Women who use household products may be increasing their chances of developing breast cancer.
This is according to a recent report published in the journal Environmental Health.
The research, which looked at 1,500 women, compared those who used a combination of cleaning products with those who never touched them.
Slow-release air fresheners and anti-mould products were found to have the biggest effect, with women using a combination of the solutions found to be up to 110 per cent more likely to develop breast cancer.
Elizabeth Salter Green, director of CHEM Trust, commented: "Cancer, birth defects, diabetes, heart disease, obesity, are all end points in which it is felt that these man made chemicals in consumer products have a role to play."
She suggested that ventilating the home could avoid the need to use chemicals in some cases.
Breast cancer is the most common cancer in the UK, with almost 45,700 women diagnosed with the disease in 2007.
