There are more than 20,000 new cases of ovarian cancer diagnosed in the united states each year.It remains one of the most difficult cancers to beat.

Now, new research in the journal Cancer suggests women might reduce their odds of ovarian cancer by maintaining a healthy weight.

Doctors followed more than 90,000 women for seven years.

They found obese women were nearly 80 percent more likely to develop ovarian cancer.

However the link only appeared in those who had *no* family history of the disease and who had not used hormone replacement therapy.

The theory is that the excess weight triggers more estrogen produce which in turn increases the odds for this cancer.
