Liver Cancer ranks third among the major causes of cancer-related deaths in Hong Kong.  It has been known for some time that liver cancer occurs far more frequently among men than women.  Scholars examined all relevant factors but no conclusive results were available until quite recently.  A research team at CUHK recently announces that the Cell-Cycle Related Kinase (CCRK), a gene significant in the process leading to abnormal liver cell growth and the formation of tumour, is directly controlled by the androgen, the male hormone.  There is proven link between the occurrence of liver cancer and a high level of CCRK.
