HCG is most often used to screen for cancer of the testis or ovary. Serial measurements monitor the progress and treatment of these cancers
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.
carcinoembryonic antigen, it is a tumor marker test.
It is a tumor marker for cancer of the colon and rectum
It is not advisable as there are no studies that say it is safe for a person who has had cancer previously. Cancerous tumors give off hcg as a means of protection from your own bodies antibodies. Should you have a precancerous or cancerous lesion or tumor in your body that has escaped detection, you could be inadvertently feeding those tumors the very protection they require to make inactive your own bodies fight against them. Hcg can help people but only if very very healthy, otherwise can also destroy if you have histories of serious illnesses. Please make sure you always check with your physician or oncologist, if you are thinking of using hcg.
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.
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)
Tumor markers are substances, usually proteins, that are produced by the body in response to cancer growth or by the cancer tissue itself.
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.
