What Are Cancer Biomarkers?
Cancer biomarkers are genetic or biological markers on cells which may indicate cancer. These can be antigens produced by organs and bodily systems, or unique markers present in one’s DNA which may indicate an increased risk due to inherited defects. Their use and effectiveness at predicting cancer risk is still under investigation, although some studies have shown them to be accurate indicators for detecting cancer and sometimes other ailments.

Their use and effectiveness at predicting cancer risk is still under investigation, although some studies have shown them to be accurate indicators for detecting cancer and sometimes other ailments. Antigens can be cancer biomarkers which are produced by organs and other tissues. They secrete certain serums or fluids into the bloodstream, which then attach to cells. These cells can be tested for a particular antigen. Sometimes high levels of these markers can indicate that a tumor is present or that conditions may be right for the formation of a tumor. The location of cancer is determined by matching each serum with the organ or system which normally secretes it.
