Researchers from Edinburgh University have revealed that drug letrozole, which is used to treat breast cancer, can increase the life span of people suffering from Ovarian cancer by three years.
The researcher used the drug to stop oestrogen from stimulating tumour growth.
Though the discovery may not benefit all because not all cases of ovarian cancer, which is also called a 'silent killer' are triggered by oestrogen, it still offers hope to thousands, reports Daily Mail.
The study that involved 44 women found that the drug stopped oestrogen supply to tumours for almost half a year, in 25pct of the women.
In one-third of the women, whose tumours were largely dependent on oestrogen, the drug deferred chemotherapy.
The researchers expect the drug to increase life expectancy from sa number of months to almost three years.
