

Cancer antigen 15-3 (CA 15-3) is a protein that is produced by normal breast cells. In many people with cancerous breast tumors, there is an increased production of CA 15-3 and the related cancer antigen 27.29. CA 15-3 does not cause cancer; rather, it is shed by the tumor cells and enters the blood.

What is a normal level of CA 15-3?

CA 15-3 is measured in units per milliliter (U/mL). A normal test should be less than or equal to 30 U/mL. It is important to know that having a positive CA 15-3 blood test does not mean you have breast cancer or that your breast cancer has come back. Other conditions can cause CA 15-3 to be in your blood.

How accurate are ca 15/3 tumors?

CA 15-3 in the diagnostic and follow up of patients with breast cancer has a sensitivity ranging from 75-76.9% and the specificity ranging from 85.5-93%.

What is normal range for breast cancer tumor markers?

Interpreting Results

Tumor Marker	Normal Range
CA 15-3	Less than 30 units/mL
CA 27.29	Less than 38 units/mL
CA-25	0 to 35 U/m
CEA	Less than 2.5 ng/mL (non-smokers), less than 5 ng/mL (smokers)

What does it mean if CA 15/3 is high?

In general, the higher the level of CA15-3 in the blood, the more cancer there is in the body. The levels are highest when breast cancer has spread to the bones, the liver or both. If the level of CA15-3 goes down or returns to normal, it may mean that treatment is working.

What is the normal range for tumor markers?

Normal range: < 2.5 ng/ml. Normal range may vary somewhat depending on the brand of assay used. Levels > 10 ng/ml suggest extensive disease and levels > 20 ng/ml suggest metastatic disease.

What happens if tumor markers are high?

High tumor marker levels can be a sign of cancer. Along with other tests, tumor marker tests can help doctors diagnose specific types of cancer and plan treatment. Tumor marker tests are most commonly used to do the following: Learn if a person has cancer.

What is a high tumor marker for breast cancer?

Carcinoembryonic antigen (CEA), which belongs to a family of related cell surface glycoproteins, is the most widely used tumor marker in the clinical practice. It is a tumor marker for colorectal, gastrointestinal, lung and breast cancer.

Can stress cause tumor markers to rise?

The study, which followed 96 patients with chronic lymphocytic leukemia (CLL), found that those who felt more stress and anxiety about about their condition also had a higher volume of cancer cells in their blood and higher blood levels of markers for advanced disease.

What is a normal tumor marker level?

Normal range: < 2.5 ng/ml. Normal range may vary somewhat depending on the brand of assay used. Levels > 10 ng/ml suggest extensive disease and levels > 20 ng/ml suggest metastatic disease.

What is a good CA 125 reading?

The normal value is less than 46 U/mL. If your CA 125 level is higher than normal, you may have a benign condition, or the test result could mean that you have ovarian, endometrial, peritoneal or fallopian tube cancer. Your doctor may recommend other tests and procedures to determine your diagnosis.

What is a good CA 125 level?

The normal value is less than 46 U/mL. If your CA 125 level is higher than normal, you may have a benign condition, or the test result could mean that you have ovarian, endometrial, peritoneal or fallopian tube cancer. Your doctor may recommend other tests and procedures to determine your diagnosis.

What kind of cancers can be detected by CA 125?

The CA-125 test is a type of tumor marker test. This test is used in the process of monitoring a patient's response to ovarian cancer treatment, and detecting recurrence of ovarian cancer after treatment.

What level of ca125 indicates cancer?

The normal range for CA 125 is 0 to 35 units/ml. While a CA 125 level over 35 may indicate cancer, it does not always mean the person has cancer....CA 125 Levels Chart.

CA 125 Levels (units/mL)	Potential Cancer
>35 (high)	Possible cancer. More tests will be needed for a diagnosis.

Can tumor markers go up and down?

Tumor markers can go up and down over time, making it hard to measure them consistently. The level of a tumor maker may not go up until after the cancer is advanced. Some cancers don't make tumor markers that can be found with current tests.

What is a good ca 125 score?

The normal value is less than 46 U/mL. If your CA 125 level is higher than normal, you may have a benign condition, or the test result could mean that you have ovarian, endometrial, peritoneal or fallopian tube cancer. Your doctor may recommend other tests and procedures to determine your diagnosis.

Can stress cause CA 125 to rise?

The most popular current theories suggest that CA 125 is synthesized by mesothelial cells in response to stress, which can be either mechanical stress caused by fluid overload, or inflammatory stress instigated by the release of mediators such as TNFα and interleukins [5,6].
