‘Symptom triggered’ testing can pick up early-stage aggressive ovarian cancer in 1 in 4 of those affected

Researchers found that symptom-triggered testing can pick up early-stage aggressive ovarian cancer in 1 in 4 of those affected. The UK's protocol for picking up early-stage disease is an effective way to diagnose even early-stage ovarian cancer, with complete surgical removal possible in more than three quarters of women.
