Lactating Mothers have Better Chances of Avoiding Cancer Recurrence as long as they breastfeed their babies for at least 6 months


A research study was published in the Journal of the National Cancer Institute in which the scientists pondered over records of 1,636 women diagnosed with breast cancer through employing a scientific analytical questionnaire about breast feeding.

As a conclusion to the research which involved women with breast cancer, breastfeeding mothers have a distinctive gain over those who are not and that they also suffer less recurrence of breast cancer compared to the non-breastfeeding mothers.

According to the researchers, breastfeeding has an excellent cancer retardant effect particularly with certain types of tumors including those induced by hormones. The effects of cancer are greatly reduced in mothers who breastfeed for over 6 months.

Marilyn Kwan, lead team researcher and a health care provider in Kaiser Permanente who is hailed from the United States, verbalized “This is the first study we’re 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.”

“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,” as commented by Bette Caan, co-author.

The spreading of the tumor tends to stop to other parts of the body and is manageable with medications which include aromatase inhibitors and tamoxifen. Aside from reducing cancer recurrence for about 30%, the threat of death was also decreased by 28% with breastfeeding. It is believed that the protection against cancer is even better depending on the frequency and longevity of breastfeeding.

Breastfeeding gives the babies with necessary nutritional requirements and natural antibodies for them to overcome and be protected against diseases brought by either bacteria or viruses. Besides to its other benefits, breastfeeding has finally known now to protect the mothers from the possible effects cancer.
