Conservapedia's sub-article on Abortion and Breast Cancer claims that there is an undeniable link between breast cancer and abortions:
The vast majority of scientific studies have shown that abortion causes an increase in breast cancer, including 16 out of 17 statistically significant studies.
A new study coming from researchers in Sri Lanka finds women who had abortions ... [had a] 3.42 [increased risk] ... compared with those who kept their baby. ... The Sri Lankan study is the fourth epidemiological study in fourteen months to report an abortion-breast cancer link, including studies from the U.S., China and Turkey.
LifeNews also reported in 2010 that a National Cancer Institute researcher admitted there was a link between abortion and breast cancer. Studies showing that abortion increases breast cancer predate the political controversy. A study at the Fred Hutchinson Cancer Research Center published in 2009 confirmed a 40% increase in risk in breast cancer from abortion. Yet the abortion industry conceals this increased risk, just as the tobacco industry concealed its cancer risk for decades.
Yet the National Cancer Institute's article on Abortion, Miscarriage, and Breast Cancer Risk says the opposite:
They concluded that having an abortion or miscarriage does not increase a woman’s subsequent risk of developing breast cancer.
So which one is correct?
Does Abortion lead to an increased risk of Breast Cancer?
