Over 1,500 women are diagnosed with ovarian cancer in Australia every year.
1000 of those women will die of the disease. That is one woman every eight hours.
Other than family history, researchers have struggled to identify any other potential risk factors. Until now.
This month, a study published in Epidemiology, linked regular douching to an increased risk of developing ovarian cancer.
Douching involves washing or cleaning out the vagina with water, vinegar, baking soda or iodine. Douching kits are sold in some shops, and include a nozzle which assists in inserting the mixture into the vagina.
Doctors and public health officials have been warning against the cleaning technique for decades, given that the practice can lead to a number of health problems, from recurring yeast infections, to pelvic inflammatory disease. Douching is widely understood to disrupt the healthy bacteria in the vagina.
According to a study out of the US found that 20 per cent of women continue to douche despite health warnings.
