    I have heared roumors that parabens cause breast cancer. Is this true? I have also heard that the ink on till slips can cause cancer. Is this true?

    • Debbie @CANSA says:

      Dear Nicole

      Thank you for your query. It is not the ink on the till slips which is problematic, it is the Bisphenal A (BPA) in the paper of heat sensitive till slips that is the problem. This is being replaced by BPS. See more info on BPA here:

      Please see more information regarding PBS and till slips here in our Fact Sheet:

      If you have any further queries after reading this, please direct them to FOR ATT: Prof Michael Herbst & Dr Carl Albrecht.

      I have referred your query re parabens to our Research & Health Team for comment.

      Dear Nicole

      Please find a response to your query re parabens by CANSA’s Head of Health, Prof Michael Herbst, below:

      Parabens are a group of compounds widely used as antimicrobial preservatives in food, pharmaceutical and cosmetics products, including underarm deodorants. Parabens are absorbed through intact skin and from the gastrointestinal tract. Measurable concentrations of six different parabens have been identified and found in biopsy samples from breast tumours. The particular parabens were found in relative concentrations that closely parallel their use in the synthesis of cosmetic products.

      Should you have any further queries re this, please contact him via FOR ATT: Prof Michael Herbst
