Warning Over Link Between

Deodorants & Breast Cancer

A controversial study which suggests a potential link between a common

chemical found in cosmetics and deodorants and breast cancer is published

this week.

 

Researchers looked at 20 human breast tumours and found synthetic chemicals

known as parabens in 18 of them, with high concentrations in four of the

malignancies.

 

It is the first time parabens have been detected within tumours, suggesting

that the man-made chemicals have accumulated in the breast tissue after

being absorbed through the skin.

 

But the study raises more questions than it answers, and cancer charities

last night urged caution over the results, stressing that they did not prove

a link between the cosmetics, deodorants or antiperspirants and the

development of cancer.

 

The study, published in the Journal of Applied Toxicology , did not show if

the chemicals are also found in healthy women's breasts, or what role they

might play, if any, in the growth of tumours.

 

Parabens are synthetic chemicals used to preserve goods from cosmetics such

as face cream, foundation and face masks through to the methyl and propyl

forms of the chemical as food preservatives. They are also used industrially

in oils, fats, shoe polish and glues.

 

Dr Philippa Darbre, cancer researcher at the University of Reading, who

carried out the study said: 'Finding these chemicals in human breast tumours

does matter, because we know from other work that they can mimic the way

oestrogen works to drive the growth of cancer.

 

'This is the first step; we need to see whether the chemicals are present in

the healthy tissue and, if so, what the concentration levels are. But we

have detected these intact molecules and I don't think it can be ignored.

 

'For years people have said there is no way they could enter the body

because of our physiology, but I think it is to do with a physical overload

of chemicals and that some are being absorbed by the skin. Women managed for

centuries without these materials and it has to be asked if we really need

them now.'

 

However, some of her previous research has been dismissed by scientists who

believe there is no clear evidence that the chemicals are linked to breast

cancer.

 

Instead, they blame an increase in obesity and women having children later

in life as the main reasons for the rise in breast cancer cases, from 20,000

cases in the late 1970s to almost 40,000 cases a year now.

 

Darbre has carried out other studies which she says show a link between

deodorants and cancer. Previously she looked at aluminium and zirconium

contained in the materials, which she suggested would have an effect on the

DNA controlling cancer growth.

 

For years, there have been concerns over whether deodorants or

antiperspirants could cause the cancer, although often the rumours seemed to

be more urban myth than reality.

 

Scientists have explained that physiologically it would be very hard for the

chemicals to penetrate to the breast, as the lymph glands would usually

clear away any toxins.

 

Dr Philip Harvey, European Editor of the Journal of Applied Toxicology, said

the results should be interpreted with caution. He added that the finding

was important because it showed that 'these oestrogenic chemicals can be

detected in the breast and are therefore absorbed'.

 

Karol Sikora, professor of oncology at Imperial College London, said: 'We

are all exposed to all kinds of chemicals, but it doesn't mean they all

cause cancer. The question is whether the chemicals would have an impact on

the hormones, and also what level you would see in a healthy breast tissue.'

 

Dr Richard Sullivan, Head of Clinical Programmes at Cancer Research UK,

agreed: 'It should be noted that the sample size is very small. No causal

relationship has ever been found between underarm cosmetics containing

parabens and breast cancer.'
