Ovarian cancer blood test can detect disease early, study suggests

Test that uses machine learning to find signs of the disease in blood could significantly improve patient outcomes

Scientists have developed a simple blood test to spot ovarian cancer early that could “significantly improve” outcomes for women with the disease.

More than 300,000 women, mostly over the age of 50, are diagnosed worldwide each year, according to the World Cancer Research Fund. Ovarian cancer is often diagnosed late, which makes treating the condition more difficult.
