Faulty gene raises ovarian cancer risk
A single faulty gene has been found to raise the risk of ovarian cancer six-fold, giving a woman more than a one in 11 chance of developing the disease.
The discovery was hailed as a "landmark" by cancer research agencies.
It paves the way for an early diagnostic test which could be available within two to three years.
UK scientists also believe women with the mutation should respond to treatment with a new class of anti-cancer drug.
