Better than the bottles. breastfeeding may protect the mother from breast cancer.
the longer a woman breastfeeds, the more protection it gains against breast cancer, say researchers who analyzed data of 147.275 women from 30 countries.
Breast cancer affects women of all walks of life, but the incidence is higher in developed countries, developed countries than poorer countries. One possible explanation for this phenomenon is that the term pregnancies and breastfeeding somehow protect women from developing breast cancer. Women in developed countries tend to have fewer children and breastfeed for a few months or not at all. But because women breastfeed after giving birth, researchers have struggled to separate the effects of breastfeeding from those of childbirth.
hope that many would overcome this obstacle, cancer researcher Valerie Beral and colleagues at Cancer Research UK in Oxford collected epidemiological patient raw data from 47 studies in 30 country. They analyzed data on 50.302 women with breast cancer and 96.973 women without the disease, control of several cancer risk factors for breast known as age at first pregnancy, menopausal status, and age at the time of the original study. The team reports in the July 20 edition of The Lancet that the risk of developing breast cancer decreased by 7.0% for each birth and decreased by an additional $ 4 3% for all 12 months in a woman breastfeeding. The tendency was for women of all ages in the developed and underdeveloped, and the authors say it helps explain why breast cancer is more common in Western countries.
The study is a "significant contribution" in the field of research on breast cancer, said epidemiologist John Baron of Dartmouth Medical School in Lebanon, New Hampshire. "We can finally very cleanly separate the beneficial effects of pregnancy effects of breastfeeding and quantify this protective benefit." It is "simply incredible" to see so clearly that what a woman in her reproductive years affects their health over 40 years later, he said.
