Tumor markers can be molecules that are produced in higher amounts by cancer cells than normal cells, but can also be produced by other cells from a reaction with the cancer. [ 2 ] The markers can't be used to give patients a diagnosis but can be compared with the result of other tests like biopsy or imaging.
Two areas in particular that are receiving attention as surrogate markers include circulating tumor cells (CTCs) [45] [46] and circulating miRNAs. [47] [48] Both these markers are associated with the number of tumor cells present in the blood, and as such, are hoped to provide a surrogate for tumor progression and metastasis. However ...
The CEA blood test is not reliable for diagnosing cancer or as a screening test for early detection of cancer. [8] Most types of cancer do not result in a high CEA level. [9] Serum from individuals with colorectal carcinoma often has higher levels of CEA than healthy individuals (above approximately 2.5ng/mL). [10]
Cancer biomarkers have an extremely high upside for therapeutic interventions in cancer patients. Most cancer biomarkers consist of proteins or altered segments of DNA, and are expressed in all cells, just at higher rates in cancer cells. There has not yet been one, universal tumor biomarker, but there is a biomarker for every type of cancer.

The major function of alkaline phosphatase is transporting chemicals across cell membranes. [1] Alkaline phosphatases are present in many human tissues, including bone, intestine, kidney, liver, placenta and white blood cells. [2] Damage to these tissues causes the release of ALP into the bloodstream.
Tumor antigen is an antigenic substance produced in tumor cells, i.e., it triggers an immune response in the host. Tumor antigens are useful tumor markers in identifying tumor cells with diagnostic tests and are potential candidates for use in cancer therapy. The field of cancer immunology studies such topics.
Tumor M2-PK is also useful to diagnose lung cancer and better than SCC and NSE tumor markers. [4] With renal cell carcinoma (RCC), the M2PK test has sensitivity of 66.7 percent for metastatic RCC and 27.5 percent for nonmetastatic RCC, but M2PK test cannot detect transitional cell carcinoma of the bladder, prostate cancer and benign prostatic ...
