London: It's a woman's weight which actually determines whether she has a risk of developing ovarian cancer -- taller women have a slightly higher chance of getting the disease, says a review of studies by Oxford University.
In its research, the British scientists analysed all worldwide data on the topic. It looked at 47 epidemiological studies in 14 countries, including 25,000 women with ovarian cancer and more than 80,000 women without ovarian cancer.
Lead researcher Prof Valerie Beral said, "By bringing together the worldwide evidence, it became clear that height is a risk factor. Ovarian cancer can be added to the list of cancers linked to obesity."
Sarah Williams, health information officer at Cancer Research UK, said the study produced a clearer picture of the factors that could affect a woman's risk of developing ovarian cancer, and found that body size was important.
"Women can reduce their risk of this and many other diseases by keeping to a healthy weight. For women trying to lose weight, the best method is to eat healthily, eat smaller amounts and be more physically active," she said.
The findings have been published in the 'PLoS Medicine' journal.
