Potential link between aluminium salts in deodorants and breast cancer warrants further research

01.03.2006


Chemicals that mimic the body’s natural hormone oestrogen are known to affect a woman’s risk of breast cancer. Evidence is mounting that the aluminium-based compound, which often makes up quarter of the volume of some antiperspirant agents, can break through the skin and that once in the body it could mimic oestrogen. A review just published in the Journal of Applied Toxicology calls for further research to evaluate the potential that this could increase the risk of getting breast cancer.



Over recent years scientists have found that many compounds in the environment mimic or interfere with oestrogen. These compounds are normally complex molecules and are found in many plants, and used in materials like detergents, pesticides and plastics. Now scientists are realising that a variety of simple metal ions, including aluminium and cadmium can also bind to the body’s oestrogen-receptors and influence their action.

“Since oestrogen is known to be involved in the development and progression of human breast cancer, any components of the environment that have oestrogenic activity and which can enter the human breast could theoretically influence a woman’s risk of breast cancer,” says author of the review Dr Philippa Darbre, who works in the School of Biological Sciences, at the University of Reading, UK.


Aluminium salts in antiperspirants are a major source of exposure to aluminium in humans. It is often sprayed into armpits, inadvertently concentrating exposure near to the breast. In addition, it is often applied immediately after shaving, when the skin is likely to be damaged and less able to keep the aluminium out. “It is reasonable to question whether this aluminium could then influence breast cancer,” says Darbre.

Her concern is not confined to aluminium. Smoking tobacco introduces cadmium into the body, and research shows that it too can collect in breast tissue. There are indications that this accumulation of cadmium may also be linked to an increased risk of breast cancer, potentially showing one of the reasons why smoking could be linked to this disease.

“Each of these agents on their own may not have a powerful effect, but we need to see what happens when a number of them act together – it could be that this would have a significant effect on diseases like breast cancer,” says Darbre.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
