What is the earliest identified tumor marker?
The history of currently used tumor markers began in the 1940s, the first discovered being alpha-fetoprotein in 1956, followed by that of carcinoembryonic antigen in 1965.
What are the different types of tumor markers?
There are many different types of tumour markers, including:
- alpha-fetoprotein (AFP)
- cancer antigen 125 (CA125)
- cancer antigen 15-3 (CA15-3)
- carbohydrate antigen 19-9 (CA19-9)
- carcinoembryonic antigen (CEA)
- human chorionic gonadotropin (hCG or beta-hCG)
- prostate-specific antigen (PSA)
What is meant by Tumour markers?
Listen to pronunciation. (TOO-mer MAR-ker) A substance found in tissue, blood, bone marrow, or other body fluids that may be a sign of cancer or certain benign (noncancer) conditions.
What does it mean when tumor markers go up?
Tumor markers are most often used to track how a patient’s cancer responds to treatment. If the level is going down, the treatment is working. If it goes up, the cancer may be growing.
What are the salient features of tumor markers?
The three most important characteristics of an ideal tumor marker are (a) it should be highly specific to a given tumor type, (b) it should provide a lead-time over clinical diagnosis and (c) it should be highly sensitive to avoid false positive results.
What blood test shows tumor markers?
A CA-125 test measures the amount of the cancer antigen 125 (CA-125) in a person’s blood. CA-125 is a protein that is a biomarker or tumor marker. The protein is found in higher concentration in cancer cells, particularly ovarian cancer cells.

What is tumor marker test?
A test that measures the amount of substances called tumor markers in tissue, blood, urine, or other body fluids. Most tumor markers are made by both normal cells and cancer cells, but they are made in higher amounts by cancer cells.
