Early pregnancy can reduce the risk of breast cancer
Research carried out by Fox Chase Cancer Centre in Philadelphia suggests that women who have children particularly early in life have a lower lifetime risk of breast cancerAbnormal, uncontrolled cell division resulting in a malignant tumour that may invade surrounding tissues or spread to distant parts of the body. when compared with women who do not.
The research identified a geneThe basic unit of genetic material carried on chromosomes. pattern found in breast tissueA group of cells with a similar structure and a specialised function. that differs between post-menopausalAfter the menopause - technically only once a woman has had no menstrual period for one year. women who had children, and post-menopausal women who did not. The results will help scientists to understand why pregnancythe period from conception to birth reduces breast cancer risk and may assist towards developing strategies that can provide similar protection for women who did not have children.
The study compared breast tissue from 44 post-menopausal women who had children, and 21 post-menopausal women who did not. Ricardo Lopez de Cicco, a Senior Research Associate at Fox Chase comments, "When a woman has multiple pregnancies beginning at a relatively young age, we see a protective effect against breast cancer. That is very important because it could begin to help us to understand why women who have children early benefit from a reduced risk of breast cancer throughout their lives."
