Lahore (Online): A chemical found in countless everyday products ranging from plastic food containers to banknotes and receipts may increase the risk of breast cancer according to an alarming study .

The hormone-disrupting chemical, known as Bisphenol S (BPS), has been found to alter a gene linked to the disease.

Researchers warned BPS mimics oestrogen and may have the same hormonal effects as the so-called gender-bending chemical Bisphenol A (BPA), which has previously been linked to breast growth in men.

As a new area of research, it's unclear how much BPS exposure is required to raise an individual's breast cancer risk. 

Yet, experts are now warning any plastic exposure may carry breast cancer concerns.

Study lead author Dr Sumi Dinda said: 'Despite hopes for a safer alternative to BPA, studies have shown BPS to exhibit similar estrogen-mimicking behavior.' 

According to the National Cancer Institute, 55 to 65 per cent of women who inherit a harmful mutation in the BRAC1 gene will develop breast cancer

The scientists, from Oakland University in Michigan, exposed breast cancer cells to varying BPS strengths or an inactive control.

The scientists found that BPS caused breast cancer cells to multiply. 

Compared with the control, BPS increased oestrogen receptor and BRCA1 gene activity after just 24 hours.

After six-days, the breast cancer cells exposed to the lowest BPS dose reportedly increased by 12 per cent, with an increase of 60 per cent at the highest dose. 

Dr Dinda stressed that further studies investigating BPS in breast cancer are required.

But, he added: 'If a woman has a mutated BRAC1 gene and uses products containing BPS, her risk for developing breast cancer may increase further.'

This comes after French scientists found that BPA exposure may prevent dental enamel development in children.
