In a study published recently in the Journal of the National Cancer Institute, scientists pored over data of 1,636 women who have breast cancer by engaging a scientific analytical questionnaire with regards to breastfeeding.
In the recently concluded research involving women who have breast cancers, scientists are in agreement that breastfeeding moms have a distinct advantage over those who does not. Those mothers who practice breastfeeding are less likely to suffer cancer recurrence as compared to non-breast feeding mothers.
Breastfeeding has an excellent cancer retardation effect in certain types of tumors, which includes those hormone induced type. Cancer seems to have a lesser effect on women who engage in breastfeeding for more than 6 months.
Marilyn Kwan, lead team researcher, hails from the US and is a health care provider at Kaiser Permanente said, “This is the first study we are aware of that examined the role of breastfeeding history in cancer recurrence, and by tumor subtype. Women who breastfeed are more likely to get the Luminal A subtype of breast cancer, which is less aggressive, and breastfeeding may set up a molecular environment that makes the tumor more responsive to anti-estrogen therapy.”
While Co-author Bette Caan said, “Breastfeeding may increase the maturation of ductal cells in the breast, making them less susceptible to carcinogens or facilitate the excretion of carcinogens, and lead to slower growing tumors.”
The tumor seems to retard its spread to other body parts and can often be managed by drugs which includes aromatase and tamoxifen inhibitors.
Cancer relapse can not only be reduced by breastfeeding by about 30%, it also diminishes the risk of death by 28%. The longevity of breastfeeding activity is a protection against cancer.
Despite the fact that breastfeeding gives babies with adequate nutritional requirements they need for growth, it also provides natural antibodies for babies to help them overcome illnesses caused by viruses and bacteria. And now, the protective power of breastfeeding is an added incentive, against the effects of cancer on mothers.
