What is a cancer antigen level?
Cancer antigen 125 (CA-125) is a protein that may be found at higher levels in people with certain types of cancer and other health conditions. The CA-125 test checks the levels of this protein in the blood. The CA-125 test is a type of tumor marker test.
What is the normal range of cancer antigen?
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 cancer antigen marker?
What are tumor markers? Tumor markers are substances found in higher-than-normal levels in the blood, urine, or tissues of some people with cancer. These substances, which are also called biomarkers, can be made by the tumor. They can also be made by healthy cells in response to the tumor.
What is a bad CA 125 level?
In the patient who is being evaluated for a pelvic mass, a CA 125 level greater than 65 is associated with malignancy in approximately 90% of cases. However, without an obvious pelvic mass, this association is much weaker.
Does high CA 125 always mean cancer?
Does a high CA-125 always mean cancer? No, a high CA-125 does not always mean cancer is present. Generally speaking, the normal range of CA-125 is considered to be 0-35 units/mL, while a level above 35 units/mL is considered to be a high CA-125 level.
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.
Can you be fully cured of ovarian cancer?
Around two in ten women with advanced-stage ovarian cancer are effectively cured and survive at least 12 years after the treatment as per the research. Your response to cancer therapy and chances for a cure depend on the type and the staging of ovarian cancer at the time of diagnosis.
Would my WBC be high if I had cancer?
Does cancer cause elevated white blood cell count? Lung cancer can cause a high WBC count because of infections like bronchitis or pneumonia that can happen along with cancer. WBC counts increase when the immune system fights these infections.
How reliable are tumor markers?
There has been no evidence to prove that tumor markers are 100 percent reliable for determining the presence or absence of cancer. Many circumstances, such as other health issues or disease, can contribute to raised tumor marker levels.
What do tumor markers show?
A tumor marker is anything present in or produced by cancer cells or other cells of the body in response to cancer or certain benign (noncancerous) conditions that provides information about a cancer, such as how aggressive it is, what kind of treatment it may respond to, or whether it is responding to treatment.
