A recent study in Mexico revealed that certain phthalates are associated with increased incidence of breast cancer. The study published in the Environmental Health Perspectives journal reviewed the phthalate urine concentrations of 454 Mexican women (223 with breast cancer and 221 as controls) and found a link between higher concentrations of phthalates and breast cancer incidence.
Phthalates are a group of compounds commonly found in artificial fragrances, deodorant, perfume, nail polish and certain plastic food packaging including articles such as baby bottles. Previous to this study, research indicated that this group of compounds has potential to affect the hormone system (endocrine disrupting effect). The exact link between this effect of phthalates and breast cancer has not yet been established however, the authors of the study suggest that it could be related to the DNA damaging effects of phthalates on breast cells.

Perfumes are a source of phthalates
Interestingly while some phthalate compounds (Monoethyl phthalate (MEP), which is a metabolite of diethyl phthalate (DEP)) were positively associated with higher breast cancer incidence, a number of other phthalate metabolites, including monobenzyl phthalate (MBzP) and mono(3-carboxypropyl) phthalate (MCPP), negatively correlate with breast cancer. The researchers suggest this is due to the ability of certain phthalate compounds to change gene expression without altering the genetic code of the cell.
As with all preliminary studies such as this one, it is important to note that while phthalates are associated with higher incidence of breast cancer, they aren’t necessarily responsible for the development of the cancer itself. Further studies in broader population groups will help establish a link, or not. Authors noted that additional research is need to identify the source of phthalate exposure, be it cosmetics, plastic packaging or a combination of many sources.

Editor’s comments: I am of the opinion that while there is no need to be alarmist about such studies, particularly as a direct link has not been established between phthalates and breast cancer. However, on the other hand I also think that where there is smoke there is fire. There is an easy solution – reduce your phthalate exposure. The easiest way to do this is to avoid the products in which they are commonly found eg. artificial fragrances in skin care, perfume, deodorant, baby bottles, plastic take away containers. Instead choose natural and organic skin care alternatives and use glass baby bottles and food storage containers. If you do get take away, just make sure you put it into ceramic or glass before heating in the microwave or take your own container to the restaurant!
