Cleaning products may increase a woman's risk of getting breast cancer, according to a study published in Environmental Health.

The researchers found that more cases of breast cancer were reported for those who said they had been exposed to air fresheners and mold control products.

The results were derived from a questionnaire that asked women who had been diagnosed with breast cancer which cleaning supplies they used.

However, the American Cleaning Institute says that the study is full of errors.

"Simply put, this research is rife with innuendo and speculation about the safety of cleaning products and their ingredients," says ACI senior vice president of technical and international affairs Richard Sedlak.

The study's authors admit that the results have to be taken with a grain of salt. It's possible that those who believe chemicals in cleaning products cause breast cancer may have been more likely to report using them, they said.

The Breast Cancer Organization says that there are some risk factors that can and can't be controlled. People who want to decrease their risk of breast cancer should get exercise, eat a healthy diet and avoid smoking and excessive alcohol consumption.
