Most women can report some benefits of breastfeeding such as colds and diseases? Yes, it a good way to connect with your baby as well.


But things get a little darker when it comes to one, a reason that can save lives for breastfeeding: a reduced risk of breast cancer. Although many studies have linked, it is surprisingly difficult to obtain direct answers. But several institutes have conducted studies regarding the same in an effort to define the connection between pregnancy, breastfeeding, and breast cancer.


You probably know that it can give your baby a good start. But that’s not the only health benefit. It can also reduce the risk of breast cancer.


A scientific study on breast cancer shows that there is strong evidence that it can reduce the risk for pre- and post-menopausal women.

Studies show that breastfeeding mothers reduce the risk of breast cancer before and after menopause. And breastfeeding longer than the recommended six months can provide additional protection.


Most women experience hormonal changes during breastfeeding that delay their menstrual period. This reduces a woman’s lifetime exposure to hormones such as estrogen that can promote the growth of breast cancer cells.


During pregnancy and breastfeeding, eliminate breast tissue. This detachment can help eliminate cells with possible damage to DNA, which reduces the likelihood of developing breast cancer.


It can also help reduce the risk of ovarian cancer by preventing ovulation. And the less you ovulate, the less estrogen and abnormal cells can become cancerous.



Does Breastfeeding Reduce the Risk of Breast Cancer?

Yes, it does, although the details are difficult to determine. There are four studies that are worth mentioning.


A large-scale analysis of approximately 150,000 women published in the periodical “The Lancet” in 2002 found that the risk of breast cancer for every 12 months of breastfeeding (i.e. with one or more children) was 4.3 percent compared to women who have not breastfeed.


A 2009 study published in the magazine “Archives of Internal Medicine” reveals that if a woman has a family history of breast cancer had reduced their risk of contracting menopause by approximately 60 percent when breastfeed.


A study published this year by the “Journal of the National Cancer Institute” found that women of African descent are particularly at risk of developing aggressive and intractable forms of breast cancer that are negative to estrogen receptors and triples being designated negative and the risk actually increases when a woman gives birth, but breastfeeding denies this risk.


Eventually, an international collaborative study on breast cancers, published in the periodical “Annals of Oncology,” revealed approx 20% reduction in the risk of breast cancer for hormone receptors negative in breastfeeding women. However, the researchers found that this subtype of difficult-to-treat breast cancer predominates, especially in women who have risk factors less likely to breastfeed, such as obesity, multiple or early pregnancies.





So, with all the above studies, it can be concluded that pregnancy and breastfeeding can help in reducing the risk of breast cancer.
