Breast cancer risk can be lowered in African-American women by breastfeeding, new research suggests.
Research led by Julie R. Palmer, ScD, of Boston University, found that having multiple children raised the risk of a kind of aggressive breast cancer known as ER-negative, but that breastfeeding reduced it.
"Women with two or more kids had 1.5 times the risk of getting ER-negative breast cancer compared with women who had no kids," Palmer told WebMD. "We found that increased risk was really only there for women who had not breastfed."
ER-negative (estrogen receptor-negative) breast cancer is more rare and more difficult to treat than ER-positive (estrogen receptor-negative) varieties.
The study looked at 59,000 African-American women from 1995 until 2009.457 had ER-positive cancer and 318 had ER-negative cancer.
