In a new study scientists have found obesity also increases the risk of ovarian cancer. For years the link had mixed results among researchers. Today, American Institute for Cancer Research and World Cancer Research Fund released a report confirming it.
This is the first time any such reliable report confirms excess body fat may be probable cause for ovarian cancer.
Scientists say the increase is modest. Only risk of 6 percent is related to a 5-point increase in body-mass index or BMI in a woman.
According to National Institutes of Health, the BMI is a ratio of height and weight and above 25-point it is considered as overweight and more than 30-point is obese.
The new report has not seen any evidence that breastfeeding may reduce the ovarian cancer risk as several other report suggests. However, it calls the evidence to be limited ans only suggestive and not definitive.
The report also writes they have found evidence that taking oral contraceptives reduces the risk of ovarian cancer as it helps in reducing the number of times a woman ovulates.
In earlier several studies obesity has also been linked to variety of tumors such as thyroid, pancreas, kidney, uterus, colon, esophagus and also postmenopausal breast cancer.
American Institute For Cancer Research writes a healthy weight can prevent some of the cancers.
Every year more than 22,000 women in America are diagnosed with ovarian cancer and more than 14,000 are killed due to it, reveals data of American Cancer Society.
