Is there a causal relationship between the uptake of aluminium and the development of breast cancer?
Based on the current scientific status, the Federal Institute for Risk Assessment (BFR) sees no scientifically demonstrable causal connection between the development of breast cancer and the uptake of aluminium. Tumours in the breast are frequently located in the region of the armpit. This is why antiperspirants containing aluminium salts – in contrast to deodorants – are suspected as being factors capable of triggering breast cancer. But in this case too, based on the available scientific facts, the Federal Institute for Risk Assessment (BFR) sees no evidence of a causal connection – even when the cosmetic agents come directly into contact with the skin.
