Mouthwash linked to cancer. Nejrozirenejsi klotadla mohou pusobit rakovinu ust. Meli by se stahnout z prodeje. Alkohol - etanol je na vine.

AUSTRALIA'S top-selling mouthwashes can cause oral cancer and should be pulled from supermarket shelves immediately.

Leading independent experts have issued this strong warning after investigating latest scientific evidence linking alcohol-containing mouthwashes to the deadly disease.

The ethanol in mouthwash is thought to allow cancer-causing substances to permeate the lining of the mouth more easily and cause harm.

Acetaldehyde, a toxic by-product of alcohol that may accumulate in the oral cavity when swished around the mouth, is also believed to be carcinogenic.

Smoking and alcohol consumption are well-established risk factors, but alcohol-containing mouthwash use is more controversial.

The review reported evidence from an international study of 3210 people which found daily mouthwash use was a "significant risk factor'' for head and neck cancer, irrespective of whether users also drank alcohol or smoked.

But the effects of mouthwash were worst in smokers, who had a 9-fold increased risk of cancers of the oral cavity, pharynx and larynx.

Those who also drank alcohol had more than five times the risk - and even those who neither drank nor smoked still ran a four- to five-fold risk of contracting cancer.

A Brazilian study has also found regular mouthwash use is associated with oral cancer regardless of alcohol or tobacco consumption.

Prof McCullough said the most popular mouthwashes contained higher concentrations of alcohol than drinks such as wine or beer.

"If you have a glass of wine, you tend to swallow it,'' he said.
"With mouthwash, you have a higher level of alcohol and spend longer swishing it around your mouth.

Eating while drinking increased salivation, which lowered the risks, he said.
