New research suggests that women who are obese may be more likely to need ovarian cancer treatment.
Obesity has previously been linked to a number of cancers, including bowel, womb, pancreatic and postmenopausal breast cancer.
Now, scientists at the US National Cancer Institute have found that, among women who have never used hormone replacement therapy (HRT), obesity is associated with an almost 80 per cent higher risk of ovarian cancer.
However, the link does not appear to hold true for women who have ever used HRT.
The findings are published in Cancer journal and the researchers concluded that the observed link between obesity and ovarian cancer risk has "relevance for public health programmes aimed at reducing obesity in the population".
Around 6,800 women are diagnosed with ovarian cancer in the UK each year and the nation has one of the highest rates of ovarian cancer in Europe, according to Cancer Research UK.
