Chemicals widely used in sunscreen have been found in breast tissue \u2014 raising concerns about the potential health risk.<\/p>\n
The chemicals, used as filters to protect the skin from the sun\u2019s ultraviolet (UV) light, were found in 95 per cent of participants in a study undergoing mastectomies.<\/p>\n
The work was done by consultant breast surgeon Lester Barr, of the Prevent Breast Cancer<\/a> research unit in Manchester, and Philippa Darbre, a professor of oncology at the University of Reading.<\/p>\n

Findings: Chemicals widely used in sunscreen have been found in breast tissue \u2014 raising concerns about the potential health risk<\/p>\n
Breast tissue samples were taken from 40 breast cancer patients having treatment for the disease.<\/p>\n
The findings raise concerns about the cumulative effect of such products, say the researchers, because it suggests the chemicals do not stay on the skin, but seep into the body.<\/p>\n
\u2018We have no idea if the various chemicals we found in breast tissue are doing good, causing harm or just sitting there without doing anything,\u2019 says Mr Barr.<\/p>\n
\u2018The chemicals are not themselves known to be carcinogenic. However, in the lab, they do have the ability to mimic the hormone oestrogen. We need to know if they have any effect on breast tissue.\u2019<\/p>\n

The chemicals identified in the new study were benzophenone-3, octyl methoxycinnamate and 4-methylbenzylidene camphor<\/p>\n The three chemicals are found in many personal care products and are added to clothing marketed as UV-protective.<\/p>\n The research, co-funded by the charities Breast Cancer UK and Prevent Breast Cancer, published last month in the Journal of Applied Toxicology, found that in 95 per cent of women in the study, the UV chemicals were present in one or more regions of the breast.<\/p>\n The chemicals were found in healthy breast tissue that had been removed as part of the mastectomy procedure (researchers cannot use cancerous tissue, as it is needed for tests to determine treatment decisions).<\/p>\n The chemicals were present in minute quantities and, by themselves, say researchers, may not cause harm. Scientists now need to establish whether a particular combination of chemicals might work to have a cumulative harmful effect over a period of years.<\/p>\n The researchers stress that they are not suggesting people should stop using sunscreen, as it is vital to protect the skin from the sun\u2019s harmful rays and may help reduce the risk of skin cancer.<\/p>\n \u2018Many of these chemicals can be found in water, food and clothing, so avoiding one product is not going to eliminate the problem,\u2019 says Mr Barr. \u2018The issue is one of how society uses and disposes of plastics and chemicals.\u2019<\/p>\n Commenting on the study, Dr Christopher Flower, director-general of the Cosmetic Toiletry and Perfumery Association, says: \u2018All the UV filters reported in this paper have been assessed for safety . . . and are approved for use in sun protection products and are listed in the EU\u2019s Cosmetic Products Regulation.<\/p>\n \u2018Presence alone is no indication of toxic effect or potential for accumulation. Many substances are found in our bodies that are merely passing through and cause no harm while doing so.<\/p>\n \u2018The oestrogenic activity of these substances is far weaker than the synthetic oestrogens in the birth control pill, the use of which has been deemed safe for many decades.<\/p>\n \u2018There is a wealth of information that supports the safety of UV filters and nothing linking them to a decline in fertility or abnormal endocrine effects.\u2019<\/p>\n \u00a0<\/p>\n","protected":false},"excerpt":{"rendered":" Chemicals widely used in sunscreen have been found in breast tissue \u2014 raising concerns about the potential health risk.
