PSA is a protein produced by the prostate gland and can be overproduced in prostate cancer. It is perhaps the best tumor marker in use because of its tissue specificity, meaning that it is produced only by the prostate.
The Bence-Jones protein is secreted into the urine where it can be measured. It was the first tumor marker identified.
M2-PK is a new tumor marker for ovarian cancer with a sensitivity of approximately 70%
Tumor marker tests usually require 5-10 mL of blood.
PSA is a bit of a confusing marker, when trying to measure what its number means. A 3.4 marker level is a bit higher than what most physicians deem "normal". However, in order to determine whether your PSA is rising, which is the concerning factor, you need to first determine where it is rising from.
carcinoembryonic antigen, it is a tumor marker test.
It is a tumor marker for cancer of the colon and rectum
Human chorionic gonadotropin
Each tumor marker has a unique life span in the blood. To monitor a treatment's success, enough time must have passed for the initial marker to be cleared from the blood. Tests done too soon may be falsely elevated.
HCG is most often used to screen for cancer of the testis or ovary. Serial measurements monitor the progress and treatment of these cancers
Tumor markers are substances, usually proteins, that are produced by the body in response to cancer growth or by the cancer tissue itself.
AFP : alpha feto protein. This is the main tumour marker used in germ cell tumours, i.e. testicular, ovarian and teratoma. AFP also is the most specific and ideal tumor marker for primary carcinoma of liver (Hepatocellular Carcinoma)
There is a tumor marker for some cancers of the colon; it is known as carcinoembryonic antigen, or CEA. Unfortunately, this protein may be made by other adenocarcinomas as well, or it may not be produced by a particular colon cancer.
