What are normal cancer marker levels?
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 does it mean when tumor marker is high?
A high level of a tumor marker may be a sign of cancer or certain benign (noncancerous) conditions. A tumor marker test is usually done with other tests, such as biopsies, to help diagnose some types of cancer.
What is considered a high level of CA-125?
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.

How accurate is a tumor marker blood test?
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 are the 3 markers for breast cancer?
In breast cancer care, three tumor markers — cancer antigen 15-3 (CA 15-3), cancer antigen 27.29 (CA 27.29), and carcinoembryonic antigen (CEA) — have been used to help monitor metastatic breast cancer (advanced disease), but they have not been found to be useful to find a breast cancer recurrence or lengthen lives …
What can cause CA 19-9 to Rise?
The reason for CA 19-9 elevation in benign disease can be explained by several mechanisms. First of all, inflammation and proliferation of non-tumorous tissue, such as in pancreatitis, cholangitis, bronchiectasis, idiopathic pulmonary fibrosis, ovarian cyst, and endometriosis, can elevate CA 19-9.
Can Tumour markers be wrong?
There’s a chance that a tumor marker test can give a “false positive.” That means the results suggest a person has cancer or that the cancer is growing, even when it’s not. A tumor marker can also give a “false negative,” which means the results suggest a person doesn’t have cancer when they actually do.
What is considered a high level for CA 15-3?
Cancer antigen 15-3 (CA 15-3) is used to monitor response to breast cancer treatment and disease recurrence. The reference range of serum CA 15-3 is less than 30 U/mL. The upper limit of the range varies depending on the laboratory and kit used for the test.
