HKBU research reveals that bisphenol S exposure may promote breast tumour progression and increase cancer risk
The research team carried out several experiments to explore how BPS exposure at environmentally relevant levels affects the development of breast tumours, including the tumour’s morphological characteristics as well as lipid and protein distribution, with the aid of mass spectrometry imaging technology.
The research team found that a low dosage of BPS induces faster tumour growth, and a high dosage of BPS may ultimately lead to deterioration of the tumour. Through comparing the distribution of lipids and proteins in the BPS-exposed mice groups with those observed in human breast cancer tissue samples, the team deduced that exposure to BPS will increase the risk of breast cancer in humans.
