Information stating that antiperspirants can cause cancer is flowing around the media for a couple or years. The first such claims revealed that the underarm area (in which antiperspirants are applied) it’s the same zone where the lymph nodes are presents and where cancer cells can appear, leading to breast tumors. Other concerns related to the antiperspirants causing cancer were the ingredients used in deodorants, such as aluminum and parabens, both being easily absorbed by the skin and constituting an important factor in the developing of breast tumors.
Doctors and scientists so far tried to explain that this may not be a cause and effect matter, and no conclusive proof was yet to be found that makes antiperspirants the cause of cancer. As most doctors stated, the presence of parabens in breast tumors does not mean that such a compound triggered the cancer.

Recently, researchers from the United Kingdom found evidence suggesting that paraben is present in all the tissue affected by cancer, even in tissue that was not exposed to any kind of antiperspirants. As far as UK researchers are concerned, antiperspirants do not cause cancer.
The studies that were conducted by the UK researchers state that 99% of the tissue samples had at least one paraben present, while 60% of the samples had no less than five distinctive parabens. The scientists were not surprised by those findings, given that parabens are used as a preservative for shampoos, moisturizers, make-up, pharmaceuticals and those parabens can even be found in food products.
Despite all the studies conducted so far, more and more people are having concerns about parabens causing cancer, especially the effects of antiperspirants, products that are used on a daily basis.
FDA (The United States Food and Drug Administration) stated that the risk of parabens causing cancer is quite low and the use of antiperspirants should not cause cancer.
