Ovarian Cancer starts growing years before it can be diagnosed, says a research.

Researchers have taken a step towards the detection of this deadly disease. 34 women having ovarian cancer were detected, and 70 women not having cancer were studied under this research. Thier blood samples were taken which evaluated six proteins identified as potential indicators of ovarian cancers.

And under this study, they found out that levels of three proteins began to increase slightly in ovarian cancer patients three years before diagnosis but did not reach a level that could be detected in a screening program.

Ovarian cancer is the worst cancer in women amongst all the cancers of reproductive system. Women who are diagnosed in the earlier stages have a five-year survival rate of nearly 93 percent, according to the American Cancer Society.

In US, more than $2.2 billion is spent every year for the treatment of ovarian cancer as estimated by the U. S. Centers for Disease Control and Prevention.
