Iran Study: Abortion Boosts Breast Cancer Risk 193% Study Finds, Giving Birth Lowers Risk
Researchers in Iran have published the results of a new study showing women who have an abortion face a 193% increased risk of breast cancer. On the other hand, women who carry a pregnancy to term find a lowered breast cancer risk compared with women who have never been pregnant.
The study follows on the heels of new reports indicating Komen for the Cure gave $7.5 million to the Planned Parenthood abortion business in 2009. [see this article on this webpage]
The findings were reported in the April 3, 2010 issue of Medical Oncology but are coming to the public's attention only now.
Hajian-Tilaki K.O. and Kaveh-Ahangar T. from Babol University of Medical Sciences compared 100 cases of women who were newly diagnosed with breast cancer compared with 200 age-matched controls to review several reproductive factors.
The researchers discovered abortion significantly elevated breast cancer risks. Also, having a first pregnancy at an older age increases the breast cancer risk by 310 percent — which has implications for women who have relied on birth control and delayed a first pregnancy until later in life.
The Iranian scientists also confirmed what other studies have found, namely that increasing parity or the number of births reduces the breast cancer risk significantly.
Reporting on the study, the FoodConsumer web site indicated women with parity equal to or greater than 5 reduced their breast cancer risk by 91 percent compared with women who had never been pregnant and not given birth. Each additional birth also reduced the breast cancer risk by 50 percent.
The Iranian study came just before another research study conducted by scientists in Sri Lanka, which found women who had an abortion in the past were 242 percent more likely to contract breast cancer.
That study was published in the journal Cancer Epidemiology and found a 3.42 odds ratio against women having abortions compared with those who kept their baby.
Abortion was the most significant factor in the study on breast cancer risk and researchers found a significantly reduced risk associated with prolonged duration of breastfeeding a newborn.
Malintha De Silva and colleagues from the University of Colombo led the study.
Combined with the Iranian study and others from the U.S., China and Turkey, five studies in the last 18 months have shown abortion elevates breast cancer risk.
In the one from the United States, Louise Brinton, a NCI branch chief, served as co-author.
She and her colleagues admitted that "…induced abortion and oral contraceptive use were associated with increased risk of breast cancer." The authors cited a statistically significant 40% increased risk of breast cancer following an abortion.
"It's becoming increasingly difficult for the NCI to keep its fingers and toes in the dike," said Malec, "especially since many researchers in other parts of the world do not depend on the agency for grants."
