High calcium may be a marker for ovarian cancer

A small study, the first to demonstrate the potential of calcium as a biomarker for early detection, was based on data from 11 women who died from ovarian cancer during nearly 96,000 person-years of follow-up in two US population-based groups.

The risk for fatal ovarian cancer was found to be 52% higher for each 0.1mmol/L increase in total serum calcium and 144% higher for each 0.1mmol/L increase in ionised serum calcium.

The study was prompted by research from the same Wake Forest Baptist Medical Centre group which showed that men whose calcium levels were higher than normal had an increased risk
