Ovarian cancer has a high mortality rate because symptoms are often vague, allowing the disease to develop before it is properly diagnosed. This 2.4 minute clip from is from Sky News (though the same story was widely covered on other outlets on the same day). The piece reports findings from a new study in which a blood test looks for levels of a certain biomarker, a protein called CA125. The crucial thing in this study, which may pave the way for establishment of a screening programme, was the benefit of annual checks on the level of CA125 in a patient’s blood rather than a one-off check. It seems that absolute levels of the protein can be quite variable between different women, but a change in the level is a much more significant indicator of underlying developments. The approach of screening blood for cancer-related biomarkers is an emerging area in cancer treatment and might allow for screening for other variants too, such as prostate cancer.
