Biomarkers that help researchers detect cancer (lat. Carcinoma) earlier was developed by scientists from Northwestern University. The main mission of the research is to identify biomarkers of the interplay of genes and environment in cancer. Precision medicine considers each individual’s genetic and environmental factors to determine treatment strategies. Also known as personalized medicine, this field rejects the idea that one drug or treatment works for all patients. Lifang Hou, a professor of preventive medicine and chief of cancer epidemiology and prevention at the Feinberg School of Medicine, focused on cancer biomarkers - biological indicators of the disease - in blood. Blood-based biomarkers, she says, will allow for simpler, lower-cost tests that can be deployed in physicians’ offices during routine check-ups. Equally important: These biomarkers are indisputable.
