An abortion can triple a woman’s risk of developing breast cancer in later life, researchers say.
A team of scientists made the claim while carrying out research into how breastfeeding can protect women from developing the killer disease.
While concluding that breastfeeding offered significant protection from cancer, they also noted that the highest reported risk factor in developing the disease was abortion.
Other factors included the onset of the menopause and smoking.
The findings, published in the journal Cancer Epidemiology, are the latest research to show a link between abortion and breast cancer.
The research was carried out by scientists at the University of Colombo in Sri Lanka.
It is the fourth epidemiological study to report such a link in the past 14 months, with research in China, Turkey and the U.S. showing similar conclusions.
