The impact of parity and age of first full-term births on frequency of ER- BC

Dr Maja Van Goistenhoven, a gynaecologist in formation at the KULeuven, presented a poster on the association between reproductive factors such as parity and age at first full-term births and the frequency of estrogen receptor-negative breast cancer according to age at diagnosis. This was a large institutional study on all patients diagnosed and/or treated with early breast cancer in UZ Leuven between January 2000 and November 2020.
