HMM: Scientists may have found early biomarker for ovarian cancer. “An antibody present in infertile women might also be an early biomarker for ovarian cancer, raising hopes that more lives can be saved with early detection of what is often called a ‘silent killer,’ since ovarian cancer is often not detected until late stages. Researchers at Rush University Medical Center in Chicago say that the marker could be an antibody that responds to the presence of mesothelin, which is found all over ovarian cancer cells, but in limited numbers on normal cells.”
