Cancer or tumour markers are chemicals produced by tumour cells, which can be detected in your blood stream. An elevated cancer marker reading can be an indicator of a particular form of the disease. While a positive cancer marker result is an indicator of a potential issue, it is not a guarantee, as there may be other reasons for elevated biomarker measurements in the blood. In the case of a positive marker reading, further detailed testing is advised.ULL
EBV is a cancer marker blood test related to nasopharyngeal cancer. Nasopharyngeal carcinoma is a cancer that starts in the upper section of the throat. While it is rare outside of Asia, in the south China region men have a one in 60 chance of contracting it in their lifetimes. This cancer appears to be linked to eating salted fish, as well as to a genetic susceptibility among Chinese to infection by the Epstein-Barr virus, the virus that causes mononucleosis. According to the Hong Kong Cancer Registry of the Hong Kong Hospital Authority, nasopharyngeal cancer is the 6th most prevalent form of cancer in Hong Kong among males.
