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: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Im Focus: A space-time sensor for light-matter interactions

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.

The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
