Obesity a risk factor for ovarian cancer
Obesity is known to increase the risk for certain cancers, such as breast and bowel. Now, a study concludes that it may also raise the chances of developing ovarian cancer.
Researchers from the World Cancer Research Fund and the American Institute for Cancer Research reviewed 25 studies of four million women. Sixteen thousand had ovarian cancer. A correlation between obesity and ovarian cancer was noted when it became clear that for every five additional body index mass (BMI) units, the risk of ovarian cancer rose by 6 percent. Additionally, a non-linear analysis found that women with a BMI higher than 28.4 significantly increased their risk of ovarian cancer compared to women with a lower BMI.
This is considered a major finding to help in the fight to prevent ovarian cancer. As one researcher noted, only fixed risk factors such as age and family history were previously known, but now working to maintain a healthy weight may be a factor in preventing the development of ovarian cancer.
