Breast Cancer & Antiperspirants: Is there A link?

One of the key reasons we started Indeora was to offer people a healthy and effective alternative to using anti-perspirants and the chemicals associated with them, in particular, aluminium.

There has been a lot of conflicting debate over the years on this topic but recent scientific studies by Professor Philippa Darbre do help to confirm some coincidental statistics that are really hard to ignore.


  • Antiperspirants applied to the underarm are generally left on the skin throughout the day, allowing for continuous exposure to the aluminium salts. This is the region of the breast where the majority of breast cancers start.
  • In the UK, research has shown over 50% of breast cancers start in the upper outer quadrant of the breast near the underarm.
  • Lifetime exposure to oestrogen is a risk factor for breast cancer.
  • Aluminium chloride and a chlorohydrate have been shown to act as metalloestrogens, capable of interfering with oestrogen action and under certain conditions stimulating responses associated with natural oestrogen. So using anti-perspirants is not good for reducing potential oestrogen exposure, especially as we get older.
  • Aluminium has been shown to be absorbed through intact skin from application of antiperspirant under the arm. When skin is damaged, e.g. when you shave, up to six times more aluminium can be absorbed.

Although it isn’t massively discussed yet in Ireland, countries like Switzerland are currently considering a ban or mandatory labelling on aluminum anti-perspirants as a result of recent medical research.

As consumers give more thought to the body products they are using, we have no doubt more and more people will make to the switch to healthier alternatives.

It’s getting harder to ignore the research and statistics so we hope you will make the switch to Indeora healthy magnesium deodorant and enjoy an aluminum and propellant free life for your underarms!!
