RESEARCHERS are looking for 500 women to take part in a study aiming to develop a screening programme for those most at risk from ovarian cancer.
Women with a family history of the disease face the greatest dangers of also developing it.
Researchers from University College London hope that studying women from these families will lead them to finding the best way of screening those most at risk.
Researcher Lindsay Fraser
said: "Taking part in the study involves blood tests three times a year and annual non-invasive scanning until 2011 and completing two follow-up health questionnaires."
The study has already recruited about 2,500 women across the UK, but another 500 are needed.
Dr Fraser added: "Women from high-risk families are asked to see their GP with details of their cancer history.
"Their GP may refer them to a specialist unit at a hospital, as appropriate."
Every year about 7,000 women in the UK are diagnosed with ovarian cancer, with more than 4,600 deaths.
The Cancer Research UK charity says most cases are diagnosed at a late stage, meaning that five-year survival rates remain low despite advances in treatment.
The research has been jointly funded by the charity, the National Cancer Institute in the US, the Government and The Eve Appeal.
