Molecular signal in blood helps detect early risk for ovarian cancer, study finds

Researchers discover a potential diagnostic breakthrough for a disease often ⁠discovered after it has already spread

A molecular signal in the blood helps identify microscopic changes that precede development of ovarian cancer, researchers have found, ⁠a potential diagnostic breakthrough for a disease often ⁠discovered after it has already spread.

For decades, ​efforts to detect ovarian cancer earlier have focused on finding smaller tumors, the researchers noted in their report published on Tuesday in Nature Medicine.
