Basque Research -- A team of researchers at CIC bioGUNE has revealed that oestrogen can reduce the risk of breast cancer. Their work shows that oestrogen is capable of reducing the number of breast cancer stem cells, which may explain the lower aggression of the tumour and, as a consequence, the possibility of a better prognosis. The project was published in Breast Cancer Research and Treatment and the team will present the results under the auspices of the International Conference on Breast Cancer to be held in Madrid. The research combined the use of human samples and laboratory cell lines.
