Chinese researchers at the Department of Oncology at the First Affiliated Hospital of China Medical University who conducted a case-control study examining reproductive factors associated with breast cancer found a statistically significant 17% increased breast cancer risk among Chinese women who had induced abortions.
Peng Xing and his colleagues also found that, although breastfeeding protected women from any subtype of breast cancer, an increase in risk of breast cancer was associated with having more children among women who delayed their first full term pregnancy (FFTP) until after age 25 and never breastfed.
The researchers studied 1,417 women diagnosed with breast cancer between 2001 and 2009, and matched them with 1,587 controls without a prior breast cancer history.
The report was e-published by the National Center for Biotechnology Information of the U.S. National Library of Medicine.
This number is actually quite low compared to the 66% increase documented in the previous study from Turkish scientists, but the LifeSiteNews article explains why the 17% number is so low.
